Abstract

In this lesson, you will be able to describe the forms of nitrogen found in the soil. The nitrogen cycle and how nitrogen is lost in the environment will be thoroughly discussed. Forms of nitrogen utilized by the plant and the concept of nitrogen credits for such factors as legumes, manure, residual soil nitrogen, and irrigation water will be introduced.

[This lesson, as well as the other nine lessons in the Soils series, is taken from the "Soils Home Study Course," published in 1999 by the University of Nebraska Cooperative Extension.]
