This rules of thumb poster has been developed to provide a general understanding of nitrogen (N) in soil and in the different organic inputs such as legume cover crops, compost, and manure. All numbers provided are approximate.
The fate of nitrogen in soil is influenced considerably by site-specific variables such as soil type, soil structure, growing region, weather conditions, soil biology, and rotations. The rules of thumb are general in nature. Growers should consider their unique situation when interpreting the organic nitrogen rules of thumb.
