are there rhizospheric soil of grasses in america

Yes, grasses native and cultivated in American ecosystems—including prairie grasses, turfgrasses, and agricultural species—develop rhizospheric soil. This soil is rich in microbial activity due to dense fibrous root systems that exude a wide array of organic compounds. In native prairies, rhizospheric soils contribute to carbon sequestration and soil structure stability, while in agriculture, they influence nutrient dynamics and crop performance. Regional differences in soil type, climate, and plant genotype affect rhizospheric properties.
