Book Description
Excerpt from Studies With Radioactive Phosphorus in Soils of the Western States, 1950-53 The Publications Committee decided to publish a summary of these reports in one publication. In order to make the summarized data as useful as possible, the Committee asked H. B. Peterson, Head, Department of Agronomy, Utah State Agricultural College, to prepare a discussion on the phosphate status and prob lems in western soils, and C. O. Stanberry, Soil and Water Conservation Research Division, U. S. Department of Agriculture, Yuma, Ariz., to prepare a discussion on principles established by previous experimentation. These, as well as discus sions and recommendations that appear justified from the data presented, are included to supplement the compilation of data. The Committee has attempted to credit States and individuals who sponsored and presented data accumulated at the several locations in the Western States.

Book Description
"Studies on the Interaction of calcareous liming and phosphate uptake were begun using neutron-bombarded monocalcium phosphate and neutron-bombarded superphosphate. Greensboro loam, a soil type previously studied on the Macdonald College Sawyerville plots (32), was used. The experiment was set up in the greenhouse as a split-plot design with six replicates of prelimed and unlimed Greensboro loam fertilized with the monocalcium phosphate and a similar supplementary trial with the superphosphate. Banner oats were used to measure the uptake of the soil phosphorus and fertilizer phosphorus.[...]" --

Book Description
Phosphorus (P) is a finite resource which is essential for life. It is a limiting nutrient in many ecosystems but also a pollutant which can affect biodiversity in terrestrial ecosystems and change the ecology of water bodies. This book collects the latest information on biological processes in soil P cycling, which to date have remained much less understood than physico-chemical processes. The methods section presents spectroscopic techniques and the characterization of microbial P forms, as well as the use of tracers, molecular approaches and modeling of soil-plant systems. The section on processes deals with mycorrhizal symbioses, microbial P solubilization, soil macrofauna, phosphatase enzymes and rhizosphere processes. On the system level, P cycling is examined for grasslands, arctic and alpine soils, forest plantations, tropical forests, and dryland regions. Further, P management with respect to animal production and cropping, and the interactions between global change and P cycling, are treated.
