Are You Keeping Up With Sulfur in Your Fertility Program?

  In visiting with producers about their soil tests and soil fertility, I often have noticed that they haven’t tested for sulfur.

What amount of heavy metals am I allowed to apply to my fields?

This means timely operations and especially more timely planting.  Since we have applied gypsum on all our fields we don’t normally have […]

Solutions to Increasing Soybean Yields

Researcher was Gueillermo Balboa et al.  (Kansas State University) and the second article was in Corn and Soybean Digest “Understanding 120-bushel soybeans”….Researcher was Sotirios Archontoulis (Iowa […]


In the fast paced world we live in today it is easy to forget to say thank you.  We don’t want to forget to say thanks to our PRO CAL 40 and NutraBio customers that had these products applied this past fall, winter or spring.  Soil Solutions feels very fortunate to have had a busy […]
