Relationship of Soil Temperature, Water Soluble Phosporus in Applied Fertilizer, and Method of Placement to Growth of Winter Wheat1

  1. Joe R. Gingrich2



Top growth total yield of P, and percentage of K in the tops were significantly lower while percentages of P and N were significantly higher in plants grown at 50° F. than in those grown at 60 or 70°. Applying phosphatic fertilizer in a zone, as compared to mixing it with the soil, increased top growth, P percentage in the tops, and total yield of P while it decreased the percentage of K in the tops. In general the amount of dry matter, percentage of P in tops, and total yield of P were increased as the percentage of water soluble P in the applied fertilizer was increased.
