Great attention has been paid to reduce the use of conventional chemical fertilizers harming living beings through food chain supplements from the soil environment. Therefore, it is necessary to develop alternative sustainable fertilizers to enhance soil sustainability and agriculture productivity. Biofertilizers are the substance that contains microorganisms (bacteria, algae, and fungi) living or latent cells that can enrich the soil quality with nitrogen, phosphorous, potassium, organic matter, etc. They are a cost-effective, biodegradable, and renewable source of plant nutrients/supplements to improve the soil-health properties. Biofertilizers emerge as an attractive alternative to chemical fertilizers, and as a promising cost-effective technology for eco-friendly agriculture and a sustainable environment that holds microorganisms which enhance the soil nutrients' solubility leading a raise in its fertility, stimulates crop growth and healthy food safety. This book provides in-depth knowledge about history and fundamentals to advances biofertilizers, including latest reviews, challenges, and future perspectives. It covers fabrication approaches, and various types of biofertilizers and their applications in agriculture, environment, forestry and industrial sectors. Also, organic farming, quality control, quality assurance, food safety and case-studies of biofertilizers are briefly discussed. Biofertilizers' physical properties, affecting factors, impact, and industry profiles in the market are well addressed. This book is an essential guide for farmers, agrochemists, environmental engineers, scientists, students, and faculty who would like to understand the science behind the sustainable fertilizers, soil chemistry and agroecology.

The dependence of present farming on artificial input of “chemical fertilizers” has caused numerous ecological tribulations associated with global warming and soil contamination. Moreover, there is an essential requirement for realistic agricultural practices on a comprehensive level. Accordingly, biofertilizers including microbes have been recommended as feasible environmentally sound solutions for agricultural practices which not only are natural, and cost-effective but also preserve soil environs and important biota of agricultural land. In addition, it enhances the nutrient quantity of soils organically. Microbial biofertilizers promote plant growth by escalating proficient absorption of nutrients for the plants and by providing an excellent disease-fighting mechanism.Agriculture, the backbone of human sustenance, has been put under tremendous pressure by the ever-increasing human population. Although various modern agro-techniques boosted agricultural production, the excessive use of synthetic fertilizers, pesticides and herbicides have proven extremely detrimental to agriculture as well as to the environment in which it is carried out. Besides this some faulty agricultural practices like monoculture and defective irrigation, further complicate the scenario by eliminating biodiversity, increasing the efflux of nutrients into the water bodies, the formation of algal blooms, eutrophication, damaging the water quality and lowering fish stocks. Biofertilizers are the organic compounds applied to crops for their sustainable growth and the sustainability of the environment as the microbiota associated with biofertilizers interact with the soil, roots and seeds to enhance soil fertility. Application of biofertilizers results in the increased mineral and water uptake, root development, vegetative growth and nitrogen fixation besides liberating growth-promoting substances and minerals that help the maintenance of soil fertility. They further act as antagonists and play a pivotal role in neutralising soil-borne plant pathogens and thus, help in the bio-control of diseases. Application of biofertilizers instead of synthetic fertilizers could be a promising technique to raise agricultural productivity without degrading environmental quality. The present book focuses on the latest research approaches and updates from the microbiota and their applications in the agriculture industry. We believe this book addresses various challenges and shed lights on the possible future of the sustainable agricultural system.

It has been recognized that these environment-friendly bioprotectors, growth boosters, and remediators are essential for soil/plant health. The Handbook of Microbial Biofertilizers is designed to fit the expanding information needs of current and future biotechnologists, microbiologists, botanists, agronomists, environmentalists, and others whose work involves sustained agriculture.

Chemical fertilizers are widely used with the purpose to enhance output in various product varieties in agriculture. As, chemical fertilizers are the big¬gest reason of posing pollution to the water bodies, ground water, and also bioaccumulates in crops hence badly destroying ecological cycles. Therefore, modern scientists are focusing to switch completely from chemical farming to organic farming in order to encourage sustainable agriculture. In organic farm¬ing crops are not polluted as they rose through use of manures, biofertilizers and biopesticides which not only provides optimum nutrients to plants but also keep pests and pathogens in control. Biofertilizers are actually "microorgan¬isms which bring roughly nutrient enrichment of soil through enhancing the availability of nutrients to plant crops". These micro-organisms who exhibit the ability to act as bio-fertilizers are the bacteria, cyanobacteria and mycor¬rhizal fungi. Biofertilizers provides considerable potent benefits to agriculture as well as public health programmes. Both developing and developed countries have a vast potential for biofertilizers. However, their adoption by farmers es¬pecially in developing countries needs education for maximizing benefits. The stress on organic farming as well as on residue free materials would certainly merit enhanced adoption of biofungicides by the farmers. The use of fungicides reduces crop productivity loss because the chemically synthesized pesticides are no doubt quick in their effect but on the other hand they cause so many environmental and health just as revival of new pests, fungal resistance, loss of soil fertility and persistence of toxic substances when they are consumed by animals and humans. All these problems call for an eco-friendly and sustainable approach in order to decrease the usage and dependence of chemically synthe¬sized fertilizers and pesticides. Similarly, there are so many natural fungicides that can be best alternatives to control fungi and enhancing plant life. Thus, the purpose of this book is to provide that knowledge about recent advancements in the emerging fields of Biofertilizers and Biofungicides as both of them are considered to be ecofriendly as well as sustainable substitutes to chemical fertilizers and fungicides respectively.Chapter 1- 10 discusses all aspects of biofertilizers with special focus on recent advances in this technology while Chapter 11- 14 are about Biofungicides, their applications and recent advances in this field of organic farming.

This volume addresses various issues related to micronutrient deficiency, especially zinc, and discusses the possible approaches for combating mineral deficiency among humans and plants. The book mainly focuses on the zinc biofortification of vegetable and cereal crops and highlights the consequences of zinc deficiency and the health risks associated with zinc deficiency, especially in children and expecting mothers. The authors discuss different types of food that are rich in zinc and other minerals, how diets can be designed to meet the daily zinc requirements, and the impact of zinc deficiency on plant health and quality of agricultural products and the role of micronutrients in abiotic stress tolerance. The book also covers sustainable approaches to zinc biofortification in crops, such as the microbial solubilization of zinc in soil to improve zinc uptake by plants, and the formulation of these microbes into biofertilizers. The book will be of interest to dieticians, agricultural scientists, students and microbiologists.
