Download or read book Phosphorus in Soils and Plants written by Naser A. Anjum and published by BoD – Books on Demand. This book was released on 2024-01-31 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%–30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil–water–sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant–microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Problem of Phosphate Fertilizers: Their Relation to the Phosphate-Supplying Power of the Soil and to the Requirements of Farm Crops The phosphate-supplying power of any given soil is not determined primarily by its total phosphorus content, for much of the phosphates are in forms only very slowly available to plants. Comparatively poor soils contain in the upper 15 to 18 inches, the depth to which the feeding roots penetrate in large numbers, enough phosphorus to pro vide for maximum crops for upward of a century if all the phosphorus were accessible to the growing plants; crops at more probable yields would be supplied for two or three centuries.

Download or read book Phosphorus in Agriculture 100 Zero written by Ewald Schnug and published by Springer. This book was released on 2016-06-14 with total page 357 pages. Available in PDF, EPUB and Kindle. Book excerpt: The title ‘Phosphorus in Agriculture: 100 % Zero’ is synonymous for make-or-break. And it stands up to the promise. This book sends an important message as it delivers background information, intrinsic hypotheses, validation approaches and legal frameworks, all for balanced phosphorus fertilization in agriculture. This implies firstly that the phosphorus requirement of crop is fully satisfied by applying exclusively fertilizers which contain the nutrient in completely available form. Secondly, environmental demands through eutrophication and hazardous contaminants must not be compromised. The book identifies equally knowledge gaps and deficits in the transformation and implementation of research into practice. Bottom line is that research delivers the tools for a sustainable phosphorus management while legal frameworks are insufficient.

Download or read book Dietary Phosphorus written by Jaime Uribarri and published by CRC Press. This book was released on 2017-09-27 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus is an essential nutrient that occurs in almost all foods and is important for many normal physiological functions. In a typical Western diet, it is not harmful, but does adversely affect tissues in the body when consumed in excess or deficiency. This book provides a comprehensive review of various aspects of phosphorus in relation to human nutritional needs. Sections cover phosphorus nutrition and dietary issues; health risks associated with excess phosphorus intake that exceeds requirements; phosphorus intake in populations at risk; regulatory challenges and policy approaches; and environmental impacts of phosphates in the modern food supply. This book challenges the long held ideas that high dietary phosphorus intake beyond nutritional requirements is safe and the natural supply of phosphorus critical to agricultural and human food production is endless. Controversy surrounds the claim that largely unrestricted use of phosphorus in all aspects of food production from farm to fork increases dietary phosphorus intake and irretrievable environmental loss, both of which harm human and environmental health. The book editors have joined together experts in basic, medical, environmental, nutritional, and food science to explore the validity of these claims of harm from high intakes and the unchecked use of phosphorus in the global food supply. Despite the essential need for adequate phosphorus over all stages of plant, animal and human life, the growing evidence points to a worldwide increase in dietary phosphorus intake far beyond nutrient requirements, significant association with chronic disease risk even when renal function is not compromised, and the increase in environmental loss with crop run-off, animal husbandry, and unretrieved phosphorus from human waste. This current evidence alludes to a depleted, unsustainable natural supply of phosphorus, hazardous environmental pollution of lakes and waterways, and significant increases in the risk of kidney, skeletal, and other serious illnesses in humans in the future if action is not taken now.

Download or read book Plant Adaptations to Phosphate Deficiency written by Alex Joseph Valentine and published by Frontiers Media SA. This book was released on 2021-05-18 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphate is an essential mineral to all plants, and its availability in soils is an increasing challenge for agriculture. Phosphate is abundant in soils but its biological availability is often low due to the complexes that it forms with soil minerals and compounds. The biological availability of Phosphate is further reduced in acidic soils, which represent approximately 40% of earth’s arable agricultural lands. Agricultural systems compensate Phosphate deficiency with fertilizers coming from the mining of rock phosphate, which is estimated to exhaust within the next 50 years. For these reasons, Phosphate limitations in natural and agricultural ecosystems is going to become a global problem, and we urgently need to better understand how plants respond to Phosphate deficiency.
