www.nrcs.usda.govSoil salinity can affect plant growth both physically (osmotic effect) and chemically (nutritient and/or toxicity effect). As the salt content of the soil increases, it becomes more difficult for plants to take up water. Sensitive plants appear drought-stricken even at fairly low levels of salt concentration. There is usually a
