Soil Biology and Agriculture in the Tropics. Dion, Patrice (Ed.) Springer, 2010, XIII, 350 p., Hardcover ISBN: 978-3-642-05075-6. The relationships between soils, microbes and humans are of crucial relevance in the tropics, where plant stress and microbial activity are exacerbated. This volume of Soil Biology presents the living component of tropical soils, showing how it is shaped by environmental conditions and emphasizing its dramatic impact on human survival and well-being. Following an introduction to the specificities of tropical soils and of their microbial communities, the biological aspects of soil management are examined, dealing with land use change, conservation and slash-and-burn agriculture, the restoration of hot deserts, agroforestry and paddy rice cultivation. As they are of particular relevance for tropical agriculture, symbioses of plants and microbes are thoroughly covered, as are the biodegradation of pesticides and health risks associated with wastewater irrigation. Lastly, traditional soil knowledge is discussed as a key to our sustainable presence in this world.

Nutrient Uptake, Removal and Recycling by Crops. by Dr HLS Tandon.and Dr Y. Muralidharudu. 2010. ISBN: 81-85116-61-X. Pages 167+xvi. Fertiliser Development and Consultation Organisation, India, Email: fdco@airtelmail.in or fdco@vsnl.net Price Price:US$ 60 (inclusive of airmail delivery). This compilation and analysis is probably the first one which is exclusively devoted to nutrient uptake, removal and recycling by crops. All major and micro plant nutrients are covered for over 180 crops. These include cereals, millets, grain legumes, crops yielding oils, sugar, fibre , fruits and nuts, vegetables, fodders and forages, pastures, stimulants, plantation crops, tubers, edible roots, those used  as spices and for  garnishing, medicinal and aromatic plants, industrial crops such as mulberry, cluster bean and rubber and finally, some forest tree species. The impact of soil-climate conditions, crop cultivar, season and soil fertility level/fertiliser application on nutrient uptake in relation to economic yield is discussed in relation to absolute yield, per tonne yield production basis and the N:P:K ratios in which these are absorbed with and without fertiliser application Where information is available, partitioning of the absorbed nutrients into various plant parts (both removed from the field and recycled) and their fate is dealt with. Two conclusions drawn are that (i) nutrient uptake estimated at harvest is not necessarily the maximum nutrient uptake by the crop and (ii) nutrient uptake cannot be equated with nutrient removal in most cases.

Soil and Water Conservation Advances in the United States. Ted M. Zobeck and William F. Schillinger, editors. ISBN 978-0-89118-852-0. Harcover, 320 pp. Have agricultural management efforts begun in the desperation of the Dust Bowl brought us to where we need to be tomorrow? Questions about the environmental footprint of farming make this book required reading. Approximately 62% of the total U.S. land area is used for agriculture, and this land also provides critical ecosystem functions. Authors from each region of the continental United States describe the progress of soil and water conservation to date and visualize how agricultural production practices must change in future years to address the newest challenges.
