Below the surface
Healthy turf starts with roots and the soil biology that feeds them.
Why biological fertility
Feed the soil, and the soil feeds the turf
Conventional programs push top growth and leave soil depleted. Each Sigma granule combines slow-release organic nutrients, humic acids and live beneficial organisms. Together they cycle nutrients, improve soil structure and grow the deep roots that carry turf through drought, heat and heavy traffic.
- Beneficial Bacillus bacteria
- Attach to roots and help plants take up nitrogen, phosphorus and potassium, while crowding out harmful bacteria.
- Mycorrhizal fungi
- Colonize the root zone while connecting plants under the surface, reduce soil pathogens and promote vigorous, healthy growth.
- Trichoderma fungi
- Extend the root system's reach several hundredfold through fine fungal filaments, improving access to water and nutrients.
- Humic acids & organic carbon
- Hold nutrients and moisture in the root zone and feed the soil's microbial life.
