DOWNLOAD EBOOKGreat 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.

DOWNLOAD EBOOKImproving Water and Nutrient Use Efficiency in Food Production Systems provides professionals, students, and policy makers with an in-depth view of various aspects of water and nutrient us in crop production. The book covers topics related to global economic, political, and social issues related to food production and distribution, describes various strategies and mechanisms that increase water and nutrient use efficiency, and review te curren situation and potential improvements in major food-producing systems on each continent. The book also deals with problems experienced by developed countries separtaely from problems facing developing countries. Improving Water and Nutrient Use Efficiency emphasizes judicious water and nutrient management which is aimed at maximising water and nutrient utilisation in the agricultural landscape, and minimising undesirable nutrient losses to the environment.

DOWNLOAD EBOOKThe Pharoahs were masters of the Nile: they had a detailed understanding of the ways of the river. Modern Egyptians see themselves as heirs to this tradition, and as owners of the Nile waters. In the 1960's, Egypt decided to protect its increasingly-populated Nile valley from the ravages of annual flooding by building a dam. A relatively small dam in the valley of Nubia, in the region of Tushka, would have enabled the excess floodwaters to safely be diverted towards the fossil valley of the pre-Nile. However, it was decided to select a site near Aswan, making it necessary to inundate more than 250km of river valley. Over the years, this strategy has been revealed to have been faulty, and numerous irrigation schemes in upriver countries have progressively reduced the amount of water descending into Egypt. The dire warning of the 14th century oracle appears to be prophetic: "the water of the river in my country will be stopped from reaching yours, which I shall cause to die of thirst..."
