Relationship of Soil Temperature, Water Soluble Phosporus in Applied Fertilizer, and Method of Placement to Growth of Winter Wheat1
- 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.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
