The book deals with several aspects of soil erosion, focusing on its connection with the agricultural world. Chapters’ topics are various, ranging from irrigation practices to soil nutrient, land use changes or tillage methodologies. The book is subdivided into fourteen chapters, sorted in four sections, grouping different facets of the topic: introductive case studies, erosion management in vineyards, soil erosion issue in dry environments, and erosion control practices. Certainly, due to the extent of the subject, the book is not a comprehensive collection of soil erosion studies, but it aims to supply a sound set of scientific works, concerning the topic. It analyzes different facets of the issue, with various methodologies, and offers a wide series of case studies, solutions, practices, or suggestions to properly face soil erosion and, moreover, may provide new ideas and starting points for future researches.

"I've seen the Sudan, traveled in South and Central America and been all over Europe, but I've never seen what I've been able to see on this tour [of the Loess Plateau, China]." -Ed Skidmore, soil scientist, Wind Erosion Research Unit of the Agricultural Research Service, USDA, Manhattan, Kansas Overpopulation is at the core of most environmental problems. The impacts of continued growth-with world population reaching 6 billion in October 1999-are felt in most parts of the world. China, the most populous nation, illustrates many of the pivotal problems-and solutions. Although China faces the same effects of overpopulation as the rest of the world, it still feeds over a billion people on a tillable area that allows about one tenth of a hectare per person. The country's efforts to tie together soil and water conservation, dryland farming, and economic development have been largely successful. Soil Erosion and Dryland Farming explores these trials and the lessons learned from them. Copublished with the Soil and Water Conservation Society, this exhaustive text consists of the rewritten proceedings from the Society's conference held in Yangling, Shaanxi, China. It covers dryland farming systems and soil water management, environmental quality and sustainability, and erosion control techniques as they relate primarily to Mainland China. With additional global examples and a balance between conceptual and applied studies, it covers some of the most progressive work in soil erosion control and dryland farming from around the world. Soil exposure while land lies fallow is one of the greatest risks in dryland farming. New procedures and kinds of tillage help control erosion and improve water intake. Soil Erosion and Dryland Farming presents these techniques and technologies to give you a forward-looking perspective into the field, as well as the larger problem of tailoring food production to sustain the population.

Impacts Of Soil Management Practices On Soil Fertility In Potato Based Cropping Systems In The Bolivian Andean Highlands written by Javier Aguilera Alcón and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2010 with Cropping systems categories.
Due to changes in climate and socioeconomic developments, current soil management practices in the Bolivian Andean Highlands may be increasing soil degradation thereby threatening food security. A study was established in four representative communities during the 2006-09 growing seasons to identify an integrated soil management strategy that may help to improve soil fertility and productivity by increasing soil organic matter. Soil samples collected from fields of different lengths of cropping (LC) and fallow (LF) showed that LC decreased and LF increased total (TOC) and active soil organic C (AOC), and total (TN), inorganic (TIN) and active soil N (AIN). Field trials established with combinations of soil inorganic fertilizers (SIF) and local and alternative soil organic fertilizers (i.e., cow and sheep manure, household compost and a biofertilizer) revealed that the cow and sheep manure combined with SIF significantly affected soil properties, such as pH, soil test P, TN, TIN and TOC, soil water content and bulk density and significantly increased the production of potato (Solanum tuberosum L.) and a subsequent quinoa (Chenopodium quinoa Willd.) crop. Results of testing a portable field method to assess N status of potato plant tissue suggest that use of the Cardy nitrate-N meter may have some promise for tissue testing for potato in the Andean highlands of Bolivia, where access to soil and plant tissue testing services is limited.
