This book was released on 2006 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land And Soil Are Non-Renewable Natural Resources. The Nature Has Taken Thousands Of Years To Create An Inch Of Fertile Soil. Mismanagement Of This Precious Resource Is A Sin Against Nature And Will Play Havoc With The Fortunes Of The Country. Many Parts Of The Country Have Already Come To The Brink Of Devastation Through Injudicious Usages, Over Exploitation Of Natural Resources Resulting In Unsustainable Productivity Of Crops.Modern Concept Of Cropping System Is Based On The Principle Of Effective Utilization Of Soil Water, Nutrients And Light For Sustainable Crop Productivity. This Book Gives The Basic Principles And Broadly Accepted Definitions Terms Frequently Used In The Literature. A Short-Review Of The Cropping Systems Work Done In The Tropics, Particularly In India Is Presented.In This Revised Edition, Contents Of All The Chapters Have Been Revised To Give Orientation Towards Management Of Sustainable Crop Production Systems. A New Chapter On Farming System Is Also Added In Tune With The Latest Trends. Information Available On Perennial Crop-Based Cropping Systems, For Example High Density Multi Species Cropping Systems Involving Coconut And Arecanut Is Updated. The Various Management Aspects Of Sustainable Cropping Systems Are Discussed And The Research Methodology That Could Be Adopted Is Elucidated. Possible Future Lines Of Work Are Given In The Final Chapter.This Book Will Prove To Be Of Immense Value Not Only To The Research Workers But Also To The Teachers And Students And Above All Farmers And Individuals Who Are Desirous Of Improving Sustainable Crop Production Systems.

Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book excerpt: Annotation. Successful agroforestry requires an understanding of the complex relationship between trees, crops and soils. This book provides a review of both economic and biophysical aspects of soil use and research in agroforestry, with an emphasis on nutrient-poor forest and savanna soils. Key topics covered include the economics of soil fertility management, cycling of water, nutrients and organic matter, soil structure, and soil biological processes. The book combines synthetic overviews of research results and a review of methods used in research.From the foreword: 2The book is written within a particular context - soil fertility development under agroforestry. At first this may seem very specific and thus limited in appeal and application. But over the last decade or so agroforestry research has been one of the most influential in developing new insights into soil biology and fertility and thus provides a very suitable framework for review of progress. Furthermore the influence of trees on soil is profound and of significance beyond agroforestry systems, so the book is likely to be of interest in the wider spheres of agriculture, forestry and ecological sciences.3 Mike Swift, TSBF, Nairobi, Kenya.

Available in PDF, EPUB and Kindle. Book excerpt: Below-grownd interactions are often seen as the 'dark side' of agroecosystems, especially when more than one crop is grown on the same piece of land at he same time. this book aims to review the amount of light he past decade of research has shed on this topic. It also aims to review ohw far we have come in unravelling the positive and negative aspects of these interactions and how, in dialogue with farmers, we can use the generic principles that are now emerging to look for sita-specifics solutions.
