  1. Registration and program agendas are available for two upcoming Nutrient Management Field Day events being hosted at OARDC Branch Stations. These programs provide the opportunity for a demonstration approach to Fertilizer Applicator Certification Training (FACT) while highlighting nutrient/water quality research being conducted at these locations. Information on nutrient sources of commercial fertilizer and manure are included.

    Details on the individual programs can be found at the links below:

    The number of individuals who have been trained for the Ohio Fertilizer Applicator Certification by Ohio State University Extension Agriculture and Natural Resources staff has reached 11,859 as of April 30, 2016. The ongoing training has generated a lot of positive response from farmers who attended. Requests have come in to make short review videos of key parts of the training available for review. The videos which range from 5 to 15 minutes in length have been posted to https://agcrops.osu.edu/video/fact-videos.

  3. Field days are important learning tools

    Currently 24 field days on a variety of topics are being planned by Agriculture and Natural Resource staff starting June 1 through the fall with locations throughout the state. A complete calendar of dates can be found at https://agcrops.osu.edu/events. Full agendas are still being developed and you will want to check back for registration information along with other details about a month prior to the date.

    In 2015, the Soil Fertility Lab at Ohio State started offering a third party evaluation of proprietary soil amendments and foliar applications aimed at improving the mineral nutrition and productivity of crops. This new service intends to provide timely and unbiased information on these products for farmers. In 2015, we tested submitted products from the following companies:

    The Tri-State Fertilizer Recommendations, published in 1995, provided a unified soil fertility framework between Michigan, Ohio and Indiana. These recommendations are based on, “field calibration and correlation studies that have been conducted over the past 40 years.” Although it was a collective scientific work, the extensive data that went into these recommendations were not systematically compiled and shared with the public.

    Ohio State is looking for farmer cooperators and crop consultants to help conduct on-farm field trials this year. Updating fertilizer recommendations is a major undertaking that will require a collective effort from numerous OSU extension personnel, crop consultants and farmer cooperators. We will be looking specifically at N, P, K and S in corn, soybean and wheat. We hope to collect data from a large number of farms across the state and determine economically-optimum fertilization rates to maximize farmer profitability.

  7. Streaming nitrogen on wheat
    Author(s): Ed Lentz, CCA , Author(s): Laura Lindsey , Author(s): Steve Culman

    In many southern Ohio locations wheat has already reached Feekes Growth Stage 5. This is an ideal time to apply spring nitrogen: plants will soon begin a rapid uptake of N and the potential for N loss will be reduced because of this larger demand. The northern part of the state has begun to green-up and N can be applied as soon as fields are fit for equipment.

  8. Winter Wheat
    Author(s): Ed Lentz, CCA , Author(s): Laura Lindsey

    For any N application the question to ask is, “When does the crop need N?” Wheat does not require large amounts of N until stem elongation/jointing (Feekes Growth Stage 6), which is the middle or the end of April depending on the location in the state and spring temperatures. Ohio research has shown no yield benefit from applications made prior to this time period. Soil organic matter and/or N applied at planting generally provide sufficient N for early growth until stem elongation.

  9. Regulations for manure and fertilizer application for applicators in the Western Lake Erie Basin need to be considered when making fertilizer applications in 2016 and future years. The legislation affects application of manure or granular fertilizers containing nitrogen and phosphorus. Define watersheds, which include the Western Basin of Lake Erie, need to comply with the regulations or face civil penalties. The civil penalties are effective as of 1/31/2016. The regulatory agency is the Ohio Department of Agriculture.

    Who must comply?

  10. Nutrient management plans developed to meet Natural Resource Conservation Service (NRCS) EQUIP program criteria can be developed by Certified Crop Advisors in the State of Ohio as a service to their farm clientele. Nutrient management plans take soil fertility recommendations one step further and start to assess the environmental concerns of field sites to nutrient runoff/loss via nutrient indexes plus assessing erosion and other resources concerns on the farm.
