Pretty hopeless in predicting deficiency

There’s an interesting blog post by Jim Orson titled “Read this before leaf tissue testing for micronutrients.”

The entire post is worth reading. It describes his conclusions after studying the result of 15 trials with winter wheat.

“That’s not turfgrass,” you might say. And rightly so. But I couldn’t help but notice that there are striking similarities between these results with wheat and the four reasons I don’t recommend leaf nutrient analysis to choose which fertilizers to apply to turfgrass.
