Project Details:

1. To increase the yield and profit and to improve fertility effectiveness for forage alfalfa on irrigated soils and by this to increase the feasibility of growing alfalfa.
2. To determine if fields which test low in soil phosphorus and adequate in tissue phosphorus respond to phosphorus fertilizer applied with various methods.
3. To determine if sols which test adequate in soil potassium and deficient in tissue potassium respond to potassium fertilizer.
4. To compare the Miller, Axley, Kelowna, U. of Sask. Kelowna, Norwest Kelowna, membrane strip and Olsen methods of soil analysis for predicting the phosphate response of alfalfa on high pH irrigated soils.
5. To enlarge the data base for a DRIS tissue analysis model for alfalfa and evaluate the feasibility of DRIS for alfalfa.
