Available in PDF, EPUB and Kindle. Book excerpt: Carbon stabilization involves to capturing carbon from the atmosphere and fix it in the forms soil organic carbon stock for a long period of time, it will be present to escape as a greenhouse gas in the form of carbon dioxide. Soil carbon storage is an important ecosystem service, resulting from interactions of several ecological processes. This process is primarily mediated by plants through photosynthesis, with carbon stored in the form of soil organic carbon. Soil carbon levels have reduced over decades of conversion of pristine ecosystems into agriculture landscape, which now offers the opportunity to store carbon from air into the soil. Carbon stabilization into the agricultural soils is a novel approach of research and offers promising reduction in the atmospheric carbon dioxide levels. This book brings together all aspects of soil carbon sequestration and stabilization, with a special focus on diversity of microorganisms and management practices of soil in agricultural systems. It discusses the role of ecosystem functioning, recent and future prospects, soil microbial ecological studies, rhizosphere microflora, and organic matter in soil carbon stabilization. It also explores carbon transformation in soil, biological management and its genetics, microbial transformation of soil carbon, plant growth promoting rhizobacteria (PGPRs), and their role in sustainable agriculture. The book offers a spectrum of ideas of new technological inventions and fundamentals of soil sustainability. It will be suitable for teachers, researchers, and policymakers, undergraduate and graduate students of soil science, soil microbiology, agronomy, ecology, and environmental sciences

Available in PDF, EPUB and Kindle. Book excerpt: This series is dedicated to serving the growing community of scholars and practitioners concerned with the principles and applications of environmental management. Each volume will be a thorough treatment of a specific topic of importance for proper management practices. A fundamental objective of these books is to help the reader discern and implement human's stewardship of our environment and the world's renewable resources. For we must strive to understand the relationship between humankind and nature, act to bring harmony to it, and nurture an environment that is both stable and productive. These objectives have often eluded us because the pursuit of other individual and societal goals has diverted us from a course of living in balance with the environment. At times, therefore, the environmental manager may have to exert restrictive control, which is usually best applied to humans, not nature. Attempts to alter or harness nature have often failed or backfired, as exemplified by the results of imprudent use of herbicides, fertilizers, water, and other agents. Each book in this series will shed light on the fundamental and applied aspects of environmental management. It is hoped that each will help solve a practical and serious environmental problem.

Download or read book Controls of Microbially Mediated Soil Carbon Cycling written by Samuel Evan Barnett and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil dwelling microorganisms are essential components of numerous ecosystem processes and biogeochemical cycles. In particular, they are important actors in terrestrial carbon cycling, producing and turning over soil organic matter. Microbially mediated soil carbon cycling can be influenced by environmental conditions, with soil organic matter dynamics and carbon fate varying across biomes. Drastic alterations to soil habitat conditions brought about through anthropogenic changes to land-use (e.g. agriculture) can greatly influence these processes. However, we are limited in our understanding of how land-use regimes and other environmental conditions control microbially mediated soil carbon cycling. I took three approaches to explore this relationship. First, I examined how bacterial community assembly and composition differed across cropland, old-field, and forest soils. I found that homogeneous selection, whereby selection pressure causes bacterial communities to be more phylogenetically similar to each other than expected by random assembly from a metacommunity, was the dominant bacterial community assembly process across all three land-use types. However, I also found that land-use interacted with soil pH to drive the balance between stochastic and deterministic assembly processes. This result indicates a mechanism by which microbial communities may develop differently across land-use regimes. Second, I examined the overall organic matter turnover across land-use regimes and the identity of the bacterial taxa actively involved in this carbon processing. I found that the dynamics of organic matter turnover and the active bacterial populations involved were distinct across land-use regimes. From these patterns I developed a conceptual model explaining how initial microbial biomass, which is impacted by land-use, may control bacterial activities in organic matter turnover. Finally, I examined the genomic basis of bacterial life history strategies, specifically the copiotroph-oligotroph continuum. Life history strategy can explain both bacterial activity in soil carbon cycling and bacterial response to environmental change. I found that the abundance of transcription factor genes and genes encoding a secretion signal peptide were both genomic signatures of the copiotroph-oligotroph continuum. These signatures can be used to classify diverse microbes based on their life history strategy and may further explain the biological drivers of these strategies. I also developed a toolkit, MetaSIPSim, that simulates metagenomic DNA-stable isotope probing datasets. Such datasets can be used to improve metagenomic DNA-stable isotope probing methodologies and analyses, which in turn can be used to link microbial genes and genomes to in situ carbon cycling activity. Overall, this work advances our knowledge of, and ability to study the ecological and biological controls of bacterially mediated soil carbon cycling.

Available in PDF, EPUB and Kindle. Book excerpt: Unknown to most people, there are innumerable microbial species that accomplish vital ecosystem functions while residing in a suspended state in the troposphere or resting on crop canopies. These microbial species, if utilized properly, can improve agriculture. At the same time, harmful microbes can also devastate crops easily. This new book, Microbiology of the Agricultural Sky, explores a number of microbes present in the agrarian sky and details their identities, roles in nature, and usefulness to crops as well as other biotic factors. The volume first provides an introduction that details the historical aspects of microbes relating to their discovery and identification of their role in agrarian ecosystems. The book then gives detailed explanations of microbes in the atmosphere, with information on the general distribution, spread distance, and intercontinental migration of microbes in the atmosphere. It discusses aeolian dust microbes above agrarian regions and the role of aerial microbes in nutrient dynamics. The book also explains the functions of microbes that reside on crop canopies and the importance of the plant‘s phyllosphere. It looks at microbial flora and how a region‘s bio-geochemical functions affect crops. Also discussed is the role of aerial microbes in inducing epidemics and pandemics among different crops. The final chapter details farm procedures that can be adopted in the outfield and in animal houses and how they impact atmospheric microbes. Key features: Highlights the relevance of the agrarian sky and its microbial component, detailing the wide range of functions that microbes accomplish in the aerospace Presents a timeline of discoveries about aeromicrobiology and the agrarian sky Discusses aerial microbes on crop canopies and their influence on plant pathogens, including beneficial nutrients, need for crop protection, etc. Looks at the microbiology of the agrarian sky and the spread of crop diseases locally and via the intercontinental migration of microbes Discusses farm procedures and their impact on microbes in the troposphere and the agricultural fields beneath it This first-of-its-kind book provides extensive information on microorganisms that can be traced in the agrarian sky and their relevance to agriculture.
