Available in PDF, EPUB and Kindle. Book excerpt: The population of the world is expected reach 6 bilion by the year 2000 (up from 4.7 bilion in 1983). This rapid expasion has created the need for much more food that has to be produced by opening up new lands for farming. The crops (which are the basis of nearly all of man's food) take their food, the chemical elements that are essential nitrients, from the soil in which they are rooted. In centuries past the soils supplied enough nutrients to maintain traditional agricultura systems.

Download or read book Improving Potassium Recommendations for Agricultural Crops written by T. Scott Murrell and published by Springer Nature. This book was released on 2020-12-14 with total page 466 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 There was general agreement that the potassium recommendations currently in general use are oversimplified, outdated, and jeopardize soil, plant, and human health.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 331 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 Improved Crop Quality by Nutrient Management written by Dilek Anaç and published by Springer Science & Business Media. This book was released on 2007-11-23 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Emphasis in agricultural production has shifted from mere quantity to quality products. Practical experience and scientific investigations have shown that, of the various culture measures, balanced fertilization above all exerts a considerable influence on the quality of agricultural products. Simply adding more of what the crop has already absorbed to capacity is unproductive, expensive, wasteful and damaging to the environment. Therefore, balanced crop nutrition increases crop quality, safeguards natural resources and brings benefit to the farmer. Otherwise rapid population growth and severe urbanization will exhaust our natural resources.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The book encompasses different Agriculturally Important microorganisms (AIMs), mechanisms of action and modes of application for sustainable agriculture. The potential of microbes in nitrogen fixation, solubilizing nutrients like phosphorous, Potassium, tolerance to etc. are the major strength of the book. There is relatively a new frontier, use of Plant Growth Promoting Rhizobacteria(PGPR)in enhancing crop productivity. These microbes inhabit at the rhizospheric region of the root and facilitate plant growth through a variety of direct and indirect mechanisms. These PGP have been identified to solubilize phosphate, Potassium, Zinc, produce siderophore, IAA, Hydrogencyanide, fix ammonia and many more. Today, such microbes are extensively studied not only as a biofertilizer or fortification of nutrient to the plant, but also a potential agent to decrease application of chemical fertilizer and other agrochemicals. The book also gives an insight to this aspect also. Last but not the least,a light has been thrown on use and application of nano-biofertilizer for sustainable agriculture.

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.
