Download or read book Nutrient Control Actions for Improving Water Quality in the Mississippi River Basin and Northern Gulf of Mexico written by National Research Council and published by National Academies Press. This book was released on 2009-08-13 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large area of coastal waters in the northern Gulf of Mexico experiences seasonal conditions of low levels of dissolved oxygen, a condition known as hypoxia. Excess discharge of nutrients into the Gulf of Mexico from the Mississippi and Atchafalaya rivers causes nutrient overenrichment in the gulf's coastal waters and stimulates the growth of large algae blooms. When these algae die, the process of decomposition depletes dissolved oxygen from the water column and creates hypoxic conditions. In considering how to implement provisions of the Clean Water Act to strengthen nutrient reduction objectives across the Mississippi River basin, the U.S. Environmental Protection Agency (EPA) requested advice from the National Research Council. This book represents the results of the committee's investigations and deliberations, and recommends that the EPA and U.S. Department of Agriculture should jointly establish a Nutrient Control Implementation Initiative to learn more about the effectiveness of actions meant to improve water quality throughout the Mississippi River basin and into the northern Gulf of Mexico. Other recommendations include how to move forward on the larger process of allocating nutrient loading caps-which entails delegating responsibilities for reducing nutrient pollutants such as nitrogen and phosphorus-across the basin.

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.

This book was released on 2012-01-01 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated nutrient management involving different organic sources like FYM, vermi-compost, crop residue, green manure, Bio-fertilizer and in-situ role of legumes along with balanced nutrient use (major and micro-nutrients) deserves due attention. In fact, based on series of experiments and studies conducted all over the country with reference to nutrient management for various crop as applicable to varying soil environment representing different agro-climatic zones have been generated at national level but the system based information’s on integrated nutrient management is still lacking and yet to be documented. In this publication 1, 3 and 4 deals with general issues and management options for integrated nutrient management with special reference to irrigated eco-system, while 2 focused on crop residue management. The 5 and 10 are enlightens the soil-test based nutrient management for sustainable soil health, while s 6 and 7 are related to nutrient economy through integrated farming system and inclusion of legumes under cereal based cropping systems. The 8 is focused on integrated nutrient management in rice-wheat cropping system, while 9 on oilseed based, 11 on soybean based, 13 on vegetable and 23 on seed spices based cropping systems. The issues related to SSNM, protected agriculture, soil chemical, biological and microbial diversity are discussed in 12, 14 and 18, respectively. The aspects related to system based nutrient budgeting, soil carbon management and sequestration, balanced crop nutrition in relation to crop diseases, economics and nutrient modeling have been duly discussed in s from 19 to 25.

This book was released on 2018-11-06 with total page 330 pages. Available in PDF, EPUB and Kindle. Book excerpt: This user-friendly, practical guide was written for large and small greenhouse producers of containerized crops throughout the United States and all climates of North America. Inside you’ll find a thorough overview of plant nutrition and water quality. Originally associated with floriculture crops and “out-of-season” vegetable production, greenhouse production has experienced a recent sea change: new marketing trends, organic production, improved and more efficient production technologies, and the introduction of new laws and regulations related to environmental sustainability and food safety. To be successful, professional growers need to be equipped with a comprehensive understanding of greenhouse management today. Written by industry-based professionals and academics, its seventeen chapters demonstrate how water, root media, and fertilizer are integrated to optimize plant health, production efficiency, and the sustainability of resources and the environment.
Download or read book Nutrient Management in Agricultural Watersheds written by E.J. Dunne and published by BRILL. This book was released on 2023-08-28 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient enrichment of water resources by inputs of nitrogen and phosphorus, which can lead to eutrophication is still a water quality problem in agriculturally dominated watersheds around the world. Internationally, wetlands both constructed and natural are increasingly being used to help reduce both point and non-point source nutrient and contaminant loss from agricultural practices. This publication contains papers presented at the international symposium on "Nutrient Management in Agricultural Watersheds: A Wetlands Solution," which was held during May, 2004 in Wexford, Ireland. The symposium was the result of an international collaboration between the Teagasc Research Centre, Johnstown Castle, Ireland, National Parks and Wildlife, Department of Environment, Heritage and Local Government, Ireland and the Soil and Water Science Department at the University of Florida, Gainesville, USA. These proceedings cover aspects of water quality within agricultural watersheds; management practices to mitigate contaminant and nutrient loss from agriculture; wetland biogeochemistry; wetland functions and values within agricultural dominated landscapes; case studies of wetlands used to retain nutrient and contaminant loss from agriculture; and finally some management and policy issues concerning wetlands are presented. This book provides a good interdisciplinary synthesis of international experiences both in Europe and the USA on the use of wetlands within agricultural watersheds.
Download or read book Integrated Nutrient Management Practices for Soil Health Need of Hour written by Sunil Kumar and published by Blue Rose Publishers. This book was released on 2023-01-05 with total page 87 pages. Available in PDF, EPUB and Kindle. Book excerpt: Intensive agriculture system, while increasing food grain production, has caused second-generation problems concerning nutrient imbalance. Some, other problems like greater mining of nutrients from the soil, soil fertility depletion, emerging multiple nutrient deficiencies, secondary and micronutrients, fall of the water table and deteriorate water quality, decline organic carbon and an overall deterioration in soil health. In INM, crop yields can be increased while minimizing nutrient losses to the environment by managing nutrient supply in the root zone within a reasonable range, Soil physico-chemical and biological properties are closely related with SOC and OM, thus, any soil management practices that enhance soil organic matter, microbial biomass and soil health, for this, combined use of organic and inorganic nutrient sources might be the right proposition for these soils, primarily for the improvement of soil health.. The research main motive was to find out the best-integrated practice which can be used to find out the best INM practice that can help to overcome this problem.

This book was released on 2009-05-07 with total page 277 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agriculture is the main occupation in India and about 75% of its population depends directly or indirectly on agriculture for their livelihood. It is the dominant sector that contributes 18% of the gross domestic product. Thus, agriculture is the foundation of the Indian economy. The maximum share of Indian exports is also from the agriculture sector. As the population of the country is increasing trem- dously, approximately at the rate of 19 million every year over the existing popu- tion of more than 1 billion (approximately 1. 18 billion), the food grain production must necessarily be increased. This can be done by increasing crop production to match the population growth rate of 2. 2% per annum, which is expected to stabilize at 1. 53 billion around 2050. There is no doubt that the Green Revolution in India during the late 1960s brought self-sufficiency in food grain production, mainly through the increase in rice and wheat crop yields – the two main crops of the country which play an important role from food security point of view. However, the excessive use of fertilizers and pesticides, and the neglect of organic manures for these crops, has resulted in the deterioration of physical, chemical and biological health of the ri- and wheat-growing soils. Owing to the deterioration of the health of these soils, the productivity of the rice–wheat cropping system has now either got reduced or in some places has become constant for the last decade.

This book was released on 1996-05-22 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrient management is an important aspect of feeding livestock and poultry. Today, there is more attention directed toward this issue in animal production than ever before. The heightened awareness of the environmental impacts associated with animal production has caused animal nutritionists to refocus their thoughts, practices, and expectations regarding how nutrients are supplied to animals. In addition, the increase in the size and intensity of modern production units demands new technologies for enhancing nutrient utilization and for reducing the amount of nutrients excreted. Covering these issues and more, Nutrient Management of Food Animals to Enhance and Protect the Environment is a reference tool for agricultural industry leaders, private practitioners, government agencies, and researchers.
