Available in PDF, EPUB and Kindle. Book excerpt: Degradation of soils continues at a pace that will eventually create a local, regional, or even global crisis when diminished soil resources collide with increasing climate variation. It's not too late to restore our soils to a more productive state by rediscovering the value of soil management, building on our well-established and ever-expanding scientific understanding of soils. Soil management concepts have been in place since the cultivation of crops, but we need to rediscover the principles that are linked together in effective soil management. This book is unique because of its treatment of soil management based on principles—the physical, chemical, and biological processes and how together they form the foundation for soil management processes that range from tillage to nutrient management. Whether new to soil science or needing a concise reference, readers will benefit from this book's ability to integrate the science of soils with management issues and long-term conservation efforts.

This book was released on 2017 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several agricultural land management practices, such as cover crops and tillage, can influence soil physical and hydraulic properties, soil health indicators and crop productivity. This study evaluated the influence of cover crops, tillage and perennial biofuel crops on soil physical and hydraulic properties. The objectives of this study included: (i) evaluate hydraulic properties for soils managed by cover crops and tillage, (ii) assess the influence of cover crops and tillage management on in situ water infiltration parameters, and (iii) evaluate thermal conductivity ([Lambda]), volumetric heat capacity (C[subscript v]) and thermal diffusivity (D) for soils managed by perennial biofuel and cover crops. Two field sites were used for the study; the first and second objectives were conducted at Lincoln University's Freeman Research Center while the third objective was conducted at University of Missouri Bradford Research Center. The cover crop grown at Freeman Research Center was Cereal rye (Secale cereal L.), while Cereal rye, Hairy vetch (Vicia villosa subsp. villosa) and Austrian winter pea (Pisum sativum subsp. arvense) were grown at Bradford Research Center. The perennial biofuel crops at Bradford Research Center included giant miscanthus (Miscanthus x gigantus J.M. Geef & Deuter ex Hodkinson & Renvoize) and switchgrass (Panicum vergatum L.). The tillage treatments at Freeman Research Center included tillage using a moldboard plow to a depth of 15 cm and no-till. The soil at Bradford Research Center was managed with no-till. Intact soil samples (76 by 76 mm) were collected for objectives one and three with samples taken in 2014 and 2015, respectively. Infiltrometers were used to measure infiltration rates for objective two during 2014 and 2015. The physically-based Parlange and Green-Ampt infiltration models were fit to estimate saturated hydraulic conductivity (K[subscript s]) and sorptivity (S) parameters. Results showed that bulk density values for tillage were 13% lower compared with no-till management right after tillage. At the 0-10 cm soil depth, water content was significantly higher at the 0.0 and -0.4 kPa pressures for tillage compared with no-till management, right after spring tillage. However, this effect did not persist over time probably due to soil consolidation after some rainfall events. Tillage improved coarse mesopores by 32% compared with no-till; and this effect resulted in 87% higher saturated hydraulic conductivity values in tillage compared with no-till management, right after spring tillage. Cover crops improved macropores by 24% compared with no cover crop; this can potentially increase water infiltration and reduce runoff. As a result of higher macroporosity, saturated hydraulic conductivity was higher in the cover crop compared with no cover crop management. This study demonstrated that the effects of tillage in improving some soil hydraulic properties may not persist over time. The Parlange and Green-Ampt model appeared to fit measured infiltration data well with coefficient of variation (r[superscript 2]) ranging from 0.92 to 0.99. The K[subscript s] parameter value estimated from the Parlange and Green-Ampt models in 2014 were 42% and 54% higher in no-till compared with tillage management, respectively. In 2015, the S parameter values estimated from the Parlange and Green-Ampt models were 82% and 90% higher in cover crop management compared to no cover crop management, respectively. This study showed that cover crops can improve water infiltration and may reduce water and nutrient runoff which can lead to enhanced agricultural productivity. Results of the third objective showed that perennial biofuel crops (giant miscanthus and switchgrass) had 11% higher C[subscript v] at saturation compared to row crops (cover crops and no cover crops). Cover crops compared to no cover crop had 18% higher volumetric water content at saturation and 26% higher soil organic carbon; this led to 13% higher C[subscript v] compared to no cover crops. Row crops had significantly higher [Lambda] and D compared to perennial biofuel crops. This study showed that perennial biofuel and cover crops can change soil thermal properties by reducing [Lambda] and D and increasing C[subscript v]; this indicates that these management systems can improve the ability of the soil to buffer against rapid heat change and better handle a more variable climate. Results from these studies showed that tillage may influence some soil properties temporarily; however, these influences may diminish over time. Cover crops can improve soil physical and hydraulic properties and soil health indicators and this can lead to improved productivity. However, longer-term studies are needed to evaluate these effects over time, especially with an increasingly changing climate.

Available in PDF, EPUB and Kindle. Book excerpt: This book will not serve as the "encyclopedia of cover crop management," but it’s close. The benefits of a wide range of individual cover crops and blends/mixes for specific agronomic crop rotations and geographic locations are included. Descriptions, photographs, and illustrations show how cover crops look in the field, including plant height, leaf architecture, and rooting patterns. Long term benefits are described for soil health, soil structure, water quality, nutrient contributions, soil biodiversity, air quality and climate change. In addition to the "whys" of cover crop use, the book includes details on the "hows:" how to choose cover crops for specific applications and locations; how (and when) to plant; how to manage and maintain the cover for maximum benefit; and how and when to terminate. Planting options include: drilling/planting between rows of an agronomic crop at planting time, or when the crop is short (i.e. corn in early June); "aerial" seeding with an airplane or high-clearance machine shortly before the crop reaches maturity; and drilling/planting immediately after harvest of the agronomic crop. Selected cover crops (blends) can help with pest and disease management. Cover crops are an economic input with an expected return on investment, similar to pesticides and fertilizer. As part of a continuous no-till system, cover crops provide long-term biological, chemical and structural benefits. The resulting increase in soil organic matter means the agronomic crop yields benefit from better water infiltration and water holding capacity, greater availability of nitrogen and other nutrients, deeper rooting, and increased soil microbial activity in the root zone.

Download or read book Tillage, Cover Crop and Nitrogen Fertilization Effects on Soil Microbial Carbon Dynamics Under Long-term Cotton Production written by Molefi Jacob Mpheshea and published by . This book was released on 2014 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective soil management requires a deeper understanding of how internal soil carbon (C) works. This is vital as cycling is tightly linked with nutrient cycling processes. This study evaluated the effect of agronomic practices including tillage (no-till and tilled), cover crops (no cover, hairy vetch - Vicia villosa L, and winter wheat - Triticum aestivum. L ) and different N fertilizer rates ( 0, 34 and 101 kg N per hectare ) on soil microbial C dynamics as measured by soil microbial biomass C (SMBC) along with soil microbial respiration over the 2013 cotton growing season at Jackson, West Tennessee. The study was set as split -split plot with N fertilizer rates as the whole plot, cover crops as the split plot and tillage as the split-split plot. Sampling was carried out four times; in June, July, September and October. Both SMBC and soil respiration responded similarly to the treatment factors. Early in the season, June and July, N fertilizer rate affected SMBC with 101N fertilizer rate having greater SMBC. In July, in addition to N fertilizer rate, tillage affected SMBC with tilled-vetch treatment at 34N and 101N fertilizer rate having a significantly greater levels of SMBC while soil respiration was greater under the no-till no cover treatment across all N fertilizer rates. However in September, tillage and cover crop affected SMBC and soil microbial respiration. The no-till no cover and no-till wheat treatments had greater SMBC and soil microbial respiration compared with no-till vetch at 0N and 34N fertilizer rate. At the end of the growing season prior to harvest, the no-till no cover treatment still had effect on soil microbial respiration while none of the treatment factors affected SMBC. Early in the season N fertilizer influences microbial activities while later in the season tillage and cover crop become the dominating factors. Overall the effects of N fertilizer, tillage and cover crops on these soil properties were season dependent.

Download or read book No-Tillage Agriculture written by Ronald E. Phillips and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: No-tillage cropping systems and concepts have evolved rapidly since the early 1960s and are attracting attention worldwide. The rapid growth and interest is associated with increasing pressures for food production from a fixed land resource base with degrading effects of erosion, soil compaction and other factors becoming more noticeable. Research programs have provided many answers and identified new technology needed for success of the no-tillage crop production system in the past two decades and this has resulted in a rapid rate of adoption. Farmers played an important role in the early stages· of development of the system and continue to play an important role in its improvement and rapid rate of adoption. This book provides an inventory and assessment of the principles involved in no-tillage concepts and addresses the application of the technology to practical production schemes. Selected authors and contributors have long been associated either in no-tillage research or application. They represent many disciplines interfacing with the complex interactions of soil, plant and environment. Personal obser vations by the authors in many geographic sectors of the world indicate the principles to be valid but application of the principles to be less uniform. The application of no-tillage principles requires considerable modification as variations in soil and/or climatic condi tions are encountered in different regions of the world.
