It is now well recognized that nutrient imbalances have a substantial impact on the productivity and sustainability of agroecosystems worldwide. Fertilizer and manure use, atmospheric deposition, international transportation of produce, solute and gas emissions and soil erosion have all contributed to acute deficits and surpluses. This work ...
Soil degradation and nutrient depletion have become serious threats to agricultural productivity in Africa. Soils cannot supply the quantities of nutrients required and yield levels decline rapidly once cropping commences. This book addresses these issues and includes papers from an international symposium held at Cotonou, Benin, October 9-12, ...
During the past 30 years crop yields, particularly of rice, have been greatly increased in many Asian countries by advances in plant breeding and by the application of nitrogenous and phosphatic fertilizers. This has become known as the "Green Revolution", which has been a major factor underpinning the growth of Asian economies, providing a cheap, ...
This is a new edition of the book previously titled Solute Movement in the Soil-Root System, and describes in detail how plant nutrients and other solutes move in the soil in response to plant uptake. It provides a basis for understanding processes in the root zone so that they can be modelled realistically in order to predict the effects of ...
Each of these popular handbooks contains comprehensive information on the nutritional needs of domestic animals and includes extensive tabular data. All are paperbound and measure 8 1/2 x 11.
"Soil Biota, Nutrient Cycling and Farming Systems" is a timely reference volume that explores the relationship between soil biota and environmental and agricultural practices. It addresses topics such as agroecosystems structure and function, cycling of nutrients and soil contamination, use of soil invertebrates as soil bioindicators, application ...
Plant nutrients are found in a relatively thin layer of soil materials which cover all of the continents. These nutrients provide the necessary food, clothing and shelter for human existence. As the population of the world increases, the plant nutrients in desert environments become more and more important for the survival of mankind. This study ...
