This creates a product that has a tremen-dous amount of surface area, and this composition is excellent at holding nutrients, moisture, and beneficial bac-teria, and also supporting fungi such as mycorrhizae,” says Sump. He adds that the ProGanics and Flexterra combination has tremendous water-holding capacity, and “when combined, holds 13 times their weight in water, a valuable asset to help veg-etation establish in this arid climate. When you have low topsoil, low rain-fall, and no organic matter, you need to compensate.” He notes, “With this project we could see clearly how this soil did not hang onto the moisture. Plus, the Cana-dian parks are very strict about what kinds of plantings can be done, and we had to provide certification that veri-fied no foreign weed, unwanted plant material, pathogens, or other undesir-ables would be introduced.” Although it was not required, Profile did perform a soil test to determine the composition of native soil to be able to create a suitable biomass mix. The test showed that the slope soil was high in pH (8.2), and very low in organic WWW.EROSIONCONTROL.COM 16 EROSION CONTROL
