Wagner, South Dakota
These pictures are taken from two neighboring fields.
They were both supposed to have been treated with PRO CAL 40, but due to the wet spring only one got done.
The treated field received 2 ton/acre. There is quite obvious differences in the soil and the crop. The corn in the treated field is much darker green and somewhat larger. This soil has 3-5% sodium and at least 30% magnesium. The consultant on this field commented on how much better the stand was where the PRO CAL 40 is and also much more uniform in size. The soil in the untreated field was much harder and the cracks were more numerous and larger than in the PRO CAL 40 treated area.
