Biostimulants are synthetic or natural substances that can be used in soil, seeds and plants, and which influence tolerance towards abiotic stress, uptake of nutrients and nutrient efficiency. Seaweed extracts, helpful fungi and bacteria, humic acids, and liquid manure composting are some of the several types of biostimulants. They are increasingly being used in sustainable agricultural practices. These practices strive to strike a balance between the need to produce food and preserving the ecological system. The three primary goals of sustainable agriculture are maintaining environmental health, ensuring economic profitability, and guaranteeing social and economic equity. Biostimulants are compatible with the most progressive farming practices utilized in integrated crop management. They act as soil conditioners and assist the plants in securing nutrients, increasing crop productivity, and repelling pests. This book aims to shed light on the use of biostimulants in sustainable agriculture and crop production. It presents researches and studies performed by experts across the globe. This book will prove immensely beneficial to professionals and students involved in this area of agriculture science.
There is a lot of confusion in alternative agricultural systems being promoted in India and elsewhere.
Sustainable agriculture is an integrated system of plant production practices that aim to satisfy the present food requirements of the society without compromising the needs of the future generations. It also seeks to make efficient use of non-renewable resources to minimize water use, promote soil health, and minimize pollution levels on the farm. Some of the major sustainable agricultural practices (SAPs) and systems that are practiced all over the world include agroforestry, conservation farming, contour farming, covering-mulching, crop-rotation, floating-farming, organic-farming, rainwater-harvesting and vermicomposting. Agroforestry refers to a farming practice wherein forests and shrubs are integrated within animal and crop farming system in order to obtain social, economic and environmental benefits. Conservation farming is an approach to sustainable agriculture which involves minimal disturbance of soil and diversification of plant species. This book includes some of the vital pieces of works being conducted across the world, on various topics related to sustainable agriculture. It unravels the various challenges and opportunities related to sustainable agricultural systems. This book will prove to be immensely beneficial to students and researchers studying sustainable agricultural systems.
Sustainable agriculture refers to a type of farming practice that addresses the needs of present and future generations, while ensuring profitability, environmental health, and social and economic equity. It incorporates a wide range of eco-friendly methods of farming that allow the production of crops or livestock without causing any damage to human or natural systems. Some of the common sustainable agriculture practices include multiple cropping, permaculture, mixed farming, agroforestry, crop rotation, and use of plant biostimulants. In agriculture, biostimulant refers to any substance or a mixture of substances having natural or microbial origin, which helps to improve the condition of crops. The use of biostimulants has shown to stimulate germination, seeding, plant growth, and crop productivity. This book provides comprehensive insights on sustainable agriculture and the application of microorganisms as biostimulants. A number of latest researches have been included to keep the readers updated with the global concepts in this area of study. Students, researchers, experts, and all interested in sustainable agriculture will benefit alike from this book.
Climate-smart agriculture (CSA) is an integrated approach that helps steer actions to transform agri-food systems towards green and climate resilient practices. This approach seeks to manage landscapes such as cropland, livestock, forests and fisheries that address the interlinked challenges of food security and climate change. The negative impacts of climate change can be observed through weather variability, shifting agroecosystem boundaries, invasive crops and pests, and more frequent extreme weather events. CSA endeavors to simultaneously tackle three main objectives. The foremost aim of CSA is to increase the agricultural productivity and incomes in a sustainable manner. Secondly, it seeks to enhance resilience by reducing the vulnerability to drought, pests, diseases, and other climate-related risks. The final objective of CSA is to reduce emissions caused due to greenhouse gas emissions. The topics included in this book on climate-smart agriculture are of utmost significance and bound to provide incredible insights to readers. It will serve as a valuable source of reference for students, policy makers, and researchers studying the impact of climate change on agriculture and agricultural sustainability.
Nitrogen fixation refers to a chemical process in which molecular nitrogen, having a strong triple covalent bond, is converted into ammonia in the air or related nitrogenous compounds found in aquatic systems or soil. Atmospheric nitrogen is molecular dinitrogen that is generally a nonreactive molecule. Biological nitrogen fixation is a microbially mediated process, which utilizes the nitrogenase protein complex for transforming dinitrogen gas into ammonia. Sustainable agriculture refers to a type of farming which aims to fulfill the society's current requirements without compromising the capability of the future generations in meeting their needs. Nitrogen fixation is integral for sustainable food production and agricultural practices. This book provides comprehensive insights on biological nitrogen fixation and sustainable agriculture. Its aim is to present researches that have transformed the study of this subject and aided its advancement. The book is a resource guide for experts as well as students.
