Edward H. Faulkner startled the agricultural world - all of it, on six continents - when he published Plowman's Folly in 1943. As almost everyone knows, he launched a vigorous attack on the plow and dseveloped in a masterful way the advantages of surface incorporation of organic material. The Readers Digest summed up American interest at the time in the statement, ""Probably no book on an agricultural subject has ever prompted so much discussion in this country."" A Second Look is a sequel to Plowman's Folly. In it Mr. Faulkner answers his critics and re-examines the theories expressed earlier, in the light of extensive investigations he subsequently made in visiting experiment stations, soil scientists, and farmers in many parts of the country. Finally, in simple, straightforward language, he gives the lie to ""soil impoverishment."" Highly condensed, here is his thought: The soil which the gardener or farmer works is made up of tiny crystalline fragments. The action of soil acids, principally those released through the decay of organic matter, unlocks the minerals required for healthy plant growth. If this is true, then the indiscriminate and continuous use of commercial fertilizer is a mistake. In fact, says Mr. Faulkner, the ""bank account"" theory of soil is bankrupt. It holds that whatever we take from the soil in the growing of crops must be put back - usually in the form of prepared fertilizers. What the soil needs, on the contrary, is the gentle chemistry described above. If a man cannot learn this, he will pay and pay, ultimately to his ruin. If Plowman's Folly dealt a body blow to deep plowing, then A Second Look sets in revolutionary perspective the whole problem of soil impoverishment. Whether you cultivate a backyard garden or a thousand acres of wheat, this is a book you can hardly afford to miss.

Tea is big business. After water, tea is believed to be the most widely consumed beverage in the world. And yet, as productivity increases, the real price of tea declines while labour costs continue to rise. Tea remains a labour intensive industry. With a distinguished career spanning over 50 years and rich experience in diverse crops, Mike Carr is eminently qualified to indulge in an intelligent discourse on tea agronomy. In addition to a comprehensive review of the principal tea growing regions worldwide in terms of structure, productivity and principal constraints, he has attempted to question and seeks to find the associated experimental evidence needed to support current and future crop management practices. The book will assist all those involved in the tea industry to become creative thinkers and to question accepted practices. International in content, it will appeal to practitioners and students from tea growing countries worldwide.

Plant development and productivity are negatively regulated by various environmental stresses. Abiotic stress factors such as heat, cold, drought, and salinity represent key elements limiting agricultural productivity worldwide. Thus, developing crop plants with the ability to tolerate abiotic stresses is a critical need which demands modern novel strategies for the thorough understanding of plant response to abiotic stresses. Crop Improvement under Adverse Conditions will serve as a cutting-edge resource for researchers and students alike who are studying plant abiotic stress tolerance and crop improvement. The book presents the latest trends and developments in the field, including the impact of extreme events on salt tolerant forest species of Andaman & Nicobar Islands, the overlapping horizons of salicylic acid in different stresses, and fast and reliable approaches to crop improvement through In Vitro haploid production. Written by renowned experts and featuring useful illustrations and photographs, Crop Improvement under Adverse Conditions is a concise and practical update on plant abiotic stress tolerance and crop improvement.

This book provides selected authorship on anthropogenic impacts caused by arsenic, lead, chromium and other pollutants and contaminants emanating from identified activities (e.g. tanning industry, effect of irrigation water and exposure to living tissue). The basis of the study is to improve on the knowledge and spread awareness to the general public. In this book, identified impacts associated with arsenic, chromium, lead, salinity induced processes, effluents and selected synthetic tannins provide a preview of how identified anthropogenic activities can degrade and affect terrestrial, aquatic and human health. In light of this, the individual chapters pursue (to some extent) an experimental and descriptive approach in explaining these aspects. All the contributors of these chapters are specialists in their areas of specialization with very strong research backgrounds. Thus, the book has a formidable basis of communicating the science that is relevant for agronomical activities when evaluating the effluent generation from anthropogenic view, its disposal, potential impacts towards irrigation related to specific geographical areas and the human occupational risks involved overall. It is, therefore, apparent that identifying the denudating aspects of the ecosystems is a paramount step towards building appropriate diagnostic, preventive and curative capabilities in managing the environmental sustainably.
