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.

This shovel of soil shows the poor soil structure in this soil that has not been treated with PRO CAL 40. It has very little pore space and is hard. Roots had a very difficult time growing through this soil even though it was moist.

This picture was taken from the PRO CAL 40 treated soil in this field. Notice the absence of cracks like those observed in the pictures from the untreated area. The soil surface was also soft and friable.

Notice the better soil structure in this picture of soil shoveled from the treated soil. You may also notice that there is very little soil at the surface that is dry. This is unlike the untreated area that had almost 2 inches of dry crust.

This is another picture of the soil from the treated area. If you look closely you can observe some of the PRO CAL 40 in the soil. It has moved down and is distributed through the top four or five inches. The soil has a nice granular structure.
