High Alkali Well Water Poisoning Soil: Fix the Water First

A Reno, NV gardener had high soil alkali from well water, tried various amendments (pyrite, gypsum, charcoal, zinc) with poor results.

Core Problem

Amending soil is futile if irrigation water keeps adding alkali. Fix the water first.

Hire a water filtration company; install whole-house/irrigation treatment.
Retest soil pH after water is corrected.
Consult local independent nurseryman—they know regional alkali-tolerant plants and amendments.

Don't chase soil chemistry while the source persists.
