PotashCorp: Ear leaf tissue test reveals what a soil test can’t

Coupling tissue testing with soil testing can help yield big returns at a relatively small cost.

Check out this video from PotashCorp where Dr. Robert Miller, Colorado State University discusses how tissue testing can help growers assess and optimize their soil fertility programs.
