Silty Loam Characteristics Drive Workability
The soil is comprised of 60.1% silt, 22.0% sand, and 17.9% clay. This mix provides a balanced texture that offers better drainage than high-clay soils while retaining more nutrients than sandy ones. It is a versatile composition for diverse agricultural uses.
Strong Organic Matter Levels Boost Growth
Holmes County soil contains 2.05% organic matter, surpassing both the state average of 1.81% and the national average of 2.0%. Combined with an available water capacity of 0.198 in/in, this soil provides a nutrient-rich environment for local farmers. The higher organic content helps buffer the soil against rapid pH changes.
