Should You Use Micronutrients or BioStimulants

A recent article in Prairie Farmer explores the use of micro-nutrients and bio-stimulants.  Karen Corrigan is quoted extensively and she is a very respected agronomist.  Karen says to use both soil testing and tissue sampling to determine needs.  I find myself in agreement with her concerning many of the additive mixes.  Often the amount of nutrient in the mixes will not completely correct a real problem area.

I also learned from Ted Peck that correcting the macro-nutrients and soil pH soil be done first.  If P, K, Ca, and Mg are not correct, there is no use messing around with the micros.  I always try to correct the big things first.  After a year or two we can look at micro's when everything else is right.  If you macro-nutrients are all at or above ideal levels, then perhaps you can push yields with micro-nutrients.

Bio-stimulants are coming into their own with many of the bigger ag supply companies owning or researching products.  Some of the products that are used for seed treatments have become mainstream.  Others need to be tested on your farm as Ms. Corrigan points out.
