Download or read book Achieving Sustainable Crop Nutrition written by Zed Rengel and published by Burleigh Dodds Series in Agric. This book was released on 2019-11-22 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection reviews current research on understanding nutrient cycles, the ways crops process nutrients, the environmental effects of fertilizer use and how this understanding can be used to improve nutrient use efficiency for a more resource-efficient and climate-smart agriculture. Parts 1-3 summarise research on the primary macronutrients: nitrogen, phosphorus and potassium. Chapter review what we know about nutrient cycles, crop nutrient processing, potential environmental effects and ways of optimising nutrient use efficiency (NUE). The fourth section of the book discusses secondary macronutrients and micronutrients including: calcium, magnesium, sulphur, zinc, boron, manganese and molybdenum. The final two parts of the book review research on optimising fertiliser use. Chapters cover topics such as assessing nutrient availability, decision support systems for optimising crop nutrition, advances in site-specific nutrient management and advances in integrated plant nutrient management. Other chapters discuss enhanced efficiency fertilisers, the use of bio-effectors/bio-stimulants, fertigation techniques and the use of organic amendments. With its distinguished editor and international team of expert authors, this will be a standard reference on optimising crop nutrition for the crop science and farming community.

Download or read book Response of Sulphur & Phosphorus in Greengram - Rice Cropping System written by Sanjib Kumar Das and published by LAP Lambert Academic Publishing. This book was released on 2014-11-19 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil health has become a cause of concern for sustainable agricultural production in the new millennium. Use of high analysis fertilizers, heavy sulphur removal by the crops under intensive cultivation & neglect of S replenishment contributed to widespread S deficiencies. Sulphur deficiencies have been reported from 72 countries in the world. Sulphur has a great role in N-fixation by influencing active nodulation in legume & despite the relatively low S requirement of rice, the productivity of these staple food grains may drastically be reduced by an inadequate supply of S. Sulphur has the ability to benefit more than one crop in sequence due to it's significant residual response. Application of higher dose of phosphorus (60 kg P205 /ha ) and increasing levels of sulphur up to 40 kg S/ha proved to be the best in improving the growth, yield attributing characters, grain yield of green gram. Varying levels of residual fertility and basal dose of nitrogen application significantly improved the rice yield and yield attributes. The research data of this book makes it useful reference for researchers, under graduate and post graduate students of agriculture and farming community.

Available in PDF, EPUB and Kindle. Book excerpt: This volume addresses three important agricultural aspects of rice: physical characteristics, physico-chemical characteristics, and the organoleptic aspects. Divided into sections, the book first examines recent trends and advances for higher production and quality improvement, focusing on the effects of climate on rice cultivation and climate-resilient agricultural practices in rice. The volume goes on to cover nutrient management for rice production and quality improvement. Chapters also address weed management and postharvest processing practices for improved rice production. With chapters from renowned scientists, researchers, and professors, this book will be a useful reference for rice researchers working in the area of agronomic practices, postharvest processing, and quality improvement in rice.

Download or read book Agroecosystems of South India written by K. R. Krishna and published by Universal-Publishers. This book was released on 2010 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroecosystems of South India is a unique treatise that deals with the relevance of natural resources, genetic stocks, fertilizers, and agronomic practices on the productivity of agroecoregions. Within the context of this book, an agroecosystem has been defined as a conglomerate of small cropping zones, which may be mono-cropping expanses or intercrops that occur in various geographic regions of South India. South India abounds with several such agroecosystems that encompass field crops, vegetables, cash crops, plantations, and forest species. However, the main emphasis within this volume is restricted to agroecosystems that include major cereals, legumes, and oil seed crops. There are 10 chapters in this volume. The first, on historical aspects, traces important events related to domestication, introduction of crop species, agricultural implements, development of soil fertility and crop husbandry procedures. An introductory chapter on Agroecosystems delineates various agroecoregions of South India. Their classification based on physiography, soils, and climatic parameters have been dealt with in great detail. Descriptions on natural resources such as soils and their fertility conditions; water resources; climatic conditions including precipitation patterns; and crops and their genotypes are available in chapter 2. The impact of soil fertility and nutrient dynamics on ecosystematic functions and productivity of crops in an agroecosystem forms the central piece of discussions within chapters 3 to 9. Historical background, geographical settings, agroclimate, soils, cropping systems, and productivity trends have been provided for each cropping ecosystem. Recent advances and details on aspects of nutrient dynamics, such as soil nutrients, their availability, physico-chemical transformations, nutrient fluxes, inorganic fertilizer supply, organic manures, crop residue recycling, nutrient carry over and nutrient balances/imbalances form the core of each chapter. The impact of beneficial soil microbes such as Rhizobium, Plant Growth Promoting Rhizobacteria and Arbuscular Mycorrhizas, on nutrient dynamics in soil has also been discussed. More recent developments dealing with modeling nutrients in cropping ecosystems, computer based-simulations, precision farming and site-specific nutrient management have been emphasized. Forecasts on the impact of nutrient dynamics on the future course of agroecosystems are also available. Overall, this book is a scholarly edition that aims at providing an excellent exposition of recent developments within various agroecosystems of South India to a global audience. It highlights the importance of soil fertility and nutrient dynamics within agroecosystems to total food grain and fodder production in South India. It will be a useful book to researchers, professors, and students dealing with agriculture, environmental science, ecology, and plant science.
