While soil ecologists continue to be on the forefront of research on biodiversity and ecosystem function, there are few interdisciplinary studies that incorporate ecological knowledge into sustainable land management practices. Conventional, high fossil-fuel input-based agricultural systems can reduce soil biodiversity, alter soil community structure and nutrient cycling, and lead to greater dependence on energy-intensive practices.
Microbial Ecology in Sustainable Agroecosystems 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. The book identifies five key areas of research that can be combined to support and direct sustainable land management practices: agriculture, biodiversity, ecosystem services, integrated soil ecology research, and policy.
The contributors range from long-time ecological researchers to graduate students and early career scientists, representing a wide spectrum of experience, ages, diversity, and research interests in this area. They cover the diversity and complexity of microbial activity and interactions in soil systems and the many ways in which microorganisms may be manipulated and managed to improve the functions of crop rhizospheres and thereby maximize crop yields and overall productivity. These recommendations can be used to direct and influence agricultural and environmental policy and guide future research in sustainable agricultural systems management.
