Land and Soil
McLennan County Sits on Two Distinct Prairie Zones
The county spans both the Grand Prairie to the west and the Blackland Prairie to the east, giving it fertile soils suited to row crops, hay, and cattle.
The Blackland Prairie in eastern McLennan County has some of the richest clay soils in Texas. Cotton dominated agriculture here from the 1880s through the mid-20th century. Today the county produces beef cattle, corn, wheat, hay, grain sorghum, soybeans, and dairy cattle.
Blackland clay soils can shrink and swell dramatically with rainfall changes. This affects building foundations and is worth knowing before buying or building on this type of land. If you have specific ag questions, Texas A&M AgriLife Extension has a McLennan County office.
