Описание книги

Understanding the contributions of fixed-N and other rotation effects is essential in reducing energy use and pollution potential of inorganic fertilizer usage and to understand the process by which a legume benefits a non-legume grown in rotation. Two rotation cycles were evaluated to separate the fixed- N from other rotation effects of soybean and cowpea, natural fallow and maize on subsequent maize. The experiment was laid out in a split-plot design. The legumes fixed between 16 and 50 kg N/ha of their total N and had an estimated N contribution to soil ranging from -22 to 3 kg N/ha depending on the ratio of N derived from atmosphere and N harvest index. On average, maize following legumes had higher grain yield of 1.3-fold and NFRVs of 28 kg/ha compared with maize after maize. The correlations between soil microbial C and N, and crop yield indicate that these soil quality parameters can be used to predict yield. This book is essential for graduate students and...
