We break down what “salty soil” really means and why salinity and sodicity demand different fixes. We share how to properly diagnose a soil as saline, sodic, or saline/sodic through soil sampling and testing, to avoid turning a manageable patch into concrete.
We also discuss....
• defining normal, saline, sodic, saline-sodic with soil test EC and sodium results
• why salinity causes drought-like stress without wrecking structure
• how sodicity drives clay dispersion and pore collapse
• when salts keep clays flocculated in saline-sodic soils
• risks of leaching or tiling without a sodicity management plan
• sampling depths: 0–6, 6–12, 12–18 inches for diagnosis
• using pH as a supporting clue for sodicity
• prioritizing amendment before drainage to prevent sodic blowups
