Available in PDF, EPUB and Kindle. Book excerpt: Intensive tillage requires high energy input and may be detrimental to the environment. There is a need to develop decision support tools to assist farmers in determining optimum tillage intensity for high yields. Previous studies developed quantitative indices that related tilth conditions to yield. The indices, however, proved to be inadequate and sometimes inconsistent. Thus, a three-part research project was carried out from 1998 to 2000 to quantify seedbed condition following tillage and to explain subsequent variation in corn (Zea mays L) yield. Conventional and spatial statistics were used to study the effects of bulk density, penetration resistance and soil moisture content on and biomass at the V2 growth stage (the corn growth stage when the collar of the second leaf has fully developed), and grain yield. A soil condition index was developed and it combined soil physical properties into a single value that was related to yield using regression methods. The soil condition index gave promising results for prediction of early season plant biomass, but was not helpful in predicting grain yield. Confounding of weather conditions made it difficult to determine the true functional relationship between soil tilth and crop yield. Yield and soil map overlays revealed spatial patterns that would have otherwise been aggregated' if only conventional statistical methods were used. With careful experimental design, the impact of weather and other sources of experimental error in tillage trials could be minimized. The research project provided a framework for future experiments focused on quantifying soil tilth.

Book Synopsis Tillage Effects on Soil Physical Properties, Weed Seed Distribution in Soil and Shifts in Species by : Claudio Purissimo
Download or read book Tillage Effects on Soil Physical Properties, Weed Seed Distribution in Soil and Shifts in Species written by Claudio Purissimo and published by . This book was released on 1996 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: A tillage experiment established in the fall of 1986 in a Thorp silt loam was used to conduct a study on how long-term tillage systems affect soil strength, bulk density, soil water characteristics, weed seed distribution in soil, and shifts in species. The experiment included a corn-soybean rotation with both crop grown each year. For this study, only the corn crop was considered. The tillage systems for corn consisted of fall chisel plow followed by spring disk and field cultivate (CDFC), spring field cultivate (FC) and no-tillage (NT) prior to planting corn. Tillage system did not significantly influence soil strength in the deeper soil zones. Compared to CDFC and FC, long-term NT resulted in higher soil density at depths close to the soil surface, as confirmed by its higher soil strength and bulk density. Nonetheless, higher water holding capacity and volumetric water content were observed with NT. The soil seed bank contained four monocotyledonous and twenty dicotyledonous weed species. Across all tillage systems, the high number of dicotyledonous species observed in the soil seed bank were not expressed as flora present late in the season. Conversely, a consistent relationship between giant foxtail presence in the soil seed bank and observed weed flora was found. The vertical distribution in the weed seed bank showed a distinct relationship between giant foxtail seeds and shallow depths with NT. On a volume basis, 51% of the giant foxtail seeds were concentrated in the top 1 cm of soil with NT, 78% in the top 2 cm, and 92% in the top 3 cm. Concentration of seeds near soil surface with NT is related to the absence of soil disturbance. With CDFC, giant foxtail seeds were uniformly distributed in depth range studied, which may be attributed to the physical displacement of the seeds by the action of tillage implements. High giant foxtail population was significantly associated with the NT system, with more than 85% of the total weed population in the untreated check plots being represented by that species. Weed seed bank was a reliable indicator of the giant foxtail infestations late in the season, but was unreliable for the other species.
Book Synopsis Soil Management and Climate Change by : Maria Angeles Munoz
Download or read book Soil Management and Climate Change written by Maria Angeles Munoz and published by Academic Press. This book was released on 2017-10-16 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil Management and Climate Change: Effects on Organic Carbon, Nitrogen Dynamics, and Greenhouse Gas Emissions provides a state of the art overview of recent findings and future research challenges regarding physical, chemical and biological processes controlling soil carbon, nitrogen dynamic and greenhouse gas emissions from soils. This book is for students and academics in soil science and environmental science, land managers, public administrators and legislators, and will increase understanding of organic matter preservation in soil and mitigation of greenhouse gas emissions. Given the central role soil plays on the global carbon (C) and nitrogen (N) cycles and its impact on greenhouse gas emissions, there is an urgent need to increase our common understanding about sources, mechanisms and processes that regulate organic matter mineralization and stabilization, and to identify those management practices and processes which mitigate greenhouse gas emissions, helping increase organic matter stabilization with suitable supplies of available N. Provides the latest findings about soil organic matter stabilization and greenhouse gas emissions Covers the effect of practices and management on soil organic matter stabilization Includes information for readers to select the most suitable management practices to increase soil organic matter stabilization
