Book Description
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.

Book Description
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.

Book Description
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.

Book Description
Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.
