  1. A Microsoft Excel spreadsheet has been developed to support nutrient management education programs provided by Ohio State University Extension and for users who want to generate their own recommendation or compare recommendations provided to them to the Tri-State Fertilizer Recommendations for Corn, Soybeans, Wheat, and Alfalfa, 2020. The spreadsheet is designed to be compatible with Excel version, Excel 1997-2003 or later.

    Many individuals have already applied lime this fall; however, lime can still be applied before planting next spring. It is important to test soil pH and determine whether any lime needs to be applied for future crops. Proper soil pH is important for nutrient availability, herbicide activity, and crop development. For most soils, additional lime is not needed every year. Consider these points before liming your fields:

    NutrientStar, an independent evaluator of nutrient management tools, has just released results testing the performance of two web-based tools that provide customized corn nitrogen fertilizer rates: Adapt-N and Climate FieldView. Both tools are available for farmers in Ohio to use for a fee.

    NutrientStar conducted 61 trials over 3 years evaluating Adapt-N and 21 trials over 2 years evaluating FieldView in Ohio. A summary of findings is presented below.

    Summary of Performance of Adapt-N and FieldView Compared to Farmer Normal Practices.

    Tissue analysis can play an important role in determining if corn and soybean are getting adequate nutrition. Tissue samples can be pulled at various stages of development, but one of the most common times is when crops enter the reproductive stages (R1). Prior to R1, corn and soybean are in a rapid growth phase with very high nutrient uptake over several weeks. Sampling at R1 allows us to determine if their nutrient needs are being met, or if a particular nutrient is deficient. But how important is it that the tissue sampling happen right at flowering?

    Ohio is now seeing full implementation of Ohio’s Agricultural Fertilizer Applicator Certification regulation. The regulation was result of Senate Bill 150, which can be found at http://codes.ohio.gov/orc/905.322 and http://codes.ohio.gov/orc/905.321. The 2014 regulation required farmers to complete a fertilizer certification program if they applied fertilizer to more than 50 acres of land in agricultural production primarily for sale.
