Abstract

P32 was injected into the soil at specific locations to allow determination of the phosphorus uptake pattern of Phaseolus vulgaris (snap bean), Amaranthus retroflexus (pigweed), and Setaria viridis (green foxtail). All species absorbed phosphorus primarily from the top 6 inches of soil. Bean absorbed phosphorus from a zone of relatively small volume. Pigweed roots showed the greatest amount of lateral spread and foxtail roots the deepest soil penetration.

One, two, three, or four plants of each of the above-mentioned species were grown 6 inches from a test bean plant to evaluate the effects of associated plants on the phosphorus uptake of the test bean. The effects observed were quite different for the three species studied.
