>We have been trained to focus on nitrogen, phosphorus, potassium, and sulfur fertility for the last few decades. With a bit of math and some background knowledge of the field, hopefully a soil test, we can put together a pretty good recommendation. But there are many nutrients that we are beginning to learn play a really big role in crop development, and even the efficiency of how that plant can uptake and use N,P,K and S.
I am not a soil scientist by any means. So I am going to avoid technical jargon because I would probably get it wrong. But if we assume that we have a handle on how much NPKS we need,
and are getting that right, we then move down to the micro nutrients. Zinc, Magnesium, Copper, and many more.
If our limiting factor is a nutrients we need to address it. And sometimes the soil has lots of a nutrient, but it is tied up because of pH. Or it is tied up because of an abundance or lack of another nutrient. Proper soil tests, and someone that can analyze it, are needed to figure this out. Computer generated recommendations are junk.
Omex showed us trial results and pictures from last year, with big differences in the the jump out of the ground. Zinc treatments getting the crop up earlier, and growing faster. Copper helps cereal crops in many aspects. On the left is the untreated (seed treatment and inoculant only), on the right is treated with Omex Pulse Primer (and seed treatment and inoculant)
Yield is always the benefit we are looking for, but sometimes maturity is just as important, or even more valuable. These products did show a yield increase significant enough to justify them. But the maturity, and ability to combine 3 or 4 days, or even weeks sooner in some cases, was the difference between a #1 Lentil worth 38 cents, and #3 worth less than 20 cents. Over $300 per acre benefit on a 25 bushel lentil crop could be realized under certain circumstances.
