About Soil in Sharkey County, Mississippi
Superior Soil Quality in Sharkey
Sharkey County boasts a soil score of 53.7, the highest in this group and well above the state average of 35.7. The average pH of 6.24 is the closest to the national median of 6.5, making it significantly less acidic than the 5.30 Mississippi average. This unique profile makes it some of the most productive agricultural land in the state.
Rich Clay and Silt of the Delta
With a high clay content of 35.8% and 48.5% silt, Sharkey soils are heavy and nutrient-dense. Sand only accounts for 15.7% of the soil, meaning these fields hold onto water and fertilizers exceptionally well. These are the famous 'buckshot' soils that define the Mississippi Delta's agricultural power.
Excellent Moisture Retention for Crops
Sharkey County’s available water capacity is 0.183 in/in, surpassing the state average of 0.174 in/in. Although organic matter is 1.64%, which is slightly lower than the state's 1.81%, the high clay content provides an incredible reservoir for plant nutrients. This soil is naturally equipped to sustain high-yield agriculture with minimal amendment.
Managing the Delta's Heavy Clay
The 35.8% clay content suggests that while the soil is fertile, drainage can be slow and problematic during wet seasons. These soils expand when wet and contract when dry, requiring careful management of heavy machinery. However, the high silt and clay levels ensure that once water is absorbed, it stays available for the crops.
Abundant Growth in Zone 8b
Located in hardiness zone 8b, Sharkey County is an agricultural powerhouse perfect for cotton, soybeans, and corn. Home gardeners will find that the near-neutral pH allows for a vast range of vegetables without needing much lime. If you have access to this Delta soil, you have some of the best gardening potential in the country.
