Data Story

About Soil in Forrest County, Mississippi

Highly Acidic Southern Soils

Forrest County features very acidic soil with an average pH of 4.62, much lower than the national median of 6.5. This level is also significantly below the state average of 5.30, requiring lime for most traditional gardening.

Sandy Texture and Easy Workability

The soil consists of 50.3% sand and 31.8% silt, making it light and easy to till. With clay at only 9.2%, the ground drains quickly but may struggle to hold onto essential plant nutrients.

Rich Organic Matter Content

At 2.54%, organic matter content is remarkably high, exceeding both state and national averages. Despite this richness, the available water capacity of 0.150 in/in is lower than the state average, meaning irrigation is often necessary.

Rapid Drainage Characteristics

While specific drainage class data is limited for this area, the high sand percentage ensures fast water movement. This physical makeup helps prevent root rot but requires careful management of water resources during dry spells.

Blueberries Love Zone 8b

The warm Zone 8b climate and acidic soil create perfect conditions for blueberries and azaleas. Local growers should focus on acid-loving plants to take full advantage of the county's natural soil chemistry.

Soil & Planting Advisory: Forrest County

Soil Verdict

Forrest County is in USDA hardiness zone 8b, a warm climate zone. where winter lows can reach 15°F. Mild winters mean soil rarely freezes deeply, allowing year-round microbial activity and faster organic matter breakdown.

Planting Guidance

Warm-season crops, citrus relatives, and heat-loving ornamentals do well. Cool-season vegetables should be planted in fall and winter. Always match plant selections to the specific microclimate of your property — low spots, slopes, and wind exposure can shift effective hardiness by half a zone.

Soil Implications

Warm soils accelerate organic matter breakdown, so compost and mulch need replenishing more frequently than in cooler zones. Sandy soils common in warm zones drain quickly; water-retentive amendments like compost or peat help hold moisture.

Regional Context

Forrest County closely matches the Mississippi average hardiness conditions.
