How mixed the soil is

Of the 297,539 surveyed acres in Real, TX, 59% are alkaline (above 7.3), 40% are near neutral (6.5-7.3). Mapped soils run from pH 6.2 to 8.2, a spread of 2 units across 45 soil components. No single class covers 60% of the county, so two gardens a few miles apart here can need opposite treatments. Test your own bed.

Clay, organic matter and rates

Topsoil here averages 38% clay and 5.67% organic matter, which this site treats as clay. At 5.67% organic matter the soil buffers like a heavier one, which pushes it into the clay bracket.
