Book Description
Excess phosphorus applied to soils with low P adsorption capacities can potentially enter surface water via leaching and subsurface transport, thereby negatively impacting surface water quality. Currently proposed best management practices for inhibition of P leaching are limited to reducing the P application rates, which can decrease the economic viability of animal producers. The protection of water quality and sustainability of animal production are dependent on accurate descriptions of waste and soil management effects on P leaching. Development of new best management practices will benefit both the environment and animal producers. This requires further data and research to adequately describe the risk of P loss via leaching and determine the effects of new best management practices on P leaching. The objectives of this research are to: 1) monitor P concentrations in the soil solution of soils with long-term histories of swine lagoon effluent application and relate these P concentrations to easily quantifiable soil properties, 2) modify the GLEAMS (Groundwater Loading Effects of Agricultural Management Systems) model P subroutines to more accurately reflect P sorption/desorption and validate the modified model with collected field data, 3) use the validated version of GLEAMS to determine cropping system and waste management effects on long-term P leaching losses, and 4) evaluate the use of alum (Al2(SO4)3·14H2O) additions to soil and waste as a best management practice to reduce P leaching. Soil solution P concentrations were monitored at 45, 90, and 135 cm depths for 20 months in Autryville and Blanton soils under grazed pasture that had received swine waste for more than 20 years. Maximum soil solution P concentrations at 45 cm were in excess of 18 mg L−1 in both soils. Soil solution P concentrations at 90 cm in the Blanton soil were similar to that at 45 cm, indicating low P sorption. However, soil solution P conce.

Phosphate in Soils
Author: H. Magdi Selim
Publisher: CRC Press
ISBN: 148223680X
Category : Nature
Languages : en
Pages : 381
Book Description
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.
