Agroecology: Ecological Processes in Sustainable AgricultureCRC Press, 1998 - 357 σελίδες Agroecology is defined as the application of ecological concepts and p rinciples to the design and management of sustainable agroecosystems. This definitive book provides the theoretical and conceptual framework for the study and analysis of agroecosystems. The author builds upon the understanding of the complex factors of the environment as they a ffect agricultural crops and animals. It examines concepts at a system s level, focusing on interactions and interrelationships on the popula tion, community, and ecosystem levels. Informative case studies demon strate how ecology can be applied to agriculture. Each chapter conclud es with questions to ensure a complete understanding of the informatio n. Recommended readings are provided for those interested in advanced study. |
