Bio S.I.TM Ag Formula + Humus Soil Inoculant

Bio S.I. AG Formula + Humus Soil Inoculant is a soil inoculant with a broad and diverse spectrum of naturally occurring beneficial microbes and enzymes for rebuilding the soil. Can be used on row crops, broadcast crops, pastures, grass, vineyards, orchards, fruits and vegetables of all types to help rebuild the soil. Bio-S.I Agriculture products help reduce crusting and break down organic matter (plant residue) into humus. Humus is the fraction of the soil that holds water and nutrients in the rhizosphere (root zone). Microbes also help make nutrients more available for use by the crop by breaking down the fertilizer or nutrients so they can be absorbed through the roots.

We know the most important thing to you is crop production, grade and marketability of your crop at the highest possible price. When we see chemical cost going higher and higher we need to make whatever we use more efficient and using Bio S.I. Ag Formula + Humus Soil Inoculant improves the efficiency of your fertilizer program and reduces the environmental impact of chemical use.
