Download or read book Subsoil Management Techniques written by Bobby A. Stewart and published by CRC Press. This book was released on 1994-10-12 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The principles and practice of deep tillage techniques have often failed to provide long-term, sustainable improvements of the soil for crop production. The book reviews alternative approaches to overcoming subsoil problems. These approaches involve reduced disturbance of the soil, but still provide substantial and sustainable soil improvements. Chapters 1 through 4 discuss the use of minimum tillage, bed farming, mole drainage, and slotting to overcome adverse subsoil conditions. Chapter 5 examines the options available for management of subsoil acidity. The next chapter provides an understanding of the processes involved in stress transmission and compaction under farm trafficking. The last chapter explains the critical role of soil microorganisms in providing long-term biological stabilization and improvements of soil. This reference brings together the latest research information on these subsoil amelioration techniques.
Download or read book Assessment and Governance of Sustainable Soil Management written by Katharina Helming and published by MDPI. This book was released on 2020-01-24 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: The role of soils for achieving the Sustainable Development Goals is multifarious. Soils are the essential basis for food and biomass provision in support of food security (SDG 2) and energy security (SDG 7). Soil carbon sequestration is paramount for climate action (SDG 13). Soil-mediated water purification and retention, nutrient and matter cycling, and soils habitat functions are essential for maintaining ecosystem services and biodiversity (SDG 15). Healthy soils perform well in all these functions simultaneously. However, the globally increasing demand for food, fiber, and bio-based products poses massive challenges to soil health. Minimizing trade-offs between biomass production and soil health requires systemic approaches to assessment and governance of sustainable soil management in agriculture and food systems. It provides interdisciplinary insights into key questions: What are the impacts of agricultural management practices on sustainability targets in specific geophysical and socio-economic contexts? What are the opportunities and risks of future trends such as climate change, digitalization, and emerging technologies for soil management and soil health? How can institutions and governance instruments be improved to enable decision makers to take action on sustainable soil management? The book was initiated in the frame of the National German research program ‘BonaRes—Soil as a sustainable resource for the bioeconomy’, and it is meant to trigger interdisciplinary thinking.

Download or read book Ecosystems of Disturbed Ground written by L.R. Walker and published by Elsevier. This book was released on 1999-12-17 with total page 881 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human population inexorably grows, its cumulative impact on the Earth's resources is hard to ignore. The ability of the Earth to support more humans is dependent on the ability of humans to manage natural resources wisely. Because disturbance alters resource levels, effective management requires understanding of the ecology of disturbance. This book is the first to take a global approach to the description of both natural and anthropogenic disturbance regimes that physically impact the ground. Natural disturbances such as erosion, volcanoes, wind, herbivory, flooding and drought plus anthropogenic disturbances such as foresty, grazing, mining, urbanization and military actions are considered. Both disturbance impacts and the biotic recovery are addressed as well as the interactions of different types of disturbance. Other chapters cover processes that are important to the understanding of disturbance of all types including soil processes, nutrient cycles, primary productivity, succession, animal behaviour and competition. Humans react to disturbances by avoiding, exacerbating, or restoring them or by passing environmental legislation. All of these issues are covered in this book.Managers need better predictive models and robust data-collections that help determine both site-specfic and generalized responses to disturbance. Multiple disturbances have a complex effect on both physical and biotic processes as they interact. This book provides a wealth of detail about the process of disturbance and recovery as well as a synthesis of the current state of knowledge about disturbance theory, with extensive documentation.

Download or read book Subsoil Constraints for Crop Production written by Teogenes Senna de Oliveira and published by Springer Nature. This book was released on 2022-08-03 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will address the major subsoil physical and chemical constraints and their implications to crop production; Plant growth is often restricted by adverse physical and chemical properties of subsoils yet these limitations are not revealed by testing surface soils and hence their significance in crop management is often overlooked. The major constraints can be physical or chemical. Physical limitations such as poor/nil subsoil structure, sandy subsoils that do not provide adequate water or gravelly subsoils and, etc. On the other hand, chemical constraints include acidity/alkalinity, high extractable Al or Mn, low nutrient availability, salts, boron toxicity and pyritic subsoils. Some of these constraints are inherent properties of the soil profile while others are induced by crop and soil management practices. This aim of this book is to define the constraints and discuss amelioration practices and benefits for crop production. This book will be of interest to readers involved with agriculture and soil sciences in laboratory, applied or classroom settings.

Download or read book Best Management Practices for Saline and Sodic Turfgrass Soils written by Robert N. Carrow and published by CRC Press. This book was released on 2011-09-12 with total page 498 pages. Available in PDF, EPUB and Kindle. Book excerpt: The complex issues involved in the management of saline and sodic turfgrass soils are enough to perplex even the most experienced site manager — there is no "silver bullet" amendment, treatment, or grass for salinity management. Best Management Practices for Saline and Sodic Turfgrass Soils: Assessment and Reclamation presents comprehensive scientific principles and detailed, practical management and assessment recommendations for turfgrass and landscape sites. The authors use the Best Management Practices (BMPs) concept, considered the gold-standard management approach for any individual environmental issue, since it is a whole ecosystem (holistic), science-based salinity management approach that allows all possible management options to be considered and implemented on a site-specific basis. They identify BMP strategies, including irrigation system design; irrigation scheduling and salinity leaching; chemical, physical, and biological amendments; cultivation; topdressing; soil modification; sand-capping; surface and subsurface drainage options; nutritional practices; additional cultural practices; and ongoing monitoring. The book presents emerging challenges, technology, and concepts that address integration of salinity management into comprehensive site environmental or sustainable management systems, use of halophytic turfgrasses for non-traditional purposes, integration of geospatial and geostatistical concepts and technology, and integration of new sensor technology into daily management paradigms. Outlining a holistic BMP approach, the book incorporates scientific principles and practical management recommendations and details specific salinity challenges and the logic behind each BMP strategy for salinity management, with an emphasis on actual field problems. The book is formatted for flexible use, with stand-alone chapters that include outlines for quick review of a topic for those requiring only a basic understanding as well as in-depth discussions of the science and practical aspects for those seeking a more rigorous treatment. It supplies a single source for all the information required to identify and manage diverse types of salinity stresses.

Download or read book Research Developments in Saline Agriculture written by Jagdish Chander Dagar and published by Springer. This book was released on 2019-06-21 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil and water salinity is a major challenge for the agricultural community and policy makers in terms of meeting the burgeoning population’s demand for food and other agricultural commodities. In coastal regions, climate change and sea level rise will aggravate the problem with more and more areas becoming saline due to intrusion of sea water. As such there is a pressing need for modern tools and innovative techniques for the identification of salty soils and poor-quality waters, crop production, soil reclamation and lowering the water table in waterlogged areas. Tackling next-generation problems such as contamination of soil and underground water due to fluoride and arsenic, as well as developing multi-stress tolerant crops is also a high priority. Further, techniques for domesticating halophytes, mangrove-based aquacultures, using seaweed cultures as agricultural crops and integrated farming systems need to be perfected. This book addresses all these aspects in detail, highlighting the diverse solutions to tackle the complex problem of salinity and waterlogging and safer management of poor-quality waters. With chapters written by leading experts, it is a valuable resource for researchers planning future investigations, policy makers, farmers and other stakeholders, and for students wanting insights into vital issues of environment.

Download or read book Assessment Methods for Soil Carbon written by John M. Kimble and published by CRC Press. This book was released on 2000-12-28 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil sampling and preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues. In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.
