9552. Bonczkowski, L.C., R.E. Lamond and D.A. Whitney. 1988. Effects of chloride rates and sources on winter wheat in Kansas.. Kansas Fertilizer Research p. 7-12.
For wheat and some other cereal grains, chloride has been reported to have an effect on plant diseases, either suppressing the disease organism or causing the plant to be able to withstand infection. It is hypothesized that yield increases are due to these effects. Researchers from several states have been able to show yield increases from chloride-containing fertilizers. The most common source is potassium chloride. In many cases, soil test potassium levels are high, and most soil test recommendations call for no additional K; however, when small increments of KCl are used, some yield increases have been reported.
9642. Havlin, J.L., A. Radhouani, A.J. Schlegel and J. Zupancic. 1988. Phosphorus fertilization for dryland wheat in western Kansas.. Kansas Fertilizer Research p. 21-26.
Field research was initiated to evaluate the influence of phosphorus rate and placement on winter wheat production in western Kansas. The primary objectives were to (1) calibrate commonly used phosphorus soil tests; (2) evaluate P rate x placement interaction; (3) establish the optimum soil sampling depth for phosphorus; and (4) evaluate the influence of soil sampling method or scheme on soil test P and fertilizer P recommendations on fields where P has been band applied.
