secondary salinization

Secondary salinization occurs when salts accumulate in soil or water, primarily due to irrigation practices in arid regions. Irrigation water contains dissolved salts, which become more concentrated as water evaporates from the soil. This residual salt builds up, harming plant growth by causing dehydration and hindering nutrient uptake.12

A drainage problem is intrinsically linked to this process. Effective drainage is crucial for removing excess salts from irrigated lands through leaching. Without adequate drainage, salts accumulate, rendering the land unproductive and potentially contaminating freshwater sources through saltwater intrusion. This accumulation of salt can also damage infrastructure and pose health risks if consumed.324
