Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Grain Sorghum, A. Schlegel, H. D. Bond
Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Grain Sorghum, A. Schlegel, H. D. Bond
Kansas Agricultural Experiment Station Research Reports
This study was initiated in 1961 to determine responses of continuous grain sorghum grown under flood irrigation to N, P, and K fertilization. The study is conducted on a Ulysses silt loam soil with an inherently high K content. The irrigation system was changed from flood to sprinkler in 2001.

Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond
Long-Term Nitrogen And Phosphorus Fertilization Of Irrigated Corn, A. Schlegel, H. D. Bond
Kansas Agricultural Experiment Station Research Reports
This study was initiated in 1961 to determine responses of continuous corn and grain sorghum grown under flood irrigation to N, P, and potassium (K) fertilization. The study is conducted on a Ulysses silt loam soil with an inherently high K content. No yield benefit to corn from K fertilization was observed in 30 years, and soil K levels remained high, so the K treatment was discontinued in 1992 and replaced with a higher P rate.
