Rhyzogreen is a direct food source for the soil microbial population, designed to impact root structure, plant health, and ultimately yield.
Soil health directly correlates to plant health. There is an enormous amount of nutrients in the soil, but only a small percentage is actually in a form that the plant can take up.
Soil microbes convert soil nutrients into a form the plant can absorb and use. But, if a soil's microbial community is stressed by poor growing conditions like soil compaction, excess moisture, or not enough moisture, up to 80% of microbes can remain dormant or inactive!
