Available in PDF, EPUB and Kindle. Book excerpt: The cropping system is one of the important components of sustainable agriculture, since it provides more efficient nutrient cycling. As such, balanced fertilization must be based on the concept of sustainable crop production. Feeding the rapidly growing world population using environmentally sustainable production systems is a major challenge, especially in developing countries. A number of studies have highlighted the fact that degradation of the world's cultivated soils is largely responsible for low and plateauing yields. Soil is lost rapidly but only formed over millennia, and this represents the greatest global threat to nutrient dynamics in agriculture. This means that nutrient management is essential to provide food and nutritional security for current and future generations. Nutrient dynamics and soil sustainability imply the maintenance of the desired ecological balance, the enhancement and preservation of soil functions, and the protection of biodiversity above and below ground. Understanding the role of nutrient management as a tool for soil sustainability and nutritional security requires a holistic approach to a wide range of soil parameters (biological, physical, and chemical) to assess the soil functions and nutrient dynamics of a crop management system within the desired timescale. Further, best nutrient management approaches are important to advance soil sustainability and food and nutritional security without compromising the soil quality and productive potential. Sustainable management practices must allow environmentally and economically sustainable yields and restore soil health and sustainability. This book presents soil management approaches that can provide a wide range of benefits, including improved fertility, with a focus on the importance of nutrient dynamics. Discussing the broad impacts of nutrients cycling on the sustainability of soil and the cropping systems that it supports, it also addresses nutrient application to allow environmentally and economically sustainable agroecosystems that restore soil health. Arguing that balanced fertilization must be based on the concept of INM for a cropping system rather than a crop, it provides a roadmap to nutrient management for sustainability. This richly illustrated book features tables, figures and photographs and includes extensive up-to-date references, making it a valuable resource for policymakers and researchers, as well as undergraduate and graduate students of Soil Science, Agronomy, Ecology and Environmental Sciences.

Book excerpt: This book is the first to explore the distribution, fate, and ecology of phage in the environment and point up the important applications of this information. The text begins with an historical overview, followed by a discussion of the current state of phage taxonomy. Next is covered the distribution patterns and fate of phage in diverse environments, e.g. soil, fresh water, marine water, and water and wastewater treatment plants. Factors that can influence the numbers and activity of phage populations, e.g. host and phage density, association of a phage with solids, presence of organic matter, temperature, pH, ultraviolet and visible light, concentration and types of ions present, and the metabolic activities of bacteria other than the phage host are examined. One chapter is devoted to the occurrence and implications of phage in various industries, e.g. dairy, wine, sausage, and antibiotic industries.

Book excerpt: Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.

Download or read book Not by Bread Alone written by Vilhjamur Stefansson and published by Echo Point+ORM. This book was released on 2020-08-31 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: The arctic explorer’s classic text on the benefits of an all-meat diet chronicles his experiences and clinical studies of Inuit food habits. Arctic explorer and anthropologist Vilhjalmur Stefansson spent years living with indigenous Inuit and Eskimo people. He noted their general healthiness (and good teeth), and an absence of many of the diseases that plagued western cultures, such as scurvy, heart disease, and diabetes. Observing their dietary habits, he determined that their primary food was meat, both lean and fatty, and that their diets were very low in sugary or starchy carbohydrates. Was this meaty diet the key to their good health? Stefansson’s classic Not By Bread Alone chronicles a 1928 scientific experiment, conducted by the Russell Sage Institute of Pathology at Bellevue Hospital in New York, in which Stefansson and his colleague Dr. Karsten Andersen ate a meat-only diet for one year. The two men stayed healthy and fared very well, leading him to claim that we should reexamine our notion of what foods constitute a healthy diet. Later chapters promote the benefits of pemmican, a compact, portable, and high-energy food consisting of a concentrated mix of fat and protein made from dried lean bison meat—sometimes mixed with berries—what you might call the original energy bar.
