Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is indispensable to all life on Earth. However, humans now dominate the nitrogen cycle, and nitrogen emissions from human activity have real costs: water and air pollution, climate change, and detrimental effects on human health, biodiversity, and natural habitats. Too little nitrogen limits ecosystem processes, while too much nitrogen transforms ecosystems profoundly. The California Nitrogen Assessment is the first comprehensive account of nitrogen flows, practices, and policies for California, encompassing all nitrogen flows—not just those associated with agriculture—and their impacts on ecosystem services and human wellbeing. How California handles nitrogen issues will be of interest nationally and internationally, and the goal of the assessment is to link science with action and to produce information that affects both future policy and solutions for addressing nitrogen pollution. This book also provides a model for application of integrated ecosystem assessment methods at regional and state (subnational) levels.

Download or read book Efficient Nutrient Management in California Vegetable Production written by Timothy K. Hartz and published by UCANR Publications. This book was released on 2020-07-14 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: With growers now facing increasingly stringent regulations designed to minimize nutrient losses to the environment, this guide outlines a fresh take on fertilization best practices for the industry. Nutrient management is critical to successful vegetable production. Given the high value and exacting market standards for size, appearance, and postharvest quality for vegetable crops, fertilizer management practices have focused on optimizing production across a wide range of field conditions. While effective in producing good crops, these practices are not necessarily reflective of input costs or environmental protection. Drawing on 25 years of industry experience, the author outlines the principles of nutrient management that are broadly applicable across crops and production regions. Growers, PCAs, and fertilizer industry professionals will find a practical understanding of crop nutrient requirements, soil nutrient availability, the value and limitations of soil and plant nutrient monitoring, and environmental protection in these pages.
Download or read book Possibility of Reducing Nitrogen in Drainage Water by on Farm Practices written by John W. Williford and published by . This book was released on 1972 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report is one of a series which presents the findings of intensive interagency investigations of practical means to control the nitrate concentration in subsurface agricultural waste water prior to its discharge into other water on such areas as the San Joaquin Valley. As a result of the application of large quantities of water to relatively slowly permeable stratified soils, the west side of the San Joaquin Valley now has large areas with groundwater at rootzone depths. Wherever subsurface drains have been installed to control this groundwater, the drainage effluent has had high nitrate concentrations. Large quantities of inorganic nitrogen fertilizers are applied annually and the assumption prevails that fertilizer is the major source of nitrates in the drainage water. The study was designed to evaluate this assumption and to derive, if possible, practical answers regarding the role of on-farm practices in controlling nitrate out-put from the agricultural lands. Examined are the nitrogen budget and methods for reducing the quantity of nitrates in the drainage effluent by modifications in type or use of fertilizers, practicespractives, or drainage techniques.
