Fall Fertilizer Resources and How to Assess Your Program

Fall Fertilizer Resources and How to Assess Your Program

November 5, 2012

Soil temperatures across much of the state this week dropped below 50°F, the recommended threshold for fall nitrogen applications. Following are links to Extension information related to fall fertilizer management.

  • An article on Extension Educator Jenny Rees' blog, JenREESources's, looks at how growers can evaluate their nitrogen program by starting an on-farm research trial. It discusses how to establish a study, links to example studies and guides, and includes a list of educators and specialists who can help you design a trial. Rees writes "On-farm research may sound daunting, but today's equipment makes it easier than ever.  It does take a little extra time, but our farmers conducting on-farm research feel the value of knowing the results of a study on their own piece of ground make the effort worthwhile."

  • Soil Testing is Critical after a Drought Year to verify actual nutrient levels. Residual nitrate levels are expected to be high in very low-yielding dryland fields due tounused N fertilizer.  Levels may be higher than normal in sprinkler-irrigated fields, but lower than normal in furrow-irrigated fields.  Learn why soil testing will be so important this year before you plan your fertilizer purchase.
