Book excerpt: Loss of organic matter (OM) from soil through degradation can lead to decline in soil structure, depletion of plant nutrients, enhancing mineralization of organic compounds and contribute to climate change through the release of greenhouse gas emissions. To address this, it is important to identify and expand our current understanding of the management practices that ensure that the functions and services of soils in agricultural lands are maintained for the long-term. Sustainable agriculture aims to meet society's needs for food, feed, and fiber, while protecting natural resources and is primarily guided by the quality of and aims to maintain or improve health of soils. A management practice that directly benefits soil quality, through the enhancement of soil organic matter (SOM), is the use of organic matter amendments (OMA). OMAs are a group of organic materials that are rich in nutrients that can be recycled back to the soil and can have positive effects for improving soil conditions and properties, and are proposed as a climate change mitigation strategy. Through extensive field, laboratory studies, and advanced analytical techniques, I show the potential benefits of recycling organic matter amendments into agricultural soils in California. Three projects were established and make up the three chapters of my dissertation: the first project focused on how the application of two different types of composts in almond orchards influenced soil fertility and nutrient cycling. Main findings from this chapter show that the applications of these OMA were heavily influenced by soil texture. After two years of OMA application there was an improvement in soil fertility. The second chapter focused on how long-term application of biosolids in agricultural soils influences carbon content, specifically focusing on the importance of accounting for deep soil carbon in order to determine a soils climate change mitigation potential in three sites in northern California. Main findings show that application rate of biosolids is not a determining factor when it comes to carbon accounting, but management practices play a bigger role. Additionally, not accounting for deep soil carbon leads to an underestimation of carbon sequestration in biosolid amended soils. Chapter 3 builds off Chapter 2, and investigates the stability of this C and N by determining what pools in the soil they are in. These different pools will provide insight on how vulnerable these reservoirs are to management induced changes which can contribute to C and N losses. Overall findings show that long-term amended soils contribute increase carbon content associated to unprotected pools in surface soils where it is easier for microbes to mineralize. Carbon content in deeper soils show that the carbon is associated to physically protected and mineral associated pools, indicating this carbon to be more persistent. Overall, these findings show that site conditions, measurement methodology, and management practices influence the potential of OMA to be beneficial to soil fertility and climate beneficial.

Book Synopsis Soil Organic Matter in Sustainable Agriculture by : Fred Magdoff
Download or read book Soil Organic Matter in Sustainable Agriculture written by Fred Magdoff and published by CRC Press. This book was released on 2004-05-27 with total page 411 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recognition of the importance of soil organic matter (SOM) in soil health and quality is a major part of fostering a holistic, preventive approach to agricultural management. Students in agronomy, horticulture, and soil science need a textbook that emphasizes strategies for using SOM management in the prevention of chemical, biological, and physical problems. Soil Organic Matter in Sustainable Agriculture gathers key scientific reviews concerning issues that are critical for successful SOM management. This textbook contains evaluations of the types of organic soil constituents—organisms, fresh residues, and well-decomposed substances. It explores the beneficial effects of organic matter on soil and the various practices that enhance SOM. Chapters include an examination of the results of crop management practices on soil organisms, organic matter gains and losses, the significance of various SOM fractions, and the contributions of fungi and earthworms to soil quality and crop growth. Emphasizing the prevention of imbalances that lead to soil and crop problems, the text also explores the development of soils suppressive to plant diseases and pests, and relates SOM management to the supply of nutrients to crops. This book provides the essential scientific background and poses the challenging questions that students need to better understand SOM and develop improved soil and crop management systems.

Book Synopsis The Importance of Soil Organic Matter by : Alexandra Bot
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.

Book Synopsis Ecosystem Services and Carbon Sequestration in the Biosphere by : Rattan Lal
Download or read book Ecosystem Services and Carbon Sequestration in the Biosphere written by Rattan Lal and published by Springer Science & Business Media. This book was released on 2013-05-29 with total page 467 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological functions and human wellbeing depend on ecosystem services. Among the ecosystem services are provisional (food, feed, fuel, fiber), regulating (carbon sequestration, waste recycling, water cleansing), cultural (aesthetic, recreational, spiritual), and supporting services (soil formation, photosynthesis, nutrient cycling). Many relationships of various degree exist among ecosystem services. Thus, land use and soil management to enhance biospheric carbon sinks for carbon sequestration requires a comprehensive understanding on the effects on ecosystem services. Payments for ecosystem services including carbon pricing must address the relationship between carbon sequestration and ecosystem services to minimize risks of overshoot, and promote sustainable use of land-based carbon sinks for human wellbeing.

Book Synopsis Soil Remediation and Plants by : Khalid Hakeem
Download or read book Soil Remediation and Plants written by Khalid Hakeem and published by Academic Press. This book was released on 2014-08-29 with total page 771 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone’s health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil Examines the challenges and possibilities towards the various phytoremediation candidates Includes the latest research and ongoing progress in phytoremediation
