Abstract
Abstract In a pot experiment with oats as the crop, two levels of soil moisture and two of temperature were used together with five rates of application of superphosphate, on two soils, one high and one low in available phosphorus. An increase of approximately 5°C in soil temperature maintained throughout the growth period considerably increased the uptake of soil phosphorus from both soils. Lowering of soil moisture tension to field capacity greatly increased the uptake of fertiliser‐P from both soils. As found in earlier work, applications of superphosphate to the high‐P soil gave rise to the absorption of large “luxury” amounts of phosphorus with no effect on crop yield.
