There is no textbook covering the content of entire course in agro meteorology offered for undergraduate students of agricultural universities in India. Students have to refer various books monographs and periodicals to collect the information for various courses offered in the field of agrometeorology. The present textbook is written to satisfy the various course requirements. The subject matter is both narrative and critical. Illustration have been added to make the subject matter all the more clear. At the end of each chapter a list of references have been given from which most of the material in the chapter is drawn. These references will also help the post graduate students for further reading. At the end of all chapter a list of terminology of agrometeorology has also been included to help students know about terms of agrometeorology. The authors acknowledge their indebtedness to the authors of various books monographs and periodicals from which they have drawn the matter in this textbook. In cases where a few tables have been reproduced acknowledgement is duly credited beneath each reproduction however in a few cases where it has not been possible to contact and obtain permission for reproduction the authors and publishers offer their sincere apologies. It is felt that this textbook meets a long felt need of students. We welcome suggestions from teachers as well as students to make the book more useful. Suggestions will receive the greatest consideration. 144 pp.

"Fertilizers have played a key role in the modernisation of Indian agriculture and in making the country self sufficient in food grain production. P is reported to be the limiting plant nutrient in soils and is considered to be the key to crop productivity. Most soils contain insoluble inorganic phosphates but they are of no use to crops unless they are solubilized. Much of the soluble phosphates applied to soils as fertilizers is fixed by the soil and rendered less available to plants. The long term application of P fertilizers has resulted in an accumulation of total soil P, most of which is poorly soluble. Phosphate Solubilizing Microorganisms (PSM) are capable of solubilizing tricalcium, aluminium and iron phosphates, as well as rock phosphate making the phosphorus present in the soil available to plants. Soils also contain organic phosphorus, which can be used by crops only if it is mineralized. Microorganisms play active part in the decomposition and mineralisation of organic matter and release of nutrients. Organisms that cause increases in plant available P in the soil system belong to a diversified group including bacteria, actinomycetes and several group of fungi. Huge investments would have to be made in fertilizer factories to meet growing demand of phosphatic fertilizers. The fertilizers so produced 224 pp.

Green manuring is the practice of ploughing or turning into the soil un decomposed green plant tissues for the purpose of improving the soil. It is an age old practice adopted to improve the productivity of soil. Green manuring has received little attention during past few decades mainly because of the fertilizers have become the most commonly used source of supplying nutrients to crop plants. The low cost and ready availability of chemical fertilizers has pushed back the use of green manuring all over the world. However in the face of continuing energy crisis increasing fertilizer prices and increasing concern for environmental degradation green manuring is increasingly appealing as a means to reduce losses of soil organic matter compaction and soil erosion and still maintain economic returns. The importance of nitrogen and manuring in improving soil productivity is an established fact all over the world. The use of green manure crops will aid in intensive production which can not be sustained with cattle dung manure alone. An effort has been made in this book to collate information on various facets of green manuring ease of decomposition the relative utility of legumes and nonlegumes as green manure the effect of green manuring on soil physical and chemical properties in addition to that on nutrient availability and crop responses have been elucidated based on existing information. 464 pp.

Hardcover. Zustand: As New. Contents Preface. About the book. Preamble. 1. Introduction. 2. Materials suitable for composting. 3. Dynamics of composting. 4. Progression of the composting process. 5. Aerobic composting. 6. Composting systems. 7. Traditional methods of composting. 8. Rapid methods. 9. Quality of compost. 10. Maturation of compost. 11. Problem associated with low use of compost. 12. Design criteria and field application of compost. 13. Crop response to composting. 14. Summary and conclusions. Glossary. References. Subject index. Composting is the biological decomposition and stabilization of organic substrates under conditions that allow development of thermophilic temperatures as a result of biologically produced heat to produce a final product that is stable free of pathogens and plant seeds and can be beneficially applied to land. Composting is one of the best method of recycling to improve soil fertility as well as disposal of organic wastes to check environmental pollution and health hazards. Manipulating moisture content pH nutrient concentration and oxygen can bring about increased decomposition rates and change the characteristics of the compost. Techniques have been developed to produce plant nutrient enriched organic bio fertilizer which can form an important input in Integrated Plant Nutrient Supply (IPNS) system and organic farming. Earthworms may also play a significant role in composting of animal dung mixed with leaf litter and grosses in shallow and small sized windrows or heaps. This book provides comprehensive account of composting technology. 456 pp.
