Download or read book Microorganisms for Green Revolution written by Deepak G. Panpatte and published by Springer. This book was released on 2017-12-07 with total page 443 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses basic and applied aspects of two nexus points of microorganisms in agro-ecosystems, namely their functional role as bio-fertilizers and bio-pesticides. Readers will find detailed information on all of the aspects that are required to make a microbe “agriculturally beneficial.” A healthy, balanced soil ecosystem provides a habitat for crops to grow without the need for interventions such as agro-chemicals. No organism in an agro-ecosystem can flourish individually, which is why research on the interaction of microorganisms with higher forms of life has increasingly gained momentum in the last 10-15 years. In fact, most of plants’ life processes only become possible through interactions with microorganisms. Using these “little helpers” as a biological alternative to agro-chemicals is a highly contemporary field of research. The information presented here is based on the authors’ extensive experience in the subject area, gathered in the course of their careers in the field of agricultural microbiology. The book offers a valuable resource for all readers who are actively involved in research on agriculturally beneficial microorganisms. In addition, it will help prepare readers for the future challenges that climate change will pose for agriculture and will help to bridge the current gaps between different scientific communities.

Download or read book Modification of Nitrogen Fertilisers Using Inhibitors written by Catherine J. Watson and published by . This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: When fertilizer nitrogen (N) is applied to soil it is not used efficiently and plant N uptake is seldom greater than 50% of the N applied. One of the reasons for poor N use efficiency is high losses from the plant-soil system by ammonia (NH3) volatilization, during nitrification and by leaching, erosion, surface runoff and denitrification. The loss of N represents an economic loss to farmers and has environmental implications for water quality and greenhouse gas emissions. Stabilised N fertilizers (urease and nitrification inhibitors) have received considerable attention recently due to their potential to lower N losses to the environment and increase crop yields. However, the efficacy of urease and nitrification inhibitors can be quite variable depending on the crop, soil properties, climatic and management factors. Many compounds have been evaluated as urease or nitrification inhibitors however, few meet the requirements of being effective at low concentrations, non toxic, stable, inexpensive and compatible with standard N fertilizers. Urease inhibitors delay the rate of urea hydrolysis to ammonium-N (NH4+-N) and hence prevent localised zones of high pH and NH4+-N concentrations in soil, which are conducive to NH3 volatilization. They are expected to be most beneficial on soils where NH3 volatilization from urea fertilizer is high. The urease inhibitor N-(n-butyl) thiophosphoric triamide (trade name Agrotain(r)) is the most successful commercially, where it has been shown to lower NH3 volatilization from surface-applied urea and increase yields on a wide range of crops. Agrotain is now licensed or sold in over 70 countries worldwide, in both agricultural and amenity markets.
Download or read book Ureases written by Rodrigo Ligabu Braun and published by Elsevier. This book was released on 2024-02-16 with total page 483 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ureases: Foundations, Classes, and Applications provides a thorough, practical analysis of ureases—enzymes of growing relevance across a range of biotechnological applications and drug discovery. Unique in many aspects, ureases are one of the few enzymes to have nickel in their active sites. Ureases covers all aspects of this enzymatic class. Starting with foundational overview, the book discusses historical urease research and the current state, from basic biochemistry to the use of ureases as hallmarks in enzymology, crystallography, and bioinorganic chemistry. The different classes of ureases, structurally diverse but chemically equivalent, are individually discussed. The multi-protein, multi-step activation of ureases (with chemical modification of residues, transport, and transfer of nickel ions) are examined in-depth, along with the catalytic mechanisms of ureolysis and its inhibitors. The final two sections of the book address multiple applications of ureases in health and biotechnology, respectively, going from gastric ulcer treatment to architectural uses in buildings and engineering. Future applications and next steps in research are also considered. Considers fundamental aspects of urease biochemistry, ureolysis and urease inhibitors Discusses urease research across a range of applications, from drug discovery to biosensors, water purification, architecture and the food industry Features chapter contributions from international leaders in the field
Download or read book Nutrient Use Efficiency from Basics to Advances written by Amitava Rakshit and published by Springer. This book was released on 2014-12-26 with total page 417 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses in detail multifaceted approaches to boosting nutrient use efficiency (NUE) that are modified by plant interactions with environmental variables and combine physiological, microbial, biotechnological and agronomic aspects. Conveying an in-depth understanding of the topic will spark the development of new cultivars and strains to induce NUE, coupled with best management practices that will immensely benefit agricultural systems, safeguarding their soil, water, and air quality. Written by recognized experts in the field, the book is intended to provide students, scientists and policymakers with essential insights into holistic approaches to NUE, as well as an overview of some successful case studies. In the present understanding of agriculture, NUE represents a question of process optimization in response to the increasing fragility of our natural resources base and threats to food grain security across the globe. Further improving nutrient use efficiency is a prerequisite to reducing production costs, expanding crop acreage into non-competitive marginal lands with low nutrient resources, and preventing environmental contamination. The nutrients most commonly limiting plant growth are N, P, K, S and micronutrients like Fe, Zn, B and Mo. NUE depends on the ability to efficiently take up the nutrient from the soil, but also on transport, storage, mobilization, usage within the plant and the environment. A number of approaches can help us to understand NUE as a whole. One involves adopting best crop management practices that take into account root-induced rhizosphere processes, which play a pivotal role in controlling nutrient dynamics in the soil-plant-atmosphere continuum. New technologies, from basic tools like leaf color charts to sophisticated sensor-based systems and laser land leveling, can reduce the dependency on laboratory assistance and manual labor. Another approach concerns the development of crop plants through genetic manipulations that allow them to take up and assimilate nutrients more efficiently, as well as identifying processes of plant responses to nutrient deficiency stress and exploring natural genetic variation. Though only recently introduced, the ability of microbial inoculants to induce NUE is gaining in importance, as the loss, immobilization, release and availability of nutrients are mediated by soil microbial processes.

Download or read book The Biological Chemistry of Nickel written by Deborah Zamble and published by Royal Society of Chemistry. This book was released on 2017-04-04 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal ions play key roles in biology. Many are essential for catalysis, for electron transfer and for the fixation, sensing, and metabolism of gases. Others compete with those essential metal ions or have toxic or pharmacological effects. This book is structured around the periodic table and focuses on the control of metal ions in cells. It addresses the molecular aspects of binding, transport and storage that ensure balanced levels of the essential elements. Organisms have also developed mechanisms to deal with the non-essential metal ions. However, through new uses and manufacturing processes, organisms are increasingly exposed to changing levels of both essential and non-essential ions in new chemical forms. They may not have developed defenses against some of these forms (such as nanoparticles). Many diseases such as cancer, diabetes and neurodegeneration are associated with metal ion imbalance. There may be a deficiency of the essential metals, overload of either essential or non-essential metals or perturbation of the overall natural balance. This book is the first to comprehensively survey the molecular nature of the overall natural balance of metal ions in nutrition, toxicology and pharmacology. It is written as an introduction to research for students and researchers in academia and industry and begins with a chapter by Professor R J P Williams FRS.
