Recent Study by ARS Researchers Suggest That Switchgrass May be Better for Your Soil
This article takes an interesting look at an ARA study relating the amount of glomalin, a sugar-protein, in switchgrass to the potential erodibility of soils. The more glomalin a soil contains, the less likely that soil is to erode. The study found that as plants formed a symbiotic relationship with fungi in the soil, glomalin levels rose. This increase was most pronounced under native warm season grasses like switchgrass. Glomalin also stores carbon and adds to soil fertility. The article also links to the ARS study.
