Inhalt:
Organic wastes are traditionally applied to land to recover their fertilizer value, but the microbial turnover of such organic matter in soil is often out of phase with the requirements of growing plants. Therefore, nutrients may be lost and may even act as potential pollutants of water and air, posing a particular challenge to agricultural and environmental engineers.This book addresses both experimental and modeling methodology under the main headings of nitrogen and carbon transformations, gaseous losses, chemical means of controlling nitrification, and nitrate leaching. The articles ar
