Mulching in Agroecosystems


Book Description

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.




Soil Water and Agronomic Productivity


Book Description

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.

Role of Mulching in Pest Management and Agricultural Sustainability


Book Description

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.




Agroecosystems


Book Description

Comprised of three sections, this covers the nutrient dynamics and productivity of global agroecosystems. It focuses on the major aspects that make up agroecosystems, such as soils, climate, crops, nutrient dynamics, and productivity. It introduces agroeocsystems and describes global soil types that support vast crop belts, then deals with the principles that drive crop growth, nutrient dynamics and ecosystematic functions within any agroecosystem. It also details the influence of agronomic practices and factors such as soil microbes, organic matter, crop genetic nature, irrigation, weeds, and cropping systems that affect productivity of agroecosystems.

Assessment, Restoration and Reclamation of Mining Influenced Soils


Book Description

Assessment, Restoration and Reclamation of Mining Influenced Soils covers processes operating in the environment as a result of mining activity, including the whole spectra of negative effects of anthropopressure and the environment, from changes in soil chemistry, changes in soil physical properties, geomechanical disturbances, and mine water discharges. Mining activity and its waste are an environmental concern. Knowledge of the fate of potentially harmful elements and their effect on plants and the food chain, and ultimately on human health, is still being understood. Therefore, there is a need for better knowledge on the origin, distribution, and management of mine waste on a global level. This book provides information on hazard assessment and remediation of the disturbed environment, including stabilization of contaminated soils and phytoremediation, and will help scientists and public authorities formulate answers to the daily challenges related to the restoration of contaminated land. - Provides a thorough overview of the processes operating on mining-devastated areas, as well as origin, distribution, and deactivation of harmful elements - Includes outcomes and recommendations of the Global Mining Initiative that are widely regarded as the code of conduct in the minerals industry - Contains global case studies that elucidate various aspects of assessment and restoration of mine-contaminated land




Soil Fertility Management for Sustainable Development


Book Description

Soil fertility is the backbone of agricultural systems and plays a key role in determining food quantity and quality. In recent decades, soil fertility has decreased due to indiscriminate use of agrochemicals, and nations around the globe are now facing the challenge of increasing food production while sustainably maintaining soil fertility. Written by leading international scientists in the field, this book explores soil fertility management strategies, including agronomic, microbiological and soil-science based strategies. Highlighting the practices that can be incorporated into organic farming and discussing recent advances, it is a valuable resource for researchers wanting to broaden their vision and the scope of their investigations.

Soil Degradable Bioplastics for a Sustainable Modern Agriculture


Book Description

This book shows how the use of biodegradable plastics in agriculture can have a profound positive impact on plasticulture. Starting with an organic chemistry approach to biodegradable and compostable plastics, both natural and synthetic, it then analyzes the technological and agronomic aspects of existing bioplastics for protected cultivation (mulching, direct cover, low tunnels). It describes the new sprayable biodegradable mulching method, which is based on the use of waterborne polysaccharides and cellulosic fibers. A further chapter describes the research and technology of biodegradable plastics for different agricultural practices. It also includes chapters on life cycle assessment (LCA) of biodegradable plastics for agriculture, and existing and developing standards in the field. It is a valuable resource for agronomists, chemical and materials engineers, polymer technologists and scientists, as well as for a more general readership interested in the application of green chemistry principles to the vast world of crop production.
