Soil is the foundation that builds strong crops, plants, roots, turf.

Soil needs carbon... carbon feeds microbes and aids nutrients
to immobilize freely to the roots.

Microbes help breakdown material in the soil...
This break down (Humification) results in the formation of Humus.
Microbes must be present.

Humus holds nutrients until the roots need them.

Humus hold up to 95% of the Nitrogen, 60% of the phosphorus
and 98% of the Sulfur.

Humus also holds moisture and Air Vital for root growth.

During the warm season when microbes are active they encourage the humus
to release more nutrients, just when the roots need them most.

Break this cycle and you will need more fertilizer to get the same yields.
