Download or read book Encyclopedia of Agrophysics written by Jan Gliński and published by Springer Science & Business Media. This book was released on 2011-06-07 with total page 1075 pages. 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.

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.

This book was released on 2006 with total page 270 pages. Available in PDF, EPUB and Kindle. 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.
