Justification
- Foliar application of MKP can enhance phosphorus nutrition of wheat, reduce disease i horticultural crops and enhance the stress tolerance of wheat. Most soils in the Prairie region of Canada are P-deficient for crop production and require P fertilization for optimum yields of crops. However, the efficiency of P uptake from soil-applied P fertilizer may be poor during periods when the topsoil is cold or dry and diffusion of P is limited. Preliminary strip trials show that Foliar Pride applications may alleviate part of this nutritional problem. Disease and stress tolerance is a significant concern for crop production in this area, especially for canola during the flowering and seed formation stages. In preliminary trials with field beans, for example, foliar MKP application in this region have shown positive yield responses, perhaps due to a combination of all three mechanisms previously mentioned for enhanced growth responses.
