Download or read book Phosphorus Adsorption Characteristics in Selected Soils of Pakistan written by Ayaz Mehmood and published by LAP Lambert Academic Publishing. This book was released on 2013 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is growth limiting nutrient and deficient in most soils of the world. Research was conducted on five soil series of Pakistan differing in soil properties. Phosphorus adsorption isotherms were developed and fitted to Langmuir and Freundlich equations to describe P adsorption process. The study suggests that the oxides of iron and aluminum are the main adsorbent at low P concentration, normally applied in agricultural soils and soil CaCO3 play role at high P level. This book is recommended for soil science community working on P chemistry.

Download or read book Phosphate in Soils written by H. Magdi Selim and published by CRC Press. This book was released on 2018-10-08 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edited by One of the Best Specialists in Soil Science Recent studies reveal that Phosphorus (P) in the form of phosphate, a macronutrient essential for plant growth, and crop yields can influence the bioavailability, retention, and mobility of trace elements, metal(loid)s, and radio nuclides in soils. When this occurs, phosphates can affect the dynamics of heavy metals and influence soil characteristics, impacting soil mobility and toxicity. Phosphate in Soils: Interaction with Micronutrients, Radionuclides and Heavy Metals utilizes the latest research to emphasize the role that phosphate plays in enhancing or reducing the mobility of heavy metals in soil, and the soil-water-plant environment. It provides an in-depth understanding of each heavy metal species, and expands on phosphate interactions in geological material. Composed of 12 chapters, this text: Provides an overview of the reactions of metal(loid)s and common P compounds that are used as fertilizer in soils Emphasizes the effect of phosphorus on copper and zinc adsorption in acid soils Discusses findings on the influence of phosphate compounds on speciation, mobility, and bioavailability of heavy metals in soils as well as the role of phosphates on in situ and phytoremediation of heavy metals for contaminated soils Places emphasis on the influence of phosphate on various heavy metals species in soils, and their solubility/mobility and availability Provides extensive information on testing various high phosphate materials for remediation of heavy metal, micronutrients, and radionuclides contaminated sites Explores the reactivity of heavy metals, micronutrients and radionuclides elements in several soils Presents a case study illustrating various remediation efforts of acidic soils and remediation of Cu, Zn, and lead (Pb) contaminated soils around nonferrous industrial plants Emphasizes the significance of common ions (cations and anions) on phosphate mobility and sorption in soils, and more The author includes analytical and numerical solutions along with hands-on applications, and addresses other topics that include the transport and sorption modeling of heavy metals in the presence of phosphate at different scales in the vadose zone.

Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this research were to study the P sorption characteristics of soils and the effects of pH and of cation type and concentration on P sorption by soils and minerals. In an attempt to characterize the nature and properties of P sorption sites of soils, P sorption isotherms in a 0.1 N NaC1 system were obtained for six limed and unlimed agricultural soils from Rio Grande do Sul, Brazil. The equilibration time was 48 hours and the concentration of P in the final solution varied from near zero to 20 ugP/ml. Langmuir plots (c/x vs c) of the data resulted in curvilinear and/or multi-straight line relationships suggesting the presence of 2 or more populations of sites with different affinities for P. An iterative multiple regression analysis computer program that assumes that each population of site follows the Langmuir equation was used to analyze the sorption data. Three populations of sites with different affinities for P were detected and the Langmuir constants, k (binding energy term) and b (sorption maximum) were estimated for each population of sites. The median and range for values of k (ml/ug P) and b (ugP/g) for the three populations of site were in decreasing order of affinity for P:K1 = 140, (40-2870) and b1=120 (8-370); K2=2.4, (0.63-10) and b2=174, (25-704); and K3 =0.095, (0.051-0.27) and b3=763 (131-1460). On the average, the total number of P sorption sites (total) was made up of 10% of sites with high affinity for P, 22% with moderate and 68% with low affinity ...

This book was released on 2012-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of organic residues as a means of maintaining and increasing soil fertility is of long-standing. This tradition has been somewhat neglected since the introduc tion of mineral fertilizers at low cost. More and more farmers and scientists are now showing renewed interest in the proper and effective use of org~tnic residues, composts and other recycled organic additives. The role and function of organic amendments in modern agricultural systems have become topics of major interest in the scientific and agricultural communities. Research work on residue disposal has provided new concepts on the interaction between organic components and soils as well as new handling technologies (e. g. pelletizing of organic residues). The trend to conserve energy has led scientists to study the minimal tillage system, to find ways of replacing conventional inorganic fertilizers with natural organic prod ucts or microbial preparations, and to develop new composting methods. The drive to achieve higher yields in commercial greenhouse farming has led to a search for optimum substrates as growth media and for improved management techniques. This has led to the introduction of organic substitutes for peat, nota bly those originating from agricultural wastes. Another important aspect is the current interest in organic farming, where use of synthetic chemicals is avoided or prohibited. An increasing percentage of the population in highly developed countries is willing to pay premium prices for food produced on soils where inorganic fertilizers and other agricultural chemicals have not been used.

This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is an essential nutrient controlling plant growth and it is fundamental for the productivity of agricultural ecosystems; however, excess P in an environment causes eutrophication. Long-term accumulation of P in soils may cause environmental problems for decades even after reducing the anthropogenic P input into agro-ecosystems. A better understanding of the processes and characteristics that influence P adsorption, desorption, and solute transport in porous media is helping in assessing the availability of P for a sustainable agricultural production and productivity.eng
