Download or read book Structure and Organic Matter Storage in Agricultural Soils written by M.R. Carter and published by CRC Press. This book was released on 2020-12-17 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils comprise the largest pool of terrestrial carbon and therefore are an important component of carbon storage in the biosphere-atmosphere system. Structure and Organic Matter Storage in Agricultural Soils explores the mechanisms and processes involved in the storage and sequestration of carbon in soils. Focusing on agricultural soils - from tropical to semi-arid types - this new book provides an in-depth look at structure, aggregation, and organic matter retention in world soils. The first two sections of the book introduce readers to the basic issues and scientific concepts, including soil structure, underlying mechanisms and processes, and the importance of agroecosystems as carbon regulators. The third section provides detailed discussions of soil aggregation and organic matter storage under various climates, soil types, and soil management practices. The fourth section addresses current strategies for enhancing organic matter storage in soil, modelling techniques, and measurement methods. Throughout the book, the importance of the soil structure-organic matter storage relationship is emphasized. Anyone involved in soil science, agriculture, agronomy, plant science, or greenhouse gas and global change studies should understand this relationship. Structure and Organic Matter Storage in Agricultural Soils provides an ideal source of information not only on the soil structure-storage relationship itself, but also on key research efforts and direct applications related to the storage of organic matter in agricultural soils.

Available in PDF, EPUB and Kindle. Book excerpt: The Future of Soil Carbon: Its Conservation and Formation provides readers with an integrative approach to understanding the important role of organic carbon in soil functioning and fertility. Terrestrial interactions between SOC and complex human-natural systems require new fundamental and applied research into regional and global SOC budgets. This book provides new and synthesized information on the dynamics of SOC in the terrestrial environment. In addition to rigorous state-of-the art on soil science, the book also provides strategies to avoid risks of soil carbon losses.

Download or read book Structure and Functioning of Seminatural Meadows written by M. Rychnovská and published by Elsevier. This book was released on 2012-12-02 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: Twelve years' analysis of natural grassland and experimentally managed meadows have produced this unique set of data on the structures and physiological functions of primary producers, consumers and decomposers. Obtained during the 1973-1985 Ecosystem Study on Highland Meadows in Czechoslovakia, such original information is rare in scientific literature. The aim of the study was to define the functioning of these grasslands and their changes under different impact of man, and to examine the ecological function of those ecosystems in the intensively managed catchment area. Hence, this book contains deep analyses of soil microorganisms, their functions in decomposition and soil forming processes - leading to the evaluation of the whole carbon cycle - as well as dealing with nitrogen pathways in the experimental plots - resulting in precise determination of the full nitrogen cycle. Procedures used in practical agriculture, such as cutting, fertilization and renovation, have also been applied, producing evaluations from both ecological and economical view-points. The book's integrated ecosystem approach to grasslands, its deep professional analyses in each section, along with the synthesis on each particular level and across all levels, renders it an invaluable, informative text, comprising extensive figures and tables and a substantial bibliography of world-wide sources.

Download or read book Bioactive Compounds in Agricultural Soils written by Lech Wojciech Szajdak and published by Springer. This book was released on 2016-11-02 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume looks at the impact that different cropping systems and tillage have on soil’s biologically active substances. It considers how phytotoxins accumulate and can inhibit the development of cultivated plants. Coverage explores the continuous cropping of rye, crop rotation, no tillage, and conventional tillage. It offers a comprehensive, comparative approach to allelopathic plant-soil interactions. The authors focus on free and bounded biologically active substances such as amino acids, auxins, humic and fulvic acids, transient radicals, and enzymes in light sand soils fertilized with different mineral and organic fertilizers. The chapters address fundamental questions relevant to the environmental challenges we face today and will deal with in the future. The results involve asking basic questions motivated by soil's chemical and biochemical processes. The answers will lead to the improvement of the quality of soil’s organic matter, which, in turn, can lead to increased crop yields. Readers will come to understand the relationship between ecological processes and environmental change on individual levels of biocomplexity as well as on systems in their entirety. The title is ideal for students and teachers for laboratory practical classes. Soil scientists, biochemists, chemists, plant ecophysiologists, “Natural Products” organic chemists, and other environmental scientists and specialists will also find it useful.
Download or read book The Importance of Soil Organic Matter written by Alexandra Bot and published by Food & Agriculture Org.. This book was released on 2005 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil organic matter - the product of on-site biological decomposition - affects the chemical and physical properties of the soil and its overall health. Its composition and breakdown rate affect: the soil structure and porosity; the water infiltration rate and moisture holding capacity of soils; the diversity and biological activity of soil organisms; and plant nutrient availability. This document concentrates on the organic matter dynamics of cropping soils and discusses the circumstances that deplete organic matter and their negative outcomes. It then moves on to more proactive solutions. It reviews a "basket" of practices in order to show how they can increase organic matter content and discusses the land and cropping benefits that then accrue.--Publisher's description.
