Fall nitrogen applications

It is not too early to start making plans for the next growing season. For some farmers, nitrogen (N) application in the fall is one of the many important decisions to make. Nitrogen is not only a large input in most corn farming operations, but it also represents an important input in terms of the environment.


Bion files patent on process to recover N fertilizer from waste

Bion Environmental Technologies, Inc., a provider of advanced livestock waste treatment technology, announced that it has filed a new patent application for a process that recovers a nitrogen-rich, natural, non-synthetic fertilizer product from a livestock waste stream.

Should you be applying lime?

Fall is an excellent time 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.


Decreasing loss when using urea

Selecting the right nitrogen source when fertilizing pastures and hayfields has always been important in nitrogen use efficiency. For many years we have had the option of using either urea or ammonium nitrate as the nitrogen source in our fertilizers. A basic recommendation was to use urea in spring, but use ammonium nitrate in summer and early fall. Urea was usually cheaper, but more prone to nitrogen loss due to volatilization, which occurs in hot weather with limited rainfall.

Revising fertilizer recommendations for corn, soybean and wheat

Ohio State is in the process of updating the Tri-State Recommendations, looking specifically at N, P and K in corn, soybean and wheat. This is a major undertaking that will require a collective effort from numerous extension personnel, crop consultants and farmer cooperators.
