Soil Carbon Storage: Modulators, Mechanisms and Modeling takes a novel approach to the issue of soil carbon storage by considering soil C sequestration as a function of the interaction between biotic (e.g. microbes and plants) and abiotic (climate, soil types, management practices) modulators as a key driver of soil C. These modulators are central to C balance through their processing of C from both plant inputs and native soil organic matter. This book considers this concept in the light of state-of-the-art methodologies that elucidate these interactions and increase our understanding of a vitally important, but poorly characterized component of the global C cycle. The book provides soil scientists with a comprehensive, mechanistic, quantitative and predictive understanding of soil carbon storage. It presents a new framework that can be included in predictive models and management practices for better prediction and enhanced C storage in soils. Identifies management practices to enhance storage of soil C under different agro-ecosystems, soil types and climatic conditions Provides novel conceptual frameworks of biotic (especially microbial) and abiotic data to improve prediction of simulation model at plot to global scale Advances the conceptual framework needed to support robust predictive models and sustainable land management practices

Soil carbon stock, including soil organic carbon (SOC) and soil inorganic carbon(SIC) stock, is the largest pool in terrestrial ecosystem, and only a small changein storage has an impact on level of greenhouse gases in the atmosphere. Therefore,soil carbon sequestration is believed to be one of the cost-effective ways toreduce greenhouse gas concentrations in the atmosphere and mitigate globalgreenhouse effects. This study calculates soil carbon storages and evaluates soilorganic storage change in the course of industrialization and urbanization inYangtze Delta region, China, based on the data of the Second National Soil Survey(1982-1985) and the Multi-Purpose Regional Geochemical Survey (2002-2005), which may provide baseline dada for research into regional carbon sequestration/source effect and carbon circulation.

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

Soil carbon sequestration can play a strategic role in controlling the increase of CO2 in the atmosphere and thereby help mitigate climatic change. There are scientific opportunities to increase the capacity of soils to store carbon and remove it from circulation for longer periods of time. The vast areas of degraded and desertified lands throughout the world offer great potential for the sequestration of very large quantities of carbon. If credits are to be bought and sold for carbon storage, quick and inexpensive instruments and methods will be needed to monitor and verify that carbon is actually being added and maintained in soils. Large-scale soil carbon sequestration projects pose economic and social problems that need to be explored. This book focuses on scientific and implementation issues that need to be addressed in order to advance the discipline of carbon sequestration from theory to reality. The main issues discussed in the book are broad and cover aspects of basic science, monitoring, and implementation. The opportunity to restore productivity of degraded lands through carbon sequestration is examined in detail. This book will be of special interest to professionals in agronomy, soil science, and climatology.

Decreasing trends of organic matter and plant-available nutrients in arable soils, other negative consequences of fertilizer inputs and frequent tillage call for newer techniques in agriculture, one such technique which has attracted considerable interest is microbial management. Microbial biomass is a small active fraction of the soil organic matter which turns over very rapidly, and holds a large pool of plant-available nutrients. It acts as a source and a sink of nutrients and is responsive to several agricultural practices. Soil organic carbon (SOC) has also been identified as a factor that is important to soil fertility as well as for the environment because of huge carbon sequestration potential of the soils. Present study was undertaken to evaluate the influence of applications of straw and chemical fertilizer on the soil microbial biomass, available nutrient pools and crop growth under reduced tillage, dryland conditions. The major hypothesis tested in this study was that the management practices which can increase the size of active soil organic pool can enhance the nutrient supply rate and hence crop growth in drylands under reduced tillage cultivation

As the largest terrestrial carbon pool, changes in soil carbon pools in response to climate change or management practices have the potential to significantly impact atmospheric CO2 concentrations. This dissertation examines the effects of climate change and two management strategies on soil carbon pools in order to understand how soil carbon storage might change under these conditions. Changes in soil carbon concentrations were studied in a Danish heath/grassland exposed to elevated CO2, summer drought, and warming. Soil carbon was observed to increase significantly over the course of 8 years in the presence of elevated CO2, regardless of the addition of warming or drought treatments. Soil carbon pools at this site are therefore likely to serve as a negative feedback to increasing atmospheric CO2 concentrations. To examine how management strategies could take advantage of the potential for soils to be used as a carbon sequestration tool, this dissertation also investigated the effects of two types of management practices on soil carbon dynamics. In a Pacific Northwest Douglas-fir stand, deep soil carbon storage was shown to increase when competing vegetation was not controlled, presumably due to deeper Douglas-fir rooting in response to competition for more shallow soil moisture reserves. In an incubation study, applying olivine with the goal of increasing soil pH and capturing CO2 resulted in decreased decomposition of organic matter compared to the application of agricultural lime. There was no difference in CO2 flux between the olivine amended and control samples, whereas the CO2 flux from the limed samples was 221% higher than the control. The application of olivine also increased soil pH to a level sufficient to overcome aluminum toxicity. The use of olivine as an alternative to lime would therefore significantly reduce agricultural CO2 emissions. The results of this dissertation suggest that not only is there potential for increasing soil carbon stocks to serve as a negative feedback to rising atmospheric CO2 concentrations, but that an opportunity also exists to design management practices that utilize soils as a climate change mitigation tool.

In order to build consensus on methods to measure and model soil carbon stocks and stock changes, the Steering Committee of the Livestock Environmental Assessment and Performance (LEAP) Partnership mandated a task force to develop this scoping analysis and pave the way towards the formation of the LEAP Tecnical Advisory Group on soil carbon stock changes. Soil carbon sequestration and storage in grasslands offers a significant potential to compensate for GHG emissions from livestock, but the lack of consensus on the appropriate methodologies to account for soil carbon stock changes hinders robust and standardized assessments. In this report, we reviewed several published soil organic carbon (SOC) models, and evaluated their aptitude to combine them with life cycle assessments (LCAs). Among contentious issues, the most relevant are: a) the lack of universal models, b) the uneven data availability, comparability and quality between countries and regions, and c) the difficulty to match measurable SOC fractions with those determined by the models. Taking this into account, a tiered approach is proposed, according to the availability of original data to run the models. The use of IPCC carbon (C) accounting system appears to be the simplest approach suitable to countries with scarcity of original C data. Conversely, more complex models such as Century (Parton 1987, 1988) or Roth C (Smith 1998) are likely to perform better and give less uncertainty when original input data are easily available.

Urbanization drastically alters the ecosystems structure and functions, disrupts cycling of C and other elements along with water. It alters the energy balance and influences climate at local, regional and global scales. In 2008, urban population exceeded the rural population. In 2050, 70% of the world population will live in urban centers. The number of megacities (10 million inhabitants) increased from three in 1975 to 19 in 2007, and is projected to be 27 in 2025. Rapid urbanization is altering the ecosystem C budget. Yet, urban ecosystems have a large C sink capacity in soils and biota. Judicious planning and effective management can enhance C pool in urban ecosystems, and off-set some of the anthropogenic emissions. Principal components with regards to C sequestration include home lawns and turfs, urban forests, green roofs, park and recreational/sports facilities and urban agriculture.

Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil sampling and preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues. In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.

Soils offer the potential to sequester large quantities of carbon from the atmosphere for decades to millennia and so may ameliorate the anthropogenic influence of fossil fuel release. However changes in climate can drastically affect the soil's ability to store carbon through changes mineralogy on time scales of human interest. It is essential to understand the major controls on soil carbon dynamics before we attempt to manage sequestration to control atmospheric CO2 buildup. Models of the terrestrial carbon cycle often use clay content to parameterize soil carbon turnover. Evidence from volcanic soils suggests that soil mineralogy is a major control on a soil's ability to store carbon, because different types of minerals have widely varying abilities to physically and chemically isolate soil organic matter from decomposition, however volcanic soils represent only a small percentage of the earth's soils. The relationship between precipitation and soil carbon storage is also complex and poorly constrained. Significantly, precipitation changes predicted as a result of atmospheric CO2 doubling include increased rainfall throughout California. We utilized 14C, [delta]13C, and the total organic carbon, iron, and aluminum contents to address the question of the importance of mineralogy and climate on carbon storage in soils formed on a globally representative parent material. The California coastal terraces, formed over the last 500 thousand years as a result of tectonic uplift and sea level change, provide a natural laboratory to examine the effect of mineralogy and climate on carbon storage. We have focused on two terraces sequences, one near Eureka and one near Santa Cruz. Within each set of terraces only soil mineral development varies; all other variables are constant (rainfall, plant systems, and soil parent material, and land management). Annual precipitation at Eureka is twice that at Santa Cruz, allowing us to examine its role in the transport of organic carbon to deeper horizons. The objective of the study is to improve the understanding of soil carbon storage and derive a set of proxies for organic carbon turnover for terrestrial carbon cycle models.

Soil organic carbon affects soil fertility and agricultural production, and organic C storage can also mitigate increasing atmospheric CO2 concentrations on decadal time scales or longer. However, soil organic C storage is dependent on climatic conditions, especially temperature and precipitation, and changes in these parameters associated with climate change can act as feedback mechanisms to atmospheric CO2 concentrations. The objective of this study is to evaluate regional organic carbon abundance in northern India across orographically-limited precipitation regimes. We hypothesized that the existence of a soil organic carbon (SOC) gradient corresponding to these bioclimatic barriers, a result of this large precipitation and assumed vegetation discrepancy. Samples were collected from the Kulu Lesser Himalaya, Lahul Himalaya, and Zanskar and measured for SOC/TN inventory as well as?14C and d13C analysis of soil organic matter (SOM). Average annual carbon accumulation and C turnover time were estimated for selected soil chronosequences, and results varied widely among the areas investigated. It was revealed that soil organic C stocks in the Indian Himalaya are sensitive to precipitation, C3 vegetation has been consistently dominant up to ~6ka B.P., and rates of accumulation and turnover are influenced greatly by variations in climate, vegetation, and topography. Examining the distribution of soil organic carbon stock can be useful in helping to predict the potential effects of warming and precipitation on C storage in this region.
