Nudge your soil pH toward what your plants prefer with a workable estimate of how much amendment to spread. Enter the current pH from a soil test, the target pH, your bed area in square feet and the soil texture, and the calculator decides whether you need lime to raise pH or elemental sulfur to lower it. It uses common per thousand square foot rates that increase for heavier clay soils, which resist change, and eases off for sandy soils. The result is a starting amount in pounds, best applied in stages with a retest, since pH shifts slowly over months. Most vegetables thrive between about 6.0 and 7.0. This is a planning guide, not a lab report. Everything is calculated instantly in your browser with no signup.
