Abstract

Anhydrous NH3 applied to soil is subject to chemical fixation by organic matter. A laboratory study was conducted to (i) determine the amount of N retained through chemical fixation of NH3 compared with the amount of NH4 fixed by clay, (ii) characterize the organic-matter-fixed NH3, and (iii) assess the biological availability of the fixed NH3. Results indicate that NH3-N newly fixed by organic matter occurs in forms that are less stabilized and more biologically available than the native soil N. -from Authors
