Efficiency of (/sup 32/P) triple superphosphate on four soils derived from volcanic ashes

Journal Article:

Abstract

The efficiency of triple superphosphate on four soils derived from volcanic ashes (Andepts) was evaluated. Experiments in greenhouse with rye grass was carried out. Three doses of superphosphate (150,300 and 600 kg P/sub 2/O/sub 5//ha) labeled with /sup 32/P were used. The fertilizer was located 2.5 cm underneath the seed. The phosphorus derived from the fertilizer represented a 70 percent from the total P absorved by the plant. The utilization of aggregated nutrient ranged from 2.1 to 5.2, the lower values being obtained for the higher rates. Value 'A' increased with the rate applied but it evaluated comparatively the four soils studied. The isotopic method distinguished quantitatively the P coming from the soil in distinction to the P coming from the fertilizer.
