WebJan 20, 2024 · The HWSD distinguishes soil characteristics for topsoils (0–30 cm) and subsoils (30–100 cm). Since our investigation focuses mainly on the salt accumulation close to the soil surface, the extent of soil salinity in this study was solely based on the HWSD saline mapping unit for the topsoil (0–30 cm). WebSalinisation (the accumulation of salts in soil)is one of today’s worst environmental disasters and yet it does not share the global spotlight with other ecological issues. …

Weband the use of low quality water can lead to the accumulation of salts in the soil, since the leaching fraction is reduced and the salts contained in the irrigation water are not leached enough. It is estimated that, by 2050, 50% of the world’s arable land will be affected by salinity [5]. Soil salinity reduces the WebSalt-affected soil may contain too much salt, too much sodium, moreor both. An accumulation of gatedsalt in the soil may ilarretard plant growth. When sodium, sivewhich is contained in common andsalts, is adsorbed on (adheres to) soil particles, the soil may be difficult to till, and water may be poor. problems are especially se-rious in 17 ...
