Phosphorus availability in biosolids-amended soils

Creator:: Choate, Jeff
Abstract:: Quantifying labile phosphorus (P) pools in biosolids is needed to manage biosolids for both agronomic and environmental purposes. Phosphorus indices originated in an effort to protect surface water quality from-non-point-agricultural P inputs. The objectives of this research were to: (1) evaluate soil test components of the western Oregon P index...

Phosphorus characterization in Sri Lankan Alfisols : Soprition, fractions, plant availability and soil test suitablitiy

Creator:: Sattell, Robert R.
Abstract:: Twelve Sri Lankan Alfisols were characterized for P. Soils were incubated for three weeks with sufficient P applied (P2) to elevate soil solution P to 0.2 ug P/g solution as determined by sorption curves, with 75 percent of P2 (P1), and without P (P0). For PO treatments, (a) organic P,...

Availability of phosphorus in central Oregon soils in comparison with selected Oregon soils

Creator:: Araos, Jose Fernando
Abstract:: The objectives of this study were to evaluate and compare the availability of native and applied P in Central Oregon pumice soils with that in Willamette valley soils and calcareous soils from Eastern Oregon. The experimental work to meet these objectives included laboratory and greenhouse studies. The removal of P...

Zinc-phosphorus relationships in five plant species

Creator:: Henning, Stanley John
Abstract:: The effects of zinc and phosphorus treatments on five different plant species were investigated in a greenhouse experiment. A second greenhouse experiment extended these investigations in sweet corn over a broad range of phosphorus treatments with and without adequate zinc nutrition to study phosphorus induced zinc deficiency. The plant responses...

The relationships between zinc, iron, and phosphorus in sweet corn

Creator:: Hay, James Ronald
Abstract:: The relationships between zinc, iron, and phosphorus in sweet corn were investigated under field and greenhouse conditions. The soils used in this study (both acid and calcareous) were low in available zinc and phosphorus. The experiments received standard, uniform rates of nitrogen potassium, magnesium, and sulphur. Corn was used as...
