17.5 Cracking The Code Of Salty Soils

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 blowupsMore information on management of salty soils here: https://www.ndsu.edu/agriculture/extension/publications/managing-saline-soils-north-dakotaTune in next time for a Tiny Byte of knowledge from GK Technology, where we have a map and an app for that.https://gktechinc.com/
