Download or read book Soil Management written by Jerry L. Hatfield and published by John Wiley & Sons. This book was released on 2020-01-22 with total page 432 pages. 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.

Download or read book Cover Crops and Sustainable Agriculture written by Rafiq Islam and published by CRC Press. This book was released on 2021-06-16 with total page 327 pages. 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 Using Cover Crop Mixtures to Reduce Nitrate Leaching and Supply Nitrogen to Corn written by Charles White and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture faces two great sustainability challenges: the ability to provide nutrition for a growing world population and the ability to increase ecosystem services that maintain clean air, clean water, and other benefits to humanity. Planting cover crops is one management practice that can contribute towards realizing the goal of increasing ecosystem services. However, to provide multiple ecosystem services and to manage tradeoffs between services, cover crops will need to be intensively managed. This dissertation develops models and tools that can support the adaptive management of cover crops to reduce nitrate (NO3-) leaching and supply nitrogen (N) to a subsequent corn crop through N mineralized from decomposing residues. Models were developed from a wide range of cover crop experiments carried out over 14 site years that included 39 different treatments of cover crop mixtures and monocultures composed from 18 different species of grasses, brassicas, and legumes. A model for potential NO3- leaching under cover crop mixtures indicated that increasing total non-legume biomass N content (sum of fall and spring N contents) of a cover crop reduced leaching at a rate of -0.91 kg NO3--N kg-1 biomass N, up to a threshold of 51 kg N ha-1 total non-legume biomass N, above which increasing non-legume biomass N had no further effect. In a model for relative corn yield following cover crop mixtures, relative yield was negatively related to fall and spring cover crop biomass carbon to nitrogen (C:N) ratios and positively related to soil carbon (C) concentration. In another model, the response of unfertilized corn yields to a previous cover crop, relative to fallow conditions, increased with cover crop biomass N content and a decreasing biomass C:N ratio, with regression models that were different for winterkilled and winterhardy cover crops due to differences between the cover crop types in the length of decomposition and the synchrony between decomposition and corn N demand. For these models to be applicable in an adaptive management process, farmers need to be able to rapidly and inexpensively measure cover crop biomass N content. A handheld NDVI meter was able to accurately predict biomass N content in fall and spring for a wide range of cover crop types. Coupling between C and N cycles also needs to be considered in relation to predicting N mineralization from decomposing cover crops and others forms of organic matter. In models that represent soil organic C saturation, regulation of the C humification efficiency by C saturation level affected a coupled N mineralization model in a way that depended on the model structure used. Under some model structures, N mineralization increases as the C saturation level increases, which could affect the extent to which cover crop residues supply N to subsequent crops. Collectively, these models provide a foundation that can support the adaptive management of cover crops to provide N-related ecosystem services.

Download or read book Nitrogen Fixing Winter Cover Crops and Production Risk written by James A. Larson and published by . This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Winter legumes can substitute for applied nitrogen fertilization of corn. Stochastic dominance was used to order net revenues from legume and applied nitrogen alternatives. Stochastic dominance orderings indicate that systems combining vetch with low applied nitrogen fertilization (50 and 100 pounds/acre, respectively) were risk inefficient. By contrast, vetch and 150 pounds/acre applied nitrogen maximized expected net revenue and was risk efficient for a wide range of risk-averse and risk-seeking behavior. Farmers with these risk attitudes may not reduce applied nitrogen if they switch to a vetch cover. Extremely risk-averse or risk-seeking farmers would not prefer winter legumes.
