SGTX promotes the use of Fungi-to-Bacteria ratios as a key to understanding how a below-ground soil foodweb succession parallels an above-ground plant ecological succession. The following chart illustrates this concept. Early-successional plants (invasive weeds and annual crops) are bacterial-dominated while late-successional plants (prairies, trees, and forests) are fungal-dominated. The numbers in the chart are based on soil biology lab tests. They are reported as Total Fungal Biomass : Total Bacteria Biomass (F:B) in micrograms per gram.
The soil biology test provides a practical glimpse of which kinds and how many soil critters make up the existing soil foodweb on a farm, ranch, yard, park, etc. This chart guides SGTX work. We use liquid biological amendments as a tool for managing soil biology. Bioaugmentation (adding biology) and biostimulation (feeding and stimulating soil biology) practices are employed to encourage an active soil foodweb that more closely matches the crop’s needs in terms of a bacterial-dominated or fungal-dominated soil ecology.
In Texas, this approach has been successful in pastures, prairies, pecan orchards, erosion control projects, and urban lawns and landscapes. We rely on liquid biological amendments, microbial foods, trace elements, and selected microbial strains to build healthy soils and grow healthy crops.
