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.

Download or read book A Laboratory Investigation of Phosphorus Removal Using Engineered Soils in Bioretention Columns written by Clint Gregory and published by . This book was released on 2016 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Stormwater runoff from rainfall events can contain pollutants that are carried into nearby streams and lakes. One constituent of concern is phosphorus, which can be present in fertilizer used in agricultural and home gardening applications and in soil particles. One technique for treating stormwater is bioretention, which involves capturing runoff and infiltrating it through natural or engineered soil beds. The effectiveness of different engineered soil mixes and underdrain amendments at removing phosphorus was the focus of this research. Of particular concern was the ability of underdrain media to reduce the leaching of phosphorus from compost-based bioretention soil media (BSM). The BSM used in this study was composed of 60-70% sand and 30-40% of compost with an infiltration rate of at least 5 inches per hour. Seven, four-inch diameter columns were filled with BSM or BSM plus topsoil to a depth of 18 inches and an eighth was filled to 30 inches. Adding topsoil reduces the compost fraction in the BSM. Various underdrain materials, including pea gravel, crushed limestone, and activated alumina, were tested to investigate their phosphorus adsorptive potentials. Activated alumina is a synthetic aluminum-based adsorptive material used for phosphorus removal. It was incorporated into the underdrain of two columns as a 4-inch layer on top of a pea gravel base. The other underdrains were composed of 12 inches of gravel or limestone. The columns were dosed equally with a synthetic stormwater mixture at both low and high rates to simulate varied rainfall conditions. Most columns leached phosphorus from the BSM into the effluent. The columns with an activated alumina layer, however, showed little or no leaching and in some test runs net removal of phosphorus (compared to the influent concentration) was observed. When deeper BSM was used or the BSM was mixed with topsoil, phosphorus leaching increased. The unexpected results for the BSM plus topsoil columns can be explained by a high proportion of compost in the topsoil used. In some columns the media was washed with tap water prior to the experimental runs. Washing the columns removed some particles with a size larger than 0.45 microns, but not all. As a result, phosphorus leaching was reduced, but not eliminated, by media washing except in the columns containing activated alumina. The results from this laboratory experiment were incorporated into the design of a larger experimental project sponsored by the State of California with Proposition 84 funds.

Download or read book Soil Phosphorus written by Rattan Lal and published by CRC Press. This book was released on 2016-09-19 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus is an essential plant nutrient, but global population growth has dramatically reduced the availability of phosphorus fertilizer resources. Despite this scarcity, there remain numerous problems associated with the excessive and inappropriate use of phosphorus leading to non-point source pollution and eutrophication of natural waters. Identifying appropriate systems for managing soil phosphorus and reducing the risks of eutrophication are needed to minimize the environmental risks. This book focuses on the availability and recycling of phosphorus; regulatory and policy issues of sustainable phosphorus use; and water quality management in agroecosystems pertaining to phosphorus. Sections are dedicated to global phosphorus reserves; cycling and pathways of phosphorus; phosphorus in agriculture; human dimensions and policy intervention; and research and development priorities. Phosphorus is a finite but crucial resource and is an essential element to all life. Sub-optimal availability and nutrient imbalance in the root zone can adversely impact plant growth, and the quality of food and feed grown on these soils. However, the proven reserves of phosphorus can hardly be adequate for a few centuries only. Yet, its misuse and mismanagement has caused severe problems of eutrophication of water and pollution of the environment. Thus, judicious management of soil phosphorus is essential. This volume is specifically devoted to availability and recycling of phosphorus, regulatory/policy issues of sustainable use of phosphorus, and management in agroecosystems in the context of maximizing the use efficiency and minimizing the environmental risks of water quality.

This book was released on 1988-10-31 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: These volumes present the main classes of useful laboratory model systems used to study microbial ecosystems, with emphasis on the practical details for the use of each model. The most commonly used model, the homogeneous fermenter, is featured along with linked homogeneous culture systems, film fermenters, and percolating columns. Additionally, gel-stabilized culture systems which incorporate molecular diffusion as their main solute transfer mechanism and the microbial colony are explained. Chapters comparing model systems with "microcosms" are included, along with discussions of the value of computer models in microbial ecosystem research. Highlighted is a global discussion of the value of laboratory models in microbial ecology.
