Texas's land-grant extension doesn't use a one-size-fits-all number — it uses a published method. Enter your soil-test values in the free calculator and Zone Forge returns tons of CaCO₃-equivalent per acre, ECCE-adjusted, with the citation.
MOST OF TEXAS does not need lime. Acidic exceptions: East Texas Piney Woods, parts of Blackland Prairie, intensively-fertilized South Texas.

It depends on your soil's buffer/acidity reading and your target pH — Texas publishes a method, not a single number. Enter your values in the free Zone Forge lime calculator for tons of CaCO3-equivalent per acre, with the citation.

Zone Forge computes every Texas recommendation from that state's own published land-grant method — lime, soil-test fertilizer, and full variable-rate prescriptions. See the science →
