Ecological Principles of AgricultureDelmar, 2000 - 433 頁 Ecological Principles of Agriculture is a text for post-secondary students of agriculture and ecology. Its strength can be found in its versatility. Agricultural students with no prior coursework in ecology will find it invaluable as an introduction to ecological principles, while ecology students will gain insight into the practical application of these principles with respect to agriculture. This text will help readers understand the ecological processes inherent in any agricultural system as well as their implications in agricultural management. Without learning every type of agricultural practice (an impossible task), readers will come away with an understanding of how to apply these principles to agricultural design, management and problem-solving in very specific situations.
