Book Description
This book will address the major subsoil physical and chemical constraints and their implications to crop production; Plant growth is often restricted by adverse physical and chemical properties of subsoils yet these limitations are not revealed by testing surface soils and hence their significance in crop management is often overlooked. The major constraints can be physical or chemical. Physical limitations such as poor/nil subsoil structure, sandy subsoils that do not provide adequate water or gravelly subsoils and, etc. On the other hand, chemical constraints include acidity/alkalinity, high extractable Al or Mn, low nutrient availability, salts, boron toxicity and pyritic subsoils. Some of these constraints are inherent properties of the soil profile while others are induced by crop and soil management practices. This aim of this book is to define the constraints and discuss amelioration practices and benefits for crop production. This book will be of interest to readers involved with agriculture and soil sciences in laboratory, applied or classroom settings.

Book Description
Globally, over two thirds of soils are affected by physical, chemical, or biological soil constraints. These constraints cause significant yield loss, and, as such, identifying appropriate management strategies is crucial to ensure future world food production. In order to help agricultural researchers and practitioners better understand soil constraint management, this book comprehensively outlines the occurrence of the major soil constraints and the most appropriate strategies to manage these for sustainable food production. Importantly, it brings together experts from major agricultural regions globally to highlight approaches with the most success in different environmental and socioeconomic regions worldwide.

Book Description
Identifying, interpreting, and managing soil constraints are major challenges, especially when multiple constraints occur in the same soil at various depth zones. Although amelioration tools and strategies are available to manage some of these constraints, field adoption of these technologies is a major challenge to the farming community. Soil Constraints and Productivity helps in identifying and understanding soil constraints, focusing on management practices to alleviate problems associated with these restrictions, and their impacts on crop productivity. Soil Constraints and Productivity aims to: Describe various strategies suitable for mitigating soil constraints Provide data on cost-benefit analysis of managing soil constraints Provide case studies of managing soil constraints to increase productivity Soil is essential for the doubling of major grain production proposed to be necessary to avoid major food security collapses in the future. This book will be a key resource for soil and environmental scientists, farmers, students majoring in agricultural and environmental sciences, and crop consultants.

Book Description
This publication provides an overview of the world's land resources characteristics, their status and limitations at a global, regional and national level. The statistics given include data on soil, climate and terrain characteristics and constraints, human-induced land degradation status and desertification risk. A comparative analysis of national land resource potential is included. A link is made between the land resource limitations and the population affected.

Book Description
The world has made remarkable progress in maintaining adequate food supplies during the past quarter century by introducing yield-increasing technologies such as better genetics, crop protection products, and more efficient use of fertilizers and irrigations. Far more people depend on irrigation in the modern world than during the times of ancient Sumeria. The spread of irrigation has been the key factor in increasing global crop yields. But future scarcity present the single biggest threat to future food production. The shift of water from agriculture to the growing cities and industry almost certainly will impact global food production. This means that dryland agriculture will be increasingly important in meeting food requirement for the growing population. Advaces in plant genetics and agronomic conservation technologies, when considered in concert, continue to provide the greatest opportunities to achieve sustainability and profitability in dryland agriculture and will continue to be the focus of the ARS research program. The ARS is please to join the crop Science Society of America and international center for Agriculture Research in Dry Areas (ICARDA) in sponsoring a symposium “Challenges and strategies for Dryland Agriculture” at the Trisocieties Annual Meeting in November 2002 at Indianapolis, IN. This special publication contains an impressive series of paper by international group of experts on dryland agricultural production, conservation, and policy. The principles, philosophies, and technologies presented in this publication have the potential to contribute to improve food security and livelihoods for the people in dryland regions of the world.

Book Description
Under ongoing climate change, natural and cultivated habitats of major food crops are being continuously disturbed. Such condition accelerates to impose stress effects like abiotic and biotic stressors. Drought, salinity, flood, cold, heat, heavy metals, metalloids, oxidants, irradiation etc. are important abiotic stresses; and diseases and infections caused by plant pathogens viz. fungal agents, bacteria and viruses are major biotic stresses. As a result, these harsh environments affect crop productivity and its biology in multiple complex paradigms. As stresses become the limiting factors for agricultural productivity and exert detrimental role on growth and yield of the crops, scientists and researchers are challenged to maintain global food security for a rising world population. This two-volume work highlights the fast-moving agricultural research on crop improvement through the stress mitigation strategies, with specific focuses on crop biology and their response to climatic instabilities. Together with "Climate Resilient Agriculture, Vol 2: Agro-Biotechnological Advancement for Crop Production", it covers a wide range of topics under environmental challenges, agronomy and agriculture processes, and biotechnological approaches, uniquely suitable for scientists, researchers and students working in the fields of agriculture, plant science, environmental biology and biotechnology.

Book Description
"With ever-increasing pressures on world agriculture in both economic and environmental terms, application of the concept of precision agriculture is one way of enabling farmers and producers to cope. ‘Doing arable agriculture and horticulture more precisely’ means that the use of inputs is optimised, crop yield and quality are maximised and leakage of agro-chemicals and fertilisers to the environment is minimised. This publication contains papers presented at the 6th European Conference on Precision Agriculture. The papers reflect the wide range of disciplines encompassed by precision agriculture, including: soil physics, crop physiology, agronomy, IT, agricultural technology, sensor technology, remote sensing, geostatistics and environmental science. The wide range of research topics reported will be a valuable resource for researchers, advisors, teachers and professionals in agriculture long after the conference has finished. Peer-reviewed papers from the 3rd European Conference on Precision Livestock Farming are presented in a companion proceedings, Precision livestock farming ’07."
