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.
Download or read book Effects of Petroleum Mulch on Soil Water Content and Soil Temperature written by Ahang Kowsar and published by . This book was released on 1968 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Petroleum mulch applied on the soil surface over a row of planted seeds promotes a more rapid and a more uniform germination of seeds, enhances elongation of seedlings and in some cases increases the yield of the crop. The beneficial effects of petroleum mulch have usually been attributed to increased soil temperatures below the mulch. Some reports have pointed out that evaporation of soil water is reduced as a result of the mulch application. An experimental arrangement was designed so that changes in soil temperature and soil water content of mulched and unmulched soil, subjected to the same radiation load could be measured under controlled conditions. Soil at a pre-determined water content was packed into boxes with inside dimensions of 4.0 x 40.0 x 48.0 cm. A ten cm wide band of mulch was applied to one side of the slab leaving 30 cm of bare soil. The soil was subjected to a temperature cycle by turning on infra-red heat lamps at 8:00 A.M., increasing the energy output at hourly intervals with a variable transformer until 2:00 P.M. and then decreasing the energy output until the lights were turned off at 8:00 P.M. Soil temperatures were measured at two-hour intervals with calibrated thermistors inserted into the soil slab. Soil water content changes at selected points were measured at regular intervals with a collimated gamma-beam, movable in a vertical as well as a horizontal direction. The heat flux into the soil was measured with heat flux discs. It was observed that an application of petroleum mulch, changes the temperature and water regime of a soil. The mulch covered soil was about 5°C warmer than the bare soil at the time the soil temperatures attained their maximum value. At all other times the temperature difference between mulched and bare soil was smaller. The bare soil rapidly lost water in the upper four centimeters. The mulch covered soil lost water in the upper cm of soil but gained water at depths below this zone. This gain in water was observed in the zone where seedlings are normally placed, indicating that the beneficial effect of petroleum mulch on germination and seedling growth must be attributed to improved soil water conditions as well as to improved soil temperature conditions.

Available in PDF, EPUB and Kindle. Book excerpt: Crop water use can be increased by management of surface runoff, groundwater, irrigation, and soil water. Technological innovations to enhance availability of water for agricultural crops depend on soil and site-specific conditions. Devoted to the principles and practices of enhancing water use efficiency, Soil Water and Agronomic Productivity addresses current problems associated with water supplies required for agricultural purposes and food production. Written for professionals and students in agricultural fields, the book focuses on innovative technologies for improving soil water availability, enhancing water use efficiency, and using productive irrigation systems. It also presents techniques to conserve water in the root zone as well as remote sensing techniques to assess soil water regime and predict drought on a regional scale. Soil water management is crucial to reducing the vulnerability to agronomic drought. There are numerous examples of aquifers that have been severely depleted by misuse and mismanagement. Soil Water and Agronomic Productivity explains the factors and causes of the mismanagement of soil water and proposes options for sustainable and efficient use of scarce water resources. Meeting the global food demand will require careful worldwide management of soil and water resources, and this can only be done by sharing information and knowledge.

Download or read book Reducing Soil Water Evaporation with Tillage and Straw Mulching written by S. K. Jalota and published by Wiley-Blackwell. This book was released on 1999-05-12 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: As more and more people compete for ever-less water on our shrinking planet, the problem of soil evaporation becomes increasingly urgent. In this book two of the world's most distinguished specialists in the field offer an expert yet highly readable account of both the problem and potential solutions. Drawing on the work of agronomists, soil scientists, and meteorologists, the authors provide a clear overview of the theories and data that explain the process of evaporation from free water and soils that are bare, tilled, or residue-covered. In a discussion of the benefits of tillage in reducing evaporation, they consider different types of soil and the merits of post drying depth-distribution of soil water in treated and untreated soil. Straw mulching, as another means of reducing evaporation, receives the same extended treatment, followed by an appraisal of the effects of different combinations of tillage and mulching on evaporation and water use during fallow and cropped periods. Addressing a pressing issue in a thorough and objective fashion, this book will assist future decision makers about water conservation management in different climates, under various conditions

Download or read book Role of Mulching in Pest Management and Agricultural Sustainability written by Khawar Jabran and published by Springer Nature. This book was released on 2019-08-20 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides the concepts, techniques, and recent developments with regard to use of mulches in agriculture, utility of mulches for non-chemical pest control, and sustainability of crop production systems. Non-conventional means of improving the sustainability of crop production and pest control are required in the wake of environmental concerns over the use of conventional pesticides as well as the intensive use of land resources. Mulches have been used in agriculture for various purposes; however, there has been an increase in their use more recently, and scientists around the world have conducted more research to explore the benefits of mulching in various agricultural systems. Mulches have been found advantageous in non-chemical pest control, soil and water conservation, improving fertility, and improving microbial activities in the soil. While this is a topic of current importance, the information use of mulches in agricultural fields is rarely compiled in one comprehensive location to provide a full account of various aspects of mulches and their utility. This book will be helpful for researchers, growers, and students.
Download or read book Mulching in Agroecosystems written by Kashif Akhtar and published by Springer Nature. This book was released on 2022-11-25 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights into recent developments in the use of mulching in agroecosystems with emphasis on the major pros and cons. Increase in human population, climatic changes and agricultural intensification have put enormous pressure on soil and water resources. As a result, we are confronted with challenges to enhance nutrient and water use efficiencies and conserve soil organic matter without compromising crop yields and food security. Increasing the soil organic matter (SOM) via residue return increased nutrient availability and soil physical and biological properties. Management practices, such as straw mulching or incorporation, have significant effects on soil health. Straw addition also increases functionality related to carbon and N metabolism via increasing the microbes and thus greatly contributes to CO2 and N2O emissions. However, the co-use of organic and inorganic fertilizer reduces the N2O emission without compromising crop yield. Mulching has long been advocated to conserve soil moisture and increase the efficiency of macro- and micro-nutrients by improving soil physical, chemical, and biological properties. These effects of mulch are translated into better crop yields while improving soil health and quality in the long run. Therefore, the use of mulching techniques is on the rise in organic as well as conventional agriculture. The book is of great interest for researchers, academics, agriculture extensionists, soil and plant scientist, fertilizer industry, farmers, agro-industrial workers, farm managers, NGOs, and climate and civil society activists.

Available in PDF, EPUB and Kindle. Book excerpt: Applications of Soil Physics deals with the applications of soil physics and covers topics ranging from infiltration and surface runoff to groundwater drainage, evaporation from bare-surface soils, and uptake of soil moisture by plants. Water balance and energy balance in the field are also discussed, along with tillage and soil structure management. The development and extension of Penman's evaporation formula is also described. This book is comprised of 14 chapters and begins with a systematic description of the field-water cycle and its management, with emphasis on infiltration and runoff; redistribution and drainage; evaporation and transpiration; and irrigation and tillage. Subsequent chapters focus on transpiration from plant canopies; freezing phenomena in soils; scaling and similitude of soil-water phenomena; spatial variability of soil physical properties; and movement of solutes during infiltration into homogeneous soil. Concepts of soil-water availability to plants are considered, together with principles of irrigation management and the advantages and limitations of drip irrigation. This monograph is intended for upper-level undergraduate and graduate students of the environmental, engineering, and agronomic sciences.
