Dry fertilizers can be safely and quickly applied in the fall. Some tillage will help ensure nutrients are placed below the soil surface. This will help reduce stratification and lower the concentration of dissolved P in the runoff water.
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.
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.
Last Wedneday at a Homeland Security and Governmental Affairs subcommittee on Regulatory Affairs and Federal Management hearing entitled, “Examining the Use of Agency Regulatory Guidance,” U.S. Senator Joni Ernst (R-Iowa) expressed concerns raised by Iowans over the Department of Labor’s Occupational Safety and Health Administration’s (OSHA) recently issued guidance that negatively impacts anhydrous ammonia retailers.
Yale University scientists may have cracked a part of the chemical code for one of the most basic, yet mysterious, processes in the natural world — nature’s ability to transform nitrogen from the air into usable nitrogen compounds.
As this year’s grain harvest winds down, thoughts may already be on nitrogen needs for next year's crop. A Montana State University Extension web-based decision tool to help calculate optimal nitrogen fertilizer rates for small grains has been updated and is ready for use.
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.
