The northern part of the county has sandy and light loamy soils over deep reddish or mottled, clayey subsoils. In some areas limestone lies within forty inches of the surface. The southern part of the county has moderately deep to deep loamy surfaces over clayey subsoils. Along the Rio Grande brown to red clays occur. Hidalgo County is in the South Texas Plains vegetation area, which features grasses, mesquite, live oaks, and chaparral.

The primary fruits and nuts grown in the county were grapefruit, oranges, and pecans. Cattle, milk cows, and hogs were the primary livestock products. Natural resources included caliche, sand, gravel, oil, and gas. Oil and gas production in 1982 totaled 98,487,211,000 cubic feet (2.7888472×109 m3) of gas-well gas, 139,995 barrels of crude oil, 1,101,666 barrels of condensate, and 15,784,000 cubic feet (447,000 m3) of casinghead gas.
