Description

Nutrient management guidelines in Iowa and other states use the words “manure nutrient availability” when suggesting manure application rates to supply nutrients needed by crops. People are sometimes confused about the meaning of the word “availability.” In fact, manure management guidelines across the region vary in the exact use and this contributes to confusion. Interestingly, Webster’s Ninth New Collegiate Dictionary includes “plant” and “nitrogen” in the definition of “available.” One definition is “present or ready for immediate use”, and another definition is “present in such chemical or physical form as to be usable (as by a plant) <~ nitrogen> …” So, why is there confusion?
