| Abstract: | Nitrogen in the soil is continually undergoing transformation, changing in form and availability. All phases of the cycle through which this element passes must be considered in attempting to explain nitrogen balances, losses or gains. Processed such as ammonification, nitrosofication, nitrification, nitrogen fixation, and denitrification need study in this respect. Nitrogen transformations and losses in soils have been investigated extensively in various countries and exhaustive reviews of a general nature1),8,,9),15) are available. |
