Nutrient Management Databases

Plant Nutrient Content Database
This database contains estimates of the nitrogen, phosphorus, and potassium content in plant biomass for many agricultural crops. This information is useful to nutrient management planners who need estimates of plant nutrient content to develop nutrient management plans. It becomes particularly valuable when nutrients are applied in quantities that are a function of the nutrient content of plant biomass.
