Beschreibung:
Derived from a 2009 ESA symposium, this book brings together soil ecologists, microbial ecologists, and agroecologists working globally to demonstrate how research in soil ecology can contribute to the long-term sustainability of agricultural systems. This book provides an up-to-date synthesis of ecological theory and practice in agroecosystem theory and function. It integrates comparative and interdisciplinary research on soil ecology and microbial ecology theory into agricultural practice to improve agricultural productivity and sustainability. Many studies are referenced in order to help the reader understand concepts.
Soil ecology and agroecosystem studies: A dynamic and diverse world. Manipulation of beneficial microorganisms in crop rhizospheres. The influence of heterogeneity on soil microbial processes in agroecosystems: Theory, evidence, and opportunities. Soil food webs in agricultural ecosystems. Community composition of soil organisms under different wheat farming systems. The biological basis for nitrogen management in agroecosystems. The contribution of arbuscular mycorrhizal fungi to the success or failure of agricultural practices. Effects of the cultivation of genetically modified Bt crops on nontarget soil organisms. Maize legume relay intercrops in Malawi: Meeting short- and long-term sustainability goals. Making soil biodiversity matter for agriculture: Ecosystem services and challenges.
