Book Description
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. Topics include: A broad range of soil microbial processes in terms of the importance of microbial heterogeneity Inputs by soil microorganisms into wheat-farming systems The importance of arbuscular mycorrhizal fungi in making nutrients more available to crops The benefits and environmental problems associated with the use of crops genetically modified with Bacillus thuringiensis The incorporation of soil ecological or microbial ecological theory into agricultural practice to improve agricultural productivity and sustainability Challenges in sustainable agricultural research and the need for coalescing new avenues of research in agriculture and soil ecology 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.

Book Description
This manual is designed for a four-day training course on climate-smart agriculture that would take the learner from the basics of climate science to the impacts of climate change and the linkages among climate, agriculture and food security. It contains four modules, each addressing a particular aspect and consisting of several sessions that are held either in plenary, as one group, or in smaller work groups. The content and structure of this manual has been developed and tested through fieldwork involving extension agents and agricultural producers in Zambia, Malawi and Viet Nam.

Book Description
The second edition of this book, first published in 1991 and intended for students and researchers, contains revised and updated material on the theory and practice of nitrogen fixation in tropical cropping systems. There are 15 chapters in 3 parts. Part I, Introduction, contains 5 chapters on tropical environments (climate, soils and cropping systems), nitrogen fixing organisms, the process of nitrogen fixation, assessment of the role of nitrogen fixation, and cycling of nitrogen in tropical cropping systems. Part II, Tropical crops and cropping systems, comprises 7 chapters on freeliving, root-associated and endophytic nitrogen fixing bacteria of cereal crops and grasses, cyanobacteria and Azolla as green manure for wetland rice, grain legumes, legumes as green manures and cover crops, forage legumes, understorey legumes and shade trees in plantation crops, and nitrogen fixing trees in agroforestry. Part III, optimizing nitrogen fixation, includes 3 chapters on environmental constraints, approaches to enhancement, and future impacts on nitrogen fixation in tropical agriculture. A list of common names and subject index are included.
