Abstract
Abstract The availability and uptake of soil and fertilizer P was studied with dryland spring wheat under four moisture regimes in a field experiment in eastern Montana. The Chestnut soil used was moderately low in available P (6.2 ppm. NaHCO 3 ‐soluble P per acre). Fertilization with P, higher soil moisture supplies at seeding time, and additional precipitation during the growing season, all increased total P uptake by spring wheat at all stages of plant growth. Interactions between any of these three factors seldom affected total P uptake at any stage of growth. Increasing the supply of soil moisture at seeding or growing‐season precipitation increased plant uptake of soil P. However, P fertilization reduced soil P uptake. Moisture supplies at seeding and growing‐season precipitation did not affect uptake of fertilizer P, except at the tillering stage of growth. The percent of total P in plant material derived from fertilizer was generally lowest in treatments receiving the most moisture, either as stored soil moisture or growing‐season precipitation. NaHCO 3 ‐extractable P was not influenced appreciably by moisture conditions.
