Determining Need for Phosphorus and Potassium Fertilizer
September 24, 2008
There are a couple of agronomic newsletters I read regularly: Ohio State University’s CORN and Purdue’s Chat ‘n Chew. In a recent edition of Chat ‘ n Chew, Camberato and Joern wrote an excellent article on reducing phosphorus and potassium fertilizer use to save money. The article discusses the differences between critical level, maintenance range and drawdown.
The very first place to start is with a good set of soil samples from your farm(s). Once you have your fields sampled or grid-sampled, you can make decisions based on science and not guessing. Full article here:
