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 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 There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health.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 Ion Channels and Plant Stress Responses written by Vadim Demidchik and published by Springer Science & Business Media. This book was released on 2010-03-15 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants live in a constantly changing environment from which they cannot physically escape. Plants therefore need signalling and response mechanisms to adapt to new local conditions. The ef?cacy of such mechanisms underlies the plant performance during stress and therefore also impacts greatly on agricultural productivity. M- ulation of ion channel activity not only provides a means for rapid signal generation 2+ but also allows adjustment of cellular physiology. For example, Ca permeable ion 2+ channels can transduce environmental stimuli into Ca -encoded messages which can modify the gene expression. Furthermore, ion channel activity is essential to control cellular ion homeostasis that impacts on plant responses to drought, salinity, pathogens, nutrient de?ciency, heavy metals, xenobiotics and other stresses. This volume focuses on the crucial roles of different types of ion channel in plant stress responses. Functions of ion channels are discussed in the context of mechanisms to relay external and endogenous signals during stress and as mechanisms to regulate cellular ion homeostasis and enzymatic activities in the context of biotic and abiotic stress. The chapters presented cover cation and anion channels located in various cellular compartments and tissues.
Download or read book Mechanisms of Potassium Transport in Plants written by Dev T. Britto and published by . This book was released on 2007 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potassium (K+) is the most abundant ion in the plant cell, and is required for a wide array of functions, ranging from the maintenance of electrical potential gradients across cell membranes, to the generation of turgor, to the activation of numerous enzymes. The majority of these functions depends more or less directly upon the activities and regulation of membrane-bound K+ transport proteins, operating over a wide range of K+ concentrations. Here, we review the physiological aspects of potassium transport systems in the plasma membrane, re-examining fundamental problems in the field such as the distinctions between high- and low-affinity transport systems, the regulation of cellular K+ pools, and the generation of electrical potentials, placing these discussions in the context of recent discoveries in the molecular biology of K+ transport.
Download or read book Potash written by D.E. Garrett and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 744 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potash is the term generally given to potassium chloride, but it is also loosely applied to the various potassium compounds used in agriculture: po tassium sulfate, potassium nitrate or double salts of potassium and magne sium sulfate (generally langbeinite, K S0 • 2MgS0 ). Sometimes the var 2 4 4 ious compounds are differentiated by the terms muriate of potash, sulfate of potash, etc. When referring to ores, or in geology, all of the naturally found potassium salts are called "potash ores". However, originally potash referred only to crude potassium carbonate, since its sole source was the leaching of wood ashes in large pots. This "pot ash" product was generally recovered from near-seacoast plants, such as the saltwort bush, whose ashes were richer in potassium than sodium carbonate. Inland plant's ashes were generally higher in sodium carbonate, giving rise to the word alkali from the Arabic word for soda ash, al kali. The term was then carried over after potassium was discovered to form the latin word for it, kalium. The recovery of potash from ashes became a thriving small cottage industry throughout the world's coastal areas, and developing economies, such as the early set tlers in the United States were able to generate some much-needed income from its recovery and sale. This industry rapidly phased out with the advent of the LeBanc process for producing soda ash in 1792, and the discovery about the same time of the massive sodium-potassium nitrate deposits in the Atacama Desert of Chile.

Download or read book Cell Biology of Metals and Nutrients written by Rüdiger Hell and published by Springer Science & Business Media. This book was released on 2010-03-10 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants are composed of 17 essential and at least 5 beneficial elements, and these must be taken up as metal or nutrient ions to allow for growth and cell division. Much effort has been devoted to studying the physiology and biochemistry of metals and nutrients in plants. The aspect of cell biology, however, is an emerging new field and much needs to be learned about sensing, long-distance communication within plants, and cellular signal transduction chains in response to environmental stress. Cellular malfunction and consequently disease result when any of the key steps in metal and nutrient homeostasis are disrupted. Working together, leading experts in their respective fields provide a new concept that reaches beyond plant nutrition and plasmalemma transport into cellular physiology. Each chapter contains basic information on uptake, physiological function, deficiency and toxicity syndromes, long-distance and intracellular transport. The discussion is devoted to metals and nutrients where recent progress has been made and highlights the aspects of homeostasis and sensing, signaling and regulation, drawing parallels to other organisms including humans. Finally, the book identifies gaps in our current knowledge and lays out future research directions.

Download or read book Role of Potassium in Plants written by Girdhar K. Pandey and published by Springer Nature. This book was released on 2020-06-15 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potassium (K+) is an essential mineral macronutrient abundantly present in the cytosol which, unlike other macronutrients, is not metabolized and does not integrate into macromolecules. Compared to animal cells, K+ is more abundantly present in plant cells. Overall performance of the plant, and operation of metabolic machinery depends upon intracellular K+ homeostasis (K+ uptake and efflux) via K+ channels and transporters acting as mediators of cellular responses during plant development. Unlike animals, plants lack sodium/K+ exchangers; plant cells have developed unique transport systems for K+ accumulation and release. In Arabidopsis thaliana, 71 K+ channels and transporters have been identified and categorized into six families. Plant adaptive responses to several abiotic and biotic stresses are mediated by regulation of intracellular K+ homeostasis. In this report, we highlight the role of K+ in abiotic and biotic stresses, features of channels and transporters responsible for its homeostasis along with its evolutionary relationship, perception and sensing mechanisms, and K+ deficiency triggering different signaling cascades. Overall, this book covers the role of K+ in plants would be significantly helpful to research, academic community as well as students to understand the one of the major attributes of plant biology.

Download or read book Potash Use and Dynamics in Agriculture written by Abdul Wakeel and published by Springer Nature. This book was released on 2021-11-30 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the use and dynamics of potassium fertilizers in agriculture. It explores potassium dynamics in soil, phytoavailability, uptake and translocation in crop plants, impact of potassium fertilizers on quality of agricultural produce. Potassium is an essential plant nutrient that has long been overlooked in agriculture of many developing countries. In most of the agro-ecosystems of such countries, potassium balance is negative because its application seldom matches with crop removal. Agro-technicians lack enough skills and resources to promote the right source of fertilizer at the right rate, time and place to facilitate profitable farming. There is a need for farmers to update their farming practices so as to improve the crop yield and quality under unfavorable climatic conditions. Correct application of potassium fertilizers is directly linked with increased crop yield per unit land area in most of the developing countries. Therefore this book fills the gap in the information and provide the readers with latest updates on use of potassium fertilizers. This book contains latest information relevant for graduate students, progressive farmers, extension worker, early career researchers, and policy makers.
