Book Synopsis Soil Organic Matter in Temperate AgroecosystemsLong Term Experiments in North America by : Eldor A. Paul

Download or read book Soil Organic Matter in Temperate AgroecosystemsLong Term Experiments in North America written by Eldor A. Paul. This book was released on 2019-08-16. Available in PDF, EPUB and Kindle. Book excerpt: The presence - or absence - of soil organic matter (SOM) has important implications for agricultural productivity. It could also have significant implications for global climate due to its role as a source/sink of carbon. Therefore, it is important to understand the issues related to the accumulation or loss of SOM, to use what we have learned from experiments to make sound decisions about soil and crop management, and to test models and future concepts concerning SOM management. A database is included with the book, presenting tabular data for 34 sites in North America. Soil Organic Matter in Temperate Agroecosystems discusses all of these issues and more, answering such questions as:

Book Synopsis Management of Carbon Sequestration in Soil by : Rattan Lal

Download or read book Management of Carbon Sequestration in Soil written by Rattan Lal. This book was released on 2019-08-08. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the importance of soil processes in the global carbon cycle.Agricultural activities considered responsible for an increase in CO2 levels in our atmosphere include: deforestation, biomass burning, tillage and intensive cultivation, and drainage of wetlands.However, agriculture can also be a solution to the problem in which carbon can be removed from the atmosphere and permanently sequestered into the soil. Management of Carbon Sequestration in Soil highlights the importance of world soils as a sink for atmospheric carbon and discusses the impact of tillage, conservation reserve programs (CRP), management of grasslands and woodlands, and other soil and crop management and land use practices that lead to carbon sequestration.

Book Synopsis Evaluation of Soil Organic Matter Models by : David S. Powlson

Download or read book Evaluation of Soil Organic Matter Models written by David S. Powlson. This book was released on 2013-06-29. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter (SOM) represents a major pool of carbon within the biosphere, roughly twice than in atmospheric CO2. SOM models embody our best understanding of soil carbon dynamics and are needed to predict how global environmental change will influence soil carbon stocks. These models are also required for evaluating the likely effectiveness of different mitigation options. The first important step towards systematically evaluating the suitability of SOM models for these purposes is to test their simulations against real data. Since changes in SOM occur slowly, long-term datasets are required. This volume brings together leading SOM model developers and experimentalists to test SOM models using long-term datasets from diverse ecosystems, land uses and climatic zones within the temperate region.
