  • BASF Launches Operation Weed Eradication to Help Growers Eradicate Weeds

    BASF launched a new industry-wide initiative to eliminate on-farm weeds. Operation Weed Eradication calls on growers and partners to take action against troublesome weeds in their fields, through cultural practices, chemical control and enhanced diligence.

    Research by Stratus Ag shows that nearly 75 percent of growers nationwide are dealing with glyphosate-resistant weeds in their fields and today’s management practices are not sustainable for long-term control of problem weeds such as pigweed.

    “Our approach to on-farm eradication will uproot problem weeds and help secure a sustainable farming future that builds a successful legacy for seasons and generations to come,” said Scott Kay, Vice President U.S. Crop, BASF Agricultural Solutions. “Weed eradication will be a personalized, tailored journey for each grower with different start and end points. BASF will support growers with expertise and continuous innovation to support this journey.”

    Operation Weed Eradication takes a balanced approach of utilizing cultural practices such as conventional tillage, chemical control such as rotating chemistries, and eradication diligence such as hand weeding to help growers eradicating troublesome on-farm weeds.

    In the coming months, BASF will assemble a coalition of industry leaders, develop a specific eradication customer offering and launch an educational initiative to support its efforts with Operation Weed Eradication.To learn more, please visit

  • USDA Announces Details of Support Package for Farmers

    U.S. Secretary of Agriculture Sonny Perdue today announced further details of the $16 billion package aimed at supporting American agricultural producers while the Administration continues to work on free, fair, and reciprocal trade deals.

    In May, President Trump directed Secretary Perdue to craft a relief strategy in line with the estimated impacts of unjustified retaliatory tariffs on U.S. agricultural goods and other trade disruptions. The Market Facilitation Program (MFP), Food Purchase and Distribution Program (FPDP), and Agricultural Trade Promotion Program (ATP) will assist agricultural producers while President Trump works to address long-standing market access barriers.

    “China and other nations have not played by the rules for a long time, and President Trump is the first President to stand up to them and send a clear message that the United States will no longer tolerate unfair trade practices,” Secretary Perdue said. “The details we announced today ensure farmers will not stand alone in facing unjustified retaliatory tariffs while President Trump continues working to solidify better and stronger trade deals around the globe.

    “Our team at USDA reflected on what worked well and gathered feedback on last year’s program to make this one even stronger and more effective for farmers. Our farmers work hard, are the most productive in the world, and we aim to match their enthusiasm and patriotism as we support them,” Secretary Perdue added.

    Background:

    American farmers have dealt with unjustified retaliatory tariffs and decades of non-tariff trade disruptions, which have curtailed U.S. exports to China and other nations. Trade damages from such retaliation and market distortions have impacted a host of U.S. commodities. High tariffs disrupt normal marketing patterns, raising costs by forcing commodities to find new markets. Additionally, American goods shipped to China have been slowed from reaching market by unusually strict or cumbersome entry procedures, which affect the quality and marketability of perishable crops. These boost marketing costs and unfairly affect our producers. USDA is using a variety of programs to support American farmers, ranchers, and producers.

    Participating in the Trade Mitigation Call – Agriculture Secretary Sonny Perdue, USDA Chief Economist Rob Johansson, Under Secretary for Farm Production and Conservation Bill Northey, Acting Deputy Under Secretary for Food, Nutrition, and Consumer Services Brandon Lipps.

    Details of USDA’s Market Facilitation Program (MFP)

    MFP signup at local FSA offices will run from Monday, July 29 through Friday, December 6, 2019.

    Payments will be made by the Farm Service Agency (FSA) under the authority of the Commodity Credit Corporation (CCC) Charter Act to producers of alfalfa hay, barley, canola, corn, crambe, dried beans, dry peas, extra-long staple cotton, flaxseed, lentils, long grain and medium grain rice, millet, mustard seed, oats, peanuts, rapeseed, rye, safflower, sesame seed, small and large chickpeas, sorghum, soybeans, sunflower seed, temperate japonica rice, triticale, upland cotton, and wheat. MFP assistance for those non-specialty crops is based on a single county payment rate multiplied by a farm’s total plantings of MFP-eligible crops in aggregate in 2019. Those per-acre payments are not dependent on which of those crops are planted in 2019. A producer’s total payment-eligible plantings cannot exceed total 2018 plantings. County payment rates range from $15 to $150 per acre, depending on the impact of unjustified trade retaliation in that county.

    Dairy producers who were in business as of June 1, 2019, will receive a per hundredweight payment on production history, and hog producers will receive a payment based on the number of live hogs owned on a day selected by the producer between April 1 and May 15, 2019.

    MFP payments will also be made to producers of almonds, cranberries, cultivated ginseng, fresh grapes, fresh sweet cherries, hazelnuts, macadamia nuts, pecans, pistachios, and walnuts. Each specialty crop will receive a payment based on 2019 acres of fruit or nut bearing plants, or in the case of ginseng, based on harvested acres in 2019.

    Acreage of non-specialty crops and cover crops must be planted by August 1, 2019 to be considered eligible for MFP payments.

    The MFP rule and a related Notice of Funding Availability will be published in the Federal Register on July 29, 2019, when signup begins at local FSA offices. Per-acre non-specialty crop county payment rates, specialty crop payment rates, and livestock payment rates are all currently available on farmers.gov.

    MFP payments will be made in up-to three tranches, with the second and third tranches evaluated as market conditions and trade opportunities dictate. If conditions warrant, the second and third tranches will be made in November and early January, respectively. The first tranche will be comprised of the higher of either 50 percent of a producer’s calculated payment or $15 per acre, which may reduce potential payments to be made in tranches two or three. USDA will begin making first tranche payments in mid-to-late August.

    MFP payments are limited to a combined $250,000 for non-specialty crops per person or legal entity. MFP payments are also limited to a combined $250,000 for dairy and hog producers and a combined $250,000 for specialty crop producers. However, no applicant can receive more than $500,000. Eligible applicants must also have an average adjusted gross income (AGI) for tax years 2014, 2015, and 2016 of less than $900,000 or, 75 percent of the person’s or legal entity’s average AGI for tax years 2014, 2015, and 2016 must have been derived from farming and ranching. Applicants must also comply with the provisions of the Highly Erodible Land and Wetland Conservation regulations.

    Many producers were affected by natural disasters this spring, such as flooding, that kept them out of the field for extended periods of time. Producers who filed a prevented planting claim and planted an FSA-certified cover crop, with the potential to be harvested qualify for a $15 per acre payment. Acres that were never planted in 2019 are not eligible for an MFP payment.

    In June, H.R. 2157, the Additional Supplemental Appropriations for Disaster Relief Act of 2019 was signed into law by President Trump, requiring a change to the first round of MFP assistance provided in 2018. Producers previously deemed ineligible for MFP in 2018 because they had an average AGI level higher than $900,000 may now be eligible for 2018 MFP benefits. Those producers must be able to verify 75 percent or more of their average AGI was derived from farming and ranching to qualify. This supplemental MFP signup period will run parallel to the 2019 MFP signup, from July 29 through December 6, 2019.

    For more information on the MFP, visit www.farmers.gov/mfp or contact your local FSA office, which can be found at www.farmers.gov.

    Details of USDA’s Food Purchase and Distribution Program (FPDP)

    Additionally, CCC Charter Act authority will be used to implement an up to $1.4 billion FPDP through the Agricultural Marketing Service (AMS) to purchase surplus commodities affected by trade retaliation such as fruits, vegetables, some processed foods, beef, pork, lamb, poultry, and milk for distribution by the Food and Nutrition Service (FNS) to food banks, schools, and other outlets serving low-income individuals.

     

    Purchasing:

    AMS will buy affected products in four phases, starting after October 1, 2019 with deliveries beginning in January 2020. The products purchased can be adjusted between phases to accommodate changes due to: growing conditions; product availability; market conditions; trade negotiation status; and program capacity. AMS will purchase known commodities first. By purchasing in phases, procurements for commodities that have been sourced in the past can be purchased more quickly and included in the first phase.

    Vendor Outreach:

    To expand the AMS vendor pool and the ability to purchase new and existing products, AMS will ramp up its vendor outreach and registration efforts. AMS has also developed flyers on how the process works and how to become a vendor for distribution to industry groups and interested parties. Additionally, AMS will continue to host a series of free webinars describing the steps required to become a vendor. Stakeholders will have the opportunity to submit questions to be answered during the webinar. Recorded webinars are available to review by potential vendors, and staff will host periodic Question and Answer teleconferences to better explain the process.

    Product Specifications:

    AMS maintains purchase specifications for a variety of commodities, which ensure recipients receive the high-quality product they expect. AMS in collaboration with FNS regularly develops and revises specifications for new and enhanced products based on program requirements and requests. AMS will be prioritizing the development of those products impacted by unjustified retaliation. AMS will also work with industry groups to identify varieties and grades sold to China and other markets imposing retaliatory tariffs, such as premium apples, oranges, pears, and other products. AMS will develop or revise specifications to facilitate the purchase of these premium varieties in forms that meet the needs of FNS nutrition assistance programs.

    Outlets:

    The products discussed in this plan will be distributed to States for use in the network of food banks and food pantries that participate in The Emergency Feeding Assistance Program (TEFAP), elderly feeding programs such as the Commodity Supplemental Foods Program (CSFP), and tribes that operate the Food Distribution Program on Indian Reservations (FDPIR).

    These outlets are in addition to child nutrition programs such as the National School Lunch Program, which may also benefit from these purchases.

    Additionally, the rule provides flexibility for FNS to explore new channels of non-profit distribution of product, should the availability of distribution through traditional channels prove to be insufficient. FNS will offer products through traditional channels prior to consideration of new outlets.

    Distribution:

    AMS has coordinated with FNS, industry representatives, and other agency partners to determine necessary logistics for the purchase and distribution of each commodity, including trucking, inspection and audit requirements, and agency staffing.

    Details of USDA’s Agricultural Trade Promotion Program (ATP)

    USDA’s Foreign Agricultural Service (FAS) will administer the ATP under authorities of the CCC. The ATP will provide cost-share assistance to eligible U.S. organizations for activities such as consumer advertising, public relations, point-of-sale demonstrations, participation in trade fairs and exhibits, market research, and technical assistance. Last week, USDA awarded $100 million to 48 organizations through the ATP to help U.S. farmers and ranchers identify and access new export markets.

    The 48 recipients are among the cooperator organizations that applied for $200 million in ATP funds in 2018 that were awarded earlier this year. As part of a new round of support for farmers impacted by unjustified retaliation and trade disruption, those groups had the opportunity to be considered for additional support for their work to boost exports for U.S. agriculture, food, fish, and forestry products.

    Already, since the $200 million in assistance was announced in January, U.S. exporters have had significant success, including a trade mission to Pakistan that generated $10 million in projected 2019 sales of pulse crops, a new marketing program for Alaska seafood that led to more than $4 million in sales of salmon to Vietnam and Thailand, and a comprehensive marketing effort by the U.S. soybean industry that has increased exposure in more than 50 international markets. These funds will continue to generate sales and business for U.S. producers and exporters many times over as promotional activity continues for the next couple of years.

     

  • Soil Health Partnership Celebrates 5 Years of Growth and Collaboration

    The Soil Health Partnership (SHP) has been fostering transformation in agriculture through improved soil health since 2014. This year, SHP celebrates its fifth anniversary and the foundational collaborations that developed the program.

    SHP was founded by a diverse group of organizations with a shared vision of developing a farmer-led research network to measure the impacts of implementing soil health practices on working farms. The Nature Conservancy(TNC), Bayer, the Environmental Defense Fund(EDF), alongside the National Corn Growers Association (NCGA), came together to see this vision through. This program was based upon work supported by the National Resources Conservation Service, U.S Department of Agriculture.

    “We are proud of the collaboration led to SHP’s establishment. That collaboration has continued to grow and evolve with many partners, bringing dynamic perspectives to the table. We would not be where we are today without our founding partners sharing the vision, then seeing it through,” said SHP Executive Director Dr. Shefali Mehta.

    “Engaging with pragmatic, goal-focused groups like the Environmental Defense Fund and The Nature Conservancy, and bringing in agronomic expertise from Bayer, SHP was founded amongst a well-rounded, diverse group of organizations. We have accomplished a lot in five years thanks in large part to the support from our founding members and partner farmers,” said NCGA Vice President, Production and Sustainability, Nathan Fields. “The program is only just beginning. SHP is a priority to the NCGA board, and we can’t wait to see where we are in another five years and beyond.”

    The SHP network now spans across 16 states and includes over 100 partner organizations at the federal, state and county levels. SHP has grown from 17 active farms in 2014 to 220 active farms in 2019 and represents over 7,000 acres.

    SHP currently has a team of eight field managers that work alongside farmers in their region to design and implement experiments in fields across North America.

    “It is encouraging to see the vast number of farmers interested in investing in their land that they are proactively inviting SHP into their operations. We continue seeking new ways to diversify our offerings to enable farmers from a broad range of geographies and operations can be part of our program,” stated SHP Lead Scientist, Maria Bowman. “We credit our growth in large part to the energy and investment by the farmers in the SHP network. Our farmers believe and trust the work that we do, owning the data and the outcomes that are collected.”

    Mehta concludes, “We look forward to the future of continued collaboration, opportunities to learn and grow with other organizations, and working alongside a broad group of farmers as they ensure the sustainability of their farm operations. The foundation has been laid, and we are eager to see where the future takes SHP and soil health management for American farmers.”

    About the Soil Health Partnership

    The Soil Health Partnership is a farmer-led initiative that fosters transformation in agriculture through improved soil health. Administered by the National Corn Growers Association (NCGA), the partnership has more than 220 working farms enrolled in 16 states.

    About the National Corn Growers Association

    Founded in 1957, the National Corn Growers Association represents nearly 40,000 dues-paying corn farmers nationwide and the interests of more than 300,000 growers who contribute through corn checkoff programs in their states. NCGA and its 50 affiliated state associations and checkoff organizations work together to create and increase opportunities for their members and their industry.

  • New Studies Show Soil Health Practices Increase Farm Profitability

    Today, American Farmland Trust(AFT), the organization behind the national movement No Farms No Food®,is releasing four case studies that show that healthier soil on farmland brings economic benefits to farmers and environmental benefits to society. These case studies were developed in partnership with USDA’s Natural Resources Conservation Service (NRCS).

    AFT Water Initiative Director Dr. Michelle Perez, the lead researcher on the project, is unveiling the case studies at the Soil and Water Conservation Society annual conference today. The case studies were developed as part of a 2018 NRCS Conservation Innovation Grant (CIG) project, “Accelerating Soil Health Adoption by Quantifying Economic and Environmental Outcomes and Overcoming Barriers on Rented Lands,”and feature farms in California, Illinois, Ohio and New York.

    “Increasingly, we understand that better soil health – and specific practices aimed at building soil organic matter, fostering microbial life in the soil, reducing nutrient loss, and protecting soil from erosion – lead to higher net income for farming operations. These case studies contribute to the growing body of quantitative evidence that improving soil health increases farmer profitability,” said Dr. Perez.

    The two-page case studies focus on corn-soybean production in Illinois and Ohio, almond production in California and a diversified rotation (sweet corn, alfalfa, corn for silage or grain) in New York. The four farmers featured implemented soil health practices like no-till or strip-till, nutrient management, cover crops, compost, and mulching.

    “When it comes to conservation, producers have to make decisions based on what makes the most sense for their operations,” said NRCS Chief Matthew Lohr. “These case studies provide information on the economic benefits of using soil health management systems, demonstrating the value of adopting these systems.”

    With soil health management, producers can increase their yield, decrease their risk and input costs, and improve their profits, all while conserving our nation’s resources for the public at large, on their farms, in their watersheds, and beyond. Soil health management systems are good for farmers and for the public.

    “Increased implementation of soil health is critical to AFT’s holistic approach to saving the land that sustains us. Ensuring a sustainable future for this planet and our society requires we value the land, the practices on the land and the people who steward that land. AFT’s case studies showcase farmers who took the risk and are now enjoying the benefits of implementing practices that will support food production for a growing population while improving our environment and sequestering carbon. Farmers across the country can now embrace these practices and, with the help of staffers from AFT and our partner NRCS, put them into practice with greater confidence and profitability,” says John Piotti, AFT president and CEO.

    Highlights from the case studies include:

    • All four of the farmers profiled saw improved yields ranging from 2% to 22% that they attributed, in part, to their soil health practices. The average return on investment was 176% for the four farms in the study and ranged from 35% to 343%. The study accounted for other factors at play in increased yield such as improved seed varieties and increased seeding rates.
    • All four farmers saw improved water quality outcomes, both by witnessing reduced soil and water runoff and as estimated by USDA’s Nutrient Tracking Tool (NTT). NTT estimated that nitrogen reductions ranged from 40% to 98%, phosphorus reductions ranged from 74% to 92%; and sediment reductions ranged from 76% to 96% from specific fields in each farm.
    • All four farmers saw improved climate outcomes, as estimated by USDA’s COMET-Farm Tool. The tool estimated that total greenhouse gas emission reductions from specific fields in each farm ranged from 16% to 560%, corresponding to taking three-fourths of a car to 17 cars off the road.

    All four farmers have been implementing different soil health practices over different time frames and a variety of cropping systems. With these case studies and the ones that will be released in the fall, AFT is building a diverse library of on-farm examples of soil health investments that have led to economic gain.

    We hope that farmers who have been considering adding soil health practices to their operation will be able to use these case studies to approach their existing landowners, from whom they rent their land, to discuss sharing the risks and rewards of the soil health investments. We think farmers may be able to use the case studies with a new landlord to add new fields. Should that materialize, we hope farmers will also share the case studies with their bankers to secure additional financing for the farm expansion.

    Farmers across the country can reach out to their local NRCS and Soil and Water Conservation District staff to help them implement soil health practices on their farm. In the watersheds featured in the four case studies, farmers can reach out to both the local NRCS and SWCD staff as well as the four AFT authors of the case studies.

    We hope our conservation partners at NRCS, SWCD and Extension, plus our partners in the private sector, crop consultants, cover crop seed dealers, and strip-till equipment providers, use these case studies with their customers to help answer questions about the costs and benefits of adopting soil health practices.

    AFT’s first four case studies can be foundon AFT’s “Accelerating Soil Health” webpage.

    American Farmland Trust is the only national organization that takes a holistic approach to agriculture, focusing on the land itself, the agricultural practices used on that land, and the farmers and ranchers who do the work. AFT launched the conservation agriculture movement and continues to raise public awareness through our No Farms, No Foodmessage. Since our founding in 1980, AFT has helped permanently protect over 6.5 million acres of agricultural lands, advanced environmentally-sound farming practices on millions of additional acres and supported thousands of farm families.

    USDA’s Natural Resources Conservation Service (NRCS) mission is “Helping People Help the Land.” NRCS helps America’s farmers, ranchers and forest landowners conserve the nation’s soil, water, air and other natural resources. All programs are voluntary and offer science-based solutions that benefit both the landowner and the environment.

  • Weed Control in Lettuce

    Weed control in lettuce and other crops is a key issue this time of year. Purslane is particularly problematic and is adapted to warm conditions and can grow very rapidly especially during July and August. At times growers and PCA’s are disappointed with the efficacy of Kerb on this weed. Kerb is effective in controlling purslane but it is readily leached and, if applied at planting, it can be moved below the zone of germinating weed seeds with the germination water. For instance, 6-8 hours of sprinkler water (1.5 to 2.0 inches) are commonly applied in the first germination water which can move the Kerb below the upper 0.5 inch of soil which is the zone where the weed seeds germinate; the movement of Kerb with the germination water is particularly problematic on sandy soils. Prefar does not leach and thus provides most of the purslane control when the two materials are tank mixed (Figure 1). However, Prefar does not control shepherd’s purse or nightshades which can also be problematic in lettuce fields. Therefore, it would be advantageous to optimize the efficacy of Kerb to maximize the control of purslane as well as other weeds.

    In the desert, the use of delayed applications of Kerb has been used for many years. Due to the large amounts of water that are applied in their hot conditions, Kerb is applied in the 2nd or 3rd germination water, approximately 3-5 days following the first germination water, just prior to the emergence of the lettuce seedlings. This technique can also be utilized in the Salinas Valley. We have looked at this technique over the years and have found it to improve the efficacy of Kerb (Figure 2).  These data illustrate the loss of control of purslane by Kerb when applied before the 1st germination water, as well as the improvement in efficacy that results when applied following the 1st germination water. It also illustrates the role that Prefar plays in the control of purslane when the efficacy of Kerb is lost by leaching. It should be mentioned that the label states that the maximum amount of Kerb that can be applied through the sprinklers is 2.5 pints/A and the amount used in this trial was for experimental purposes only. Clearly there is benefit from applying the Kerb later in the 2nd or 3rd germination water, however, we observed that applying the Kerb at the end of the 1st germination water also provided improved efficacy of Kerb. Clearly, anything that helps to keep the Kerb in the top 0.5 inch of soil improves its efficacy.

    Here are some details that need to be considered regarding the application of Kerb later in the germination phase of the crop: There is a need to use an injection pump and tank. We have typically used a tank with a circulating mechanism to keep the Kerb in suspension while the injection was occurring. The material needs to be injected into the mainline in a location where proper mixing can occur before it begins to flow down the laterals. The most difficult issue that growers face is the compatibility of the injection with surrounding crops. This is probably the greatest challenge and must be carefully thought through before attempting an application.

    Another idea that we explored last year was the use of an additive to help retain the Kerb in the upper portion of the soil where it can be most active. However, we did not see improved efficacy in two 2018 trials (data not shown).

    Many growers now are now using drip irrigation to germinate lettuce. Grower may apply the same amount of water with drip germination as with sprinklers, but the movement of the water is different which affects a surface applied material differently. With this method of germination, there are a couple of interesting dynamics that occur: 1) Kerb is not pushed too deep by this germination method and effectively reduces weed populations whether injected into the germ water (currently not a registered method of application) or sprayed on the soil surface and activated by the drip germination water (Table 1); and 2) fewer weeds emerge with drip germination than with sprinklers, regardless of the herbicide program.

    Figure 1. On left: Kerb at 3.5 pints/A applied at planting; On right Kerb at 3.5 pints/A + Prefar at 1.0 gallon/A applied at planting. The main weed is common purslane which was not controlled by Kerb because it was pushed below the zone of germinating weed seeds by the germination water

     

    Figure 2. Efficacy of Kerb applied at 3.5 pints/A at planting or in the 3rd germination water; crop was romaine. Note that applying the Kerb after the first heavy application of germination water greatly improved its effectiveness.
