Advances in Organic Farming: Agronomic Soil Management Practices focuses on the integrated interactions between soil-plant-microbe-environment elements in a functioning ecosystem. It explains sustainable nutrient management under organic farming and agriculture, with chapters focusing on the role of nutrient management in sustaining global ecosystems, the remediation of polluted soils, conservation practices, degradation of pollutants, biofertilizers and biopesticides, critical biogeochemical cycles, potential responses for current and impending environmental change, and other critical factors. Organic farming is both challenging and exciting, as its practice of'feeding the soil, not the plant provides opportunity to better understand why some growing methods are preferred over others. In the simplest terms, organic growing is based on maintaining a living soil with a diverse population of micro and macro soil organisms. Organic matter (OM) is maintained in the soil through the addition of compost, animal manure, green manures and the avoidance of excess mechanization. - Presents a comprehensive overview of recent advances and new developments in the field OF research within a relevant theoretical framework - Highlights the scope of the inexpensive and improved management practices - Focuses on the role of nutrient management in sustaining the ecosystems

This new book summarizes the up-to-date knowledge on different fractions of amino acids in soil, input of amino acids to soil from both dead and living plant material, different extraction procedures done in order to release amino acids from soil, and the distribution of amino acids into soil profiles in regards to quality and quantity. In addition, this book provides detailed information on the quality and quantity of differently bounded fractions of amino acids in soil, land use and its effect on availability of amino acids and the description of proteolysis in soil and the release of amino acids by these processes.

Soil Microbiology and Biochemsitry enconmpasses the broad spectrum of soil organisms and the dynamic processes carried on by them, including ecological relationships in the biota, the dynamics of the carbon and nitrogen cycles, and microbe-driven reactions involving sulfu, phosphorous, and metals. This reference source will prove invaluable to anyone involved in the study of agricultural and nonagricultural soils.This book provideda process-oriented approach on nutrient cycling and fundamental soil processes for students who are studying soil microbiology and biochemistryan up-to-date assessment of the diverse systems affected by soil organisms for researchers in the fields of agronomy, environmental quality, and natural sciencesthe application of molecular biology to soil organisms, mathematic modeling of soil processes, a supplementary reading list, and a glossary.
