Effect of ammonia on soil properties and relevance to soil and water quality
Anhydrous ammonia (AA) has been known to have deleterious effects on the surface structure of soil through various mechanisms, such as reduction of organic matter, slaking of soil and killing of beneficial soil flora and fauna. The purpose of this study is to investigate changes in soil physical, chemical and biological properties resulting from the application of AA that may have implications for sustainable productivity of the soil by increasing the potential for soil erosion and the loss of phosphorous and other nutrients from cropland. The study was focused on the effect of AA on soil structure and nutrient levels, particularly the level of phosphorous. Consideration was given to the eventual field application of the findings of the study by carefully selecting soil types that will enhance the transfer of technology.
