spectrometer on his farm in New Zealand in January and finding a Brix of 16 in his mother's plum fruit and only 6-7 in his corn. Too much corn in the United States won't test above 7 and very little tests 10.
Brix is a measure of sugars. When measured in plant sap, it is an indication of overall health, fertility and environmental conditions. This Ohioline Bulletin on vegetables is a good read to get acquainted with brix levels in crops. I had gotten interested in Brix levels in crops some years ago but put it aside as yields increased. The Farm to Plate conference in Iowa in December got me interested after Joan's pronounced Johanne, presentation there. The video is a good review of what attendees heard.
Every sample that has been analyzed are pretty much what I posted. We tend to over nitrate every crop and under feed the other 16 nutrients or elements. C, H, O are the foundation blocks and too many soils are deficient in Carbon and saturated or deficient in H2O most of the time. How can we get the corn to test and respond like the plum I tested?
Every plan we make and every thing we do affects that Brix level which affects plant quality greatly and final yield. Mike noted where he found soybean aphids, the soybeans were too high in nitrate. They are probably low in some other elements, too.
We are pushing Jeff and George to get set up to do the same test in Minnesota. They are so busy with glyphosate right now, I don't think they have the needed time to dedicate to it at this moment. It will come though, knowing those two.
