Download or read book Improving Potassium Recommendations for Agricultural Crops written by T. Scott Murrell and published by Springer. This book was released on 2022 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book highlights concepts discussed at two international conferences that brought together world-renowned scientists to advance the science of potassium (K) recommendations for crops. There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health. Accordingly, this book puts forward a significantly expanded K cycle that more accurately depicts K inputs, losses and transformations in soils. This new cycle serves as both the conceptual basis for the scientific discussions in this book and a framework upon which to build future improvements. Previously used approaches are critically reviewed and assessed, not only for their relevance to future enhancements, but also for their use as metrics of sustainability. An initial effort is made to link K nutrition in crops and K nutrition in humans. The book offers an invaluable asset for graduate students, educators, industry scientists, data scientists, and advanced agronomists.

Download or read book Potassium Solubilizing Microorganisms for Sustainable Agriculture written by Vijay Singh Meena and published by Springer. This book was released on 2016-06-27 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: The potassium solubilizing microorganisms (KSMs) are a rhizospheric microorganism which solubilizes the insoluble potassium (K) to soluble forms of K for plant growth and yield. K-solubilization is carried out by a large number of saprophytic bacteria (Bacillus mucilaginosus, B. edaphicus, B. circulans, Acidothiobacillus ferrooxidans, Paenibacillus spp.) and fungal strains (Aspergillus spp. and Aspergillus terreus). Major amounts of K containing minerals (muscovite, orthoclase, biotite, feldspar, illite, mica) are present in the soil as a fixed form which is not directly taken up by the plant. Nowadays most of the farmers use injudicious application of chemical fertilizers for achieving maximum productivity. However, the KSMs are most important microorganisms for solubilizing fixed form of K in soil system. The KSMs are an indigenous rhizospheric microorganism which show effective interaction between soil-plant systems. The main mechanism of KSMs is acidolysis, chelation, exchange reactions, complexolysis and production of organic acid. According to the literature, currently negligible use of potassium fertilizer as chemical form has been recorded in agriculture for enhancing crop yield. Most of the farmers use only nitrogen and phosphorus and not the K fertilizer due to unawareness that the problem of K deficiency occurs in rhizospheric soils. The K fertilizer is also costly as compared to other chemical fertilizers.

Download or read book Interactions at the Soil Colloid written by G.H. Bolt and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 605 pages. Available in PDF, EPUB and Kindle. Book excerpt: About 20 years ago the emphasis in soil chemistry research switched from studies of problems related to scarcities of plant nutrients to those arising from soil pollutants. The new problems have come about because of the excessive uses of fertilizers, the inputs from farm and industrial wastes, the widespread applications of anthropogenie xenobiotic chemicals, and the deterioration of soil structure resulting from certain modern agriculture practises. The International Society of Soil Science (ISSS) recognized these problems and challenges. A provisional Working Group was set up in 1978 to focus attention on soil colloids with a view to understanding better the interactions wh ich take place at their surfaces. It was recognized that these interactions are fundamental to problems of soil fertility, as weIl as to those of soil pollution. After the group had received the official support of ISSS at its 12th International Congress in New Delhi in 1982 it set as its priority the assembling and evaluation of information, relevant to the soil and environmental sciences, concerning the composition and structure of soil colloids. Prior to that aseries of Position Papers were published in the Bulletin of the International Society of Soil Science (Vol. 61, 1981) outlining the state of knowledge about the composition and properties of soil colloids.
Download or read book Soil Remediation and Plants written by Khalid Hakeem and published by Academic Press. This book was released on 2014-08-29 with total page 771 pages. Available in PDF, EPUB and Kindle. Book excerpt: The soil is being contaminated continuously by a large number of pollutants. Among them, heavy metals are an exclusive group of toxicants because they are stable and difficult to disseminate into non-toxic forms. The ever-increasing concentrations of such pollutants in the soil are considered serious threats toward everyone's health and the environment. Many techniques are used to clean, eliminate, obliterate or sequester these hazardous pollutants from the soil. However, these techniques can be costly, labor intensive, and often disquieting. Phytoremediation is a simple, cost effective, environmental friendly and fast-emerging new technology for eliminating toxic heavy metals and other related soil pollutants. Soil Remediation and Plants provides a common platform for biologists, agricultural engineers, environmental scientists, and chemists, working with a common aim of finding sustainable solutions to various environmental issues. The book provides an overview of ecosystem approaches and phytotechnologies and their cumulative significance in relation to solving various environmental problems. - Identifies the molecular mechanisms through which plants are able to remediate pollutants from the soil - Examines the challenges and possibilities towards the various phytoremediation candidates - Includes the latest research and ongoing progress in phytoremediation

Download or read book Millet Rhizosphere written by Ramesh Namdeo Pudake and published by Springer Nature. This book was released on 2023-09-11 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: This edited volume is the first book that explicitly explains the link between the extraordinarily small-scale microbial processes and the growth and yield attributes of millet crops. This book includes chapters emphasizing on the effects of rhizosphere biology on long-term millet crop management. Millets are a collection of small-grained cereal grasses that are grown for human carbohydrate needs. They are among the oldest crops, mainly divided into two groups: major and small millets based on seed size. Major millets are composed of sorghum (Sorghum bicolor) and pearl millet (Pennisetum glaucum); while small millets are composed of six species that includes finger millet (Eleusine coracana (L.)), little millet (Panicum sumatrense), kodo millet (Paspalum scrobiculatum (L.)), foxtail millet (Setaria italica (L.)), barnyard millet (Echinochloa frumentacea (L.)), and proso millet (Panicum miliaceum (L.). These crops are earlier considered as orphan crops, but recently due to their nutritional values it is gaining the importance. Various reports are published based on role of rhizosphere on growth and health of these crops. The rhizosphere being a dynamic interface among the plant roots and soil microbes provides a number of advantages to the millets too. The soil properties in rhizospheric region are also different as compared to the bulk soil. This book discovers the functional attributes of rhizosphere in promoting the healthy growth of millet crop and achieving higher yield during the changing climatic condition. This book is of interest to university teachers, scientists working in the millets, and policymakers in agricultural departments. Also, the book serves as additional reading material for undergraduate and graduate students of agriculture, biotechnology, microbiology, genetics, and soil science.
