Available in PDF, EPUB and Kindle. Book excerpt: Growth chamber experiments were conducted from 1992 to 1994 on a calcareous silty clay loam soil (pH $\approx$ 7.9) low in levels of available phosphorus. A number of different band geometries were assessed for their effect on the efficiency of P utilization from applied monoammonium phosphate (MAP). Ammonium and magnesium sulfates, urea, and organic amendments (lignosulfonates) were also incorporated into P fertilizer bands to study their effect on uptake of applied P by plants. The MAP was labelled with the radioisotope $\sp{32}$P in order to determine utilization of fertilizer P specifically. Dry matter yields and total P uptake were also measured. Canola was very efficient at utilizing applied P, with no apparent benefit from increased area of application or dual banding with N. However, fertilizer P uptake by wheat increased slightly with area of application, Dual banding the P fertilizer with N or MgSO$\sb4$ stimulated P uptake by wheat. Ammonium sulfate was most effective in increasing P utilization. Urea initially slowed uptake, but increased P utilization at later stages of plant growth. Studies were also conducted using very wide band widths. Labelled MAP was randomly applied in powdered form to several points within the bands, to simulate granular applications. Ammonium sulphate was dual banded with the MAP granules (placed in direct contact) or randomly scattered within the band. Fertilizer P uptake declined slightly as band width increased from 2.5 to 15 cm, particularly at earlier growth stages. Dual banding with ammonium sulphate improved P fertilizer utilization and yield. (Abstract shortened by UMI.).

Download or read book Interfacial Chemistry of Rocks and Soils written by Noémi M. Nagy and published by CRC Press. This book was released on 2021-10-28 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the basic interactions that take place between geological materials and different substances is the first step in understanding the effects of adsorption and other interfacial processes on the quality of rocks and soils, and on driving these processes towards a beneficial or neutral result. Interfacial Chemistry of Rocks and Soils examines the different processes at solid and liquid interfaces of soil and rock, presenting a complete analysis that emphasizes the importance of chemical species on these interactions. This Second Edition features novel results in the field and expanded coverage of the kinetics of interfacial processes. New content includes models of heterogeneous isotope exchange, sorption isotherms for heterovalent cation exchange, as well as sorption of anions by chemically modified clays. Summarizing the results and knowledge of the authors’ research in this field over several decades, this volume: Explores the individual components of the studied systems: the solid, the solution, and the interface Discusses the characteristics and thermodynamics of the interface Profiles the most important analytical methods in the study of interfacial processes Demonstrates transformations initiated by interfacial processes Outlines avenues of treatment that may solve geological, soil science, and environmental problems Drawn chiefly from the authors’ years of research at the Imre Lajos Isotope Laboratory in the Department of Physical Chemistry at the University of Debrecen in Hungary, this book discusses chemical reactions on the surfaces/interfaces of soils and rocks; examines the role of these processes in environmental, colloid and geochemistry; and explores the effects on agricultural, environmental and industrial applications.
