Book excerpt: Abstract: Worldwide, peatlands cover approximately 2% of the Earth's surface, but contain an estimated 455 Pg of carbon (C), or 1/3 of the terrestrial C pool. Upon drainage and cultivation, progressive soil development strongly alters physical properties, and peat soils become tremendous sources of atmospheric carbon dioxide (CO2), nitrous oxide (N2O), and methane (CH4). No-till (NT) management has been shown to enhance soil physical characteristics and reduce the emission of GHG in mineral soils. The objectives of this study were to (i) assess the changes in soil physical properties with respect to drainage and land use, (ii) determine the effects of different tillage practices on physical properties of cultivated organic soils, (iii) compare soil moisture content, soil temperature, and GHG emission rates from mold board/disking, no-till, and bare treatments to determine organic matter decomposition, and (iv) measure the rate of subsidence associated with tillage. This report presents preliminary results of changes in soil physical properties, soil moisture content (SMC) and temperature, gaseous emissions, and subsidence rates observed following conversion from conventional plow tillage to no-till management in a Histosol of north central Ohio. Core samples and gas samples were obtained from several associated soil series in the muck area and from experimental plots managed with moldboard plow (MB), no-till (NT), or left bare (B). In general, Pb increased, jc decreased, and organic matter (OM), total carbon (TC), and total nitrogen (TN) concentrations decreased with drainage and land use change. Conversion of plow tillage to NT increased Pb from 0.52 Mg m−3 to 0.57 Mg m−3 , and decreased f[t] from 0.72 m3 m−3 to 0.70 m3 m−3. However, available water content (AWC) increased from 0.98 cm to 1.36 cm in the 0-10 cm layer, as did the proportion of micro- pores (0.1-15 um) with conversion to NT. Annually, SMC was higher in MB treatments (0.90 ± 0.032 kg kg−1) than NT (0.87 ± 0.024 kg kg−1) or B (0.83 ± 0.02 kg kg−1). Daily mean temperatures at 5 cm depth were significantly higher in B (16.9 ± 1.20C) and MB (16.2 ± 1.2 0C) compared to NT (15.9 ± 1.2 0C). The CO2 emissions were lower under NT (18.92 Mg CO2-C ha−1 yr−1) than MB (22.5 18.92 Mg CO2-C ha−1 yr−1) while N2O emissions were significantly higher from MB (96.9 kg N20-N ha−1 yr−1) than NT (35.8 kg N20-N ha−1 yr−1) plots. In all treatments, both CH4 uptake and CH4 emission occurred. Reduced soil organic matter mineralization with NT can limit subsidence and conserve peat soils for an additional 50 to 70 years over MB.

Book excerpt: The demand for food is expected to rise due to increases in world populations over the next decades. The use of heavy machinery to meet this demand for food is expected to increase as well. Additionally, soil compaction is recognized as a major concern in agriculture dependent on the use of heavy machinery. Soil compaction has been shown to negatively impact crop production, which may occur because of overuse of heavy machinery used in tillage operations, sowing, harvesting, and manure and fertilizer applications. Soil compaction also affects physical, chemical and biological processes occurring in the soil including the mineralization of soil organic carbon and nitrogen. Long-term experiments that include tillage and crop rotations are necessary to understand the impact of soil management practices on soil properties. Tillage practices (conventional tillage-CT; minimum tillage, MT; and no tillage, NT) and crop rotations (continuous corn-CC and corn-soybean-CS) effects on soil compaction and carbon and nitrogen were studied in the long-term Triplett-Van Doren plots which are part of the Ohio Agricultural Research Development Center (OARDC). These plots are experimental sites located in northeast Ohio (Wooster) and northwest Ohio (Hoytville).

Available in PDF, EPUB and Kindle. Book excerpt: World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management. Soil Processes and the Carbon Cycle describes soil processes and their effects on the global carbon cycle while relating soil properties to soil quality and potential and actual carbon reserves in the soil. In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.

Book excerpt: Recent changes in the Conservation Compliance Plans for farmers shows the need for improved information on the effective management of crop residues. Residue management requires an understanding of the crop, soil, and climate in which the farming system is located. In this volume, the strategies for effective residue management are described for each region of the country to provide a comparison of the regional differences. The chapters not only describe the knowledge in each region but also suggest some of the needed areas of research required to develop an improved understanding of the processes involved in effective residue management.

Available in PDF, EPUB and Kindle. Book excerpt: Nowadays the environmental sustainability of the cropping systems is increasingly requested by the consumers. Conventional tillage practices, totally turning over the soil between the vineyard rows, may cause erosion due to rain as well as structure destruction of the soil in the long term. Conservation tillage is a soil management technique, poorly widespread in Sardinia, allowing cover cropping between vineyard rows. Furthermore, this technique makes the canopy development control of herbage possible by cutting it up during specific phenological phases. Conservation tillage usually involves direct benefits to farmers such as increasing soil fertility as well as reductionof tillage costs, soil erosion and carbon dioxide (CO2) emissions in the atmosphere. This long term trial, during at least five years aims to assess the conservation tillage impact on chemical-physical soil characteristics in comparison with traditional tillage by evaluating the change of organic matter, C.E.C. and availability of major plant nutrients in the soil and to estimate their probable rise. The field plots are located in a 35% slope condition vineyard, showing massive erosion problem and organic matter low content. A split/plot design with four replications was set up, with the comparison between conservation and traditional tillage apart as main plots. Moreover, the effects of two different irrigation levels were evaluated in the subplots of each main plot. At the beginning of the trial (2011) a pedological survey was made. Three soil profiles were described and sampled along the field slope and soil sampling in each plot were made both to characterize the soil and to find the zero point. The soil chemical and physical characteristics were monitored through a second soil sampling made at the end of 2013. Conservation tillage caused increasing organic matter content and C.E.C. values. As for major plant nutrients in soil, results were more uncertain. Grapevine yield and quality parameters did not show any negative effect when passing from conventional to conservation tillage techniques. The trial provided a preliminary positive evaluation of conservation tillage. However, more years are required to confirm this trend.

Available in PDF, EPUB and Kindle. Book excerpt: This Encyclopedia of Agrophysics will provide up-to-date information on the physical properties and processes affecting the quality of the environment and plant production. It will be a "first-up" volume which will nicely complement the recently published Encyclopedia of Soil Science, (November 2007) which was published in the same series. In a single authoritative volume a collection of about 250 informative articles and ca 400 glossary terms covering all aspects of agrophysics will be presented. The authors will be renowned specialists in various aspects in agrophysics from a wide variety of countries. Agrophysics is important both for research and practical use not only in agriculture, but also in areas like environmental science, land reclamation, food processing etc. Agrophysics is a relatively new interdisciplinary field closely related to Agrochemistry, Agrobiology, Agroclimatology and Agroecology. Nowadays it has been fully accepted as an agricultural and environmental discipline. As such this Encyclopedia volume will be an indispensable working tool for scientists and practitioners from different disciplines, like agriculture, soil science, geosciences, environmental science, geography, and engineering.
