Available in PDF, EPUB and Kindle. Book excerpt: This title includes a number of Open Access chapters. This important compilation presents an in-depth view spanning past values and practices, present understandings, and potential futures, and covering a range of concrete case studies on sustainable development of organic agriculture. The book explores the very different facets of organic and sustainable agriculture. Part I of this book delves into the ways that people have approached organic agriculture in sociological, scientific, and economic terms. Part II looks ahead to the future of organic agriculture, presenting opportunities for further progress. Part III consists of an extensive bibliography chronologically developing the progress of organic and sustainable agriculture over two thousand years. The book Studies the cultural dimension of organic consumption Presents how sustainable agriculture can reduce and mitigate the impact of climate change on crop production Looks at the impact of agriculture on both famine and rural poverty in an ecofriendly and socially inclusive manner Examines six of the oldest grain-crop-based organic comparison experiments in the US, looking at the environmental and economic outcomes from organic agroecosystems, to both producers and policymakers Reviews the role of experimentation and innovation in developing sustainable organic agriculture Looks at the challenges of organic farmers Discusses ways to ensure sustainability and resilience of farming Looks at ways to change the mindset of farmers especially in traditional farming communities Explores the development of organic and sustainable agriculture through more than 500 years, ending with the early twenty-first century. Altogether, the chapters provide a nuanced look at the development of organic and sustainable agriculture, with the conclusion that organic is not enough to be sustainable.

Book excerpt: Soil Organic Matter: Its Nature, Its Role in Soil Formation and in Soil Fertility focuses on the contributions of soil organic matter in soil formation and fertility, including weathering, decomposition, and synthesis of humus substances. The publication first elaborates on the main stages in the history of soil humus study and ideas on the composition of soil organic matter and nature of humus substances. Discussions focus on organic substances of individual nature, strictly humus substances in soil organic matter, and humus substances as a complex of high molecular- weight compounds. The text then examines the biochemistry of humus formation, including the role of physical, chemical, and biological factors, origin of humus substances, possible participation of lignin in the formation of humus substances, and the role of oxidizing enzymes in the synthesis of humus substances. The manuscript takes a look at the importance of organic matter in soil formation and soil fertility and the natural factors of humus formation. Topics include the role of organic matter in the weathering and decomposition of soil minerals; role of organic matter in the formation of soil structure; effect of organic matter on the growth and development of plants; and influence of chemical and physicochemical soil properties on humus formation. The publication is a dependable source material for readers interested in the influence of soil organic matter in soil formation and fertility.
