Fertilizer Requirement of Irrigated Alfalfa

Results of the last 3 years indicate that a combination of soil and tissue tests provide the best option for predicting P response in alfalfa. However, neither worked well for K.

IPNI-1994-CAN-AB11

Surveys have indicated that there is a discrepancy between soil and tissue tests for P and K in many irrigated alfalfa fields in southern Alberta, and that insufficient P and K was being applied to these fields. Results of the last 3 years indicate that a combination of soil and tissue tests provide the best option for predicting P response in alfalfa. However, neither worked well for K. Read more
