Build-A-Soil has done thousands of soil tests and over the years and we've noticed that our particular soils are usually very high in Iron but very low in manganese and 5 other Micro-nutrients like Boron, Cobalt, Copper, Molybdenum and Zinc!

Once you regain balance in your Iron to Manganese relationship and bypass the limiting factors of the others, you are in a position to drastically increase yield and disease resistance.

These 6 Micronutrients are balanced and chelated through Faust Ful-Humix Humic Acid to make sure that we can use safe amounts and they will only help the plants
