Subject index. Over exploitation and degradation of natural resources is one of the major weaknesses that the present agriculture faces. The soil resource is also under increasing stress as there is a big gap (deficit of about 10 million tonnes NPK nutrients) between annual drain of nutrients from the soil due to crop removals and the nutrient inputs from the external sources. Integrated nutrient management (INM) has been recognized as the economically viable and environmentally benign technology to enhance soil productivity through the balanced use of mineral fertilizers combined with organic sources of plant nutrients. One of the major constraints of INM is the quantity and quality of organic manures available with the farmers. Even though significant quantities of organic manures are available with the farmers, their quality is poor. Lot of research has been done in ICAR Institutes as well as SAUs to enhance the quality of manures by efficient composting techniques, besides developing efficient techniques for nutrient enrichment in different organic manures including municipal solid wastes for efficient recycling of organic wastes for sustainable agriculture. This book contains very useful information on various on-farm and off-farm organic wastes being used for soil fertility management in INM and organic farming, nutrient enriched composts preparation, use of vermicomposting techniques for bio-degradation of organic wastes, conservation agriculture, and the effect of organic wastes on crop and soils quality, soil carbon dynamics. This publication will be quiet useful to researchers, students, extension persons, policy makers and all those engaged in developing efficient nutrient management strategies for sustainable agriculture.

Somani, F.M. Qureshi, U.S. Rawat and S.L. Mundra. Subject Index. The continuous use of high levels of chemical fertilizers is adversely affecting the sustainability of agricultural production and causing environmental pollution. There is a decline in the productivity of crops, despite the application of optimum levels of fertilizer inputs under assured irrigation. Constraint analysing has identified the declining organic mater status as a probable reason. It is in this context that the supplementation of organic along with chemical fertilizers is a decisive viable strategy. In coming decades a major issue in designing sustainable agriculture system will be the management of soil organic matter and the rational use of inorganic inputs along with animal manures, crop residues, green manures, sewage sludge and food industry wastes. However, since organic wastes cannot meet the total nutrient needs of modern agriculture, integrated use of nutrients from fertilizers and organic wastes seems to be a need of the time. Sustainable plant nutrition to increase food production has been identified as one of the priorities directly linked to land and water management resources in relation to environment. Therefore, the soil health is very important to achieve national food security targets for sustainable growth. Indian agriculture is operating at a net negative balance of plant nutrients at the rate of 8-10 million tonnes/annum. At least 10 million tonnes nutrients should come from organic manures crop residues and bio-degradable wastes. Thus, food security is very much linked with nutrient input. India is endowed with enormous potential for plant nutrients locked up in the bio-degradable wastes. A total quantity of around 875 million tones of these so-called waste material is available in the country, which can supply 18.45 million tones of nutrients annually. This book orients towards recycling of biodegradable organic wastes for improved soil productivity. (jacket).…

Softcover/Taschenbuch. Zustand: Neu. The coupling of an olefin with a carbonyl compound in the presence of an acid catalyst is known as the 'Prins reaction' which normally provides a mixture of 1,3-diols, 1,3-dioxanes, and allylic alcohols. In particular, the coupling of a homoallylic alcohol with a carbonyl compound in the presence of an acid catalyst is known as the 'Prins cyclization', which is a powerful synthetic tool for the stereo selective synthesis of tetrahydropyran scaffolds. On the other hand, aza-Prins cyclization of homoallylic amides with carbonyl compounds is one of the most elegant approaches for the synthesis of piperidine derivatives. In the same way, thia-Prins cyclization of homoallylicmercaptans with aldehydes under the influence of an acid catalyst provides the corresponding thiotetrahydropyrans with a high selectivity. Thus, the Prins cyclization has emerged as a powerful method for the stereo selective synthesis of a wide range of heterocycles such as tetrahydropyran, piperidine and thiotetrahydropyran scaffolds. In this book, we used Prins reaction for synthesis of bioactive natural products such as Polyrhacitide A, Dodoneine, Epi-dodoneine, Euschapholide and Tetraketide.
