Short excerpt from a YouTube video by John Kempf describing an on-farm observation: in a 160-acre field (40-acre block) where corn seed was inoculated with BioCoat Gold, treated corn yielded a 16.9 bushel/acre increase compared with untreated areas. The field had previously grown horseradish (a brassica with a two-year cycle), and the speaker suggests the yield response may be due to restoring mycorrhizal colonization after a long, heavily-tilled brassica-dominated period.

One particular circumstance I can highlight is 160 acre field that had a 40 acre block where we saw a 17 bushel response as a result of inoculating corn seed with biocold gold. That was really quite stunning. Now a little bit more nuance on why that response was so significant. This was on corn following horseradish. And the astute observer will recognize that brassicas don't colonize mycorrhiza. So if you follow supposedly. Sure, there's caveats there. I understand that. Generally speaking though, if the. If the degree of colonization in Nebraska, like horseradish, isn't as robust as other types of grasses or legumes, then the assumption is coming back in with a mycorrhizal inoculant in an environment that had been heavily tilled, that had a primarily brassica for not just a growing season, but actually 18 months. Because horseradish is a two year crop growing cycle. The assumption is that perhaps there would be a positive response by putting mycorrhize in the system and then, you know, taking that to yield. We did see a 16.9 bus response where the corn that was treated with biocoat gold certainly stepped above the non treated areas of the field.
