Healthier soil. Bigger roots. More profit per acre.
Pro-Soil's natural, biological products wake up the microbial life already in your ground, freeing tied-up nutrients so every fertilizer dollar works harder.

Mellow, living soil
Nutrient deficiency isn't fertilizer deficiency.
Years of the same tillage, chemicals and fertilizer have left a lot of ground biologically worn out, with nutrients locked up where roots can't reach them. Adding more fertilizer rarely fixes it.
Everything you put on your field has to go through a biological process to work. Pro-Soil feeds and stimulates that native microbial life, so the nutrients already in your soil (and the ones you pay for) actually reach the plant.
How Below Ground Management worksFeed the soil. The soil feeds the crop.
Every Pro-Soil product is built on a proprietary poly co-ferment enzyme concentrate, plus vitamins, organic acids, chelated trace minerals, humates and kelp.
Improve soil energy
A more active, higher microbial population turns organic matter into usable humus.
Increase root mass
Bigger root systems reach further for moisture and nutrients.
Free up reserve nutrients
Release nitrogen and other nutrients tied up in the soil.
Boost fertilizer efficiency
Get more from every application and gradually reduce inputs.
Break down residue
Faster residue decomposition recycles energy back into the field.
Raise yield potential
Mellower soils, better plant health and stronger stands at harvest.
Below ground. Above ground.

Over the last five years we have found this product to enhance yields probably more than anything we've done in the last 40.
Input prices keep rising and your program allowed me, after 3 years, to cut back on fertilizer 50%, and on some fields a 60% reduction with herbicides!
The first two years on the Pro-Soil products we saw a 12 to 13 bushel improvement on side-by-side comparisons for our wheat crop. Best product we've found!
