Book 1997shows how these can be applied in order to assess the nitrogen status in crops and to improve nitrogen nutrition through optimized N fertilization management. In this way economic benefits can be obtained, while at the same time preventing detrimental effects on the environment. The main agricultura

Maize and Sorghumity of N soil mineralization in summer, the importance of animal manure inputs in many situations, and the uncertainty of the potential production as a consequence of variation in the intensity of summer drought, make prediction of the optimum N application rate very difficult.
