Tillage for Sustainable Cropping is a state of the art examination of diverse tillage systems and tillage induced edaphic changes and their implications for soil productivity and the environment. It provides a rational framework for tillage systems that takes soil and climatic characteristics and the availability of other edaphic inputs into consideration. This well referenced volume also examines soil sustainability in terms of pollution greenhouse gases water contamination growing production demands and soil degradation and looks at the way crops respond to tillage techniques in terms of weed growth root growth crop yields and more. 195 pp.

" Intensive Cropping combines the basic and applied aspects of soil water, nutrients, and energy management to help you optimize your crop yields and maximize the use of these inputs in intensively farmed regions. In Intensive Cropping, you will explore the need for extreme farming and related concerns and concepts, including: vCreating methods to conserve water by reducing runoff deep seepage, and evaporation losses v Supplementing irrigation with surface and groundwater vUnderstanding the process of water uptake and the effects on root dynamics and water use v Reducing gaseous, leaching, and erosion losses in your fields vUsing combinations of organic manures, crop residues, chemical fertilizers, and biofertilizers for soil maintenance vImplementing conventional and emerging tillage systems, such as conservation tillage for improving soil quality vExamining case studies of contrasting edaphic requirements of rice-wheat systems."
