WebMay 1, 2013 · Highlights Soil salinity is an important evolutionary stress factor even for non-halophytes. Results from Australia, support a role for salinity in evolutionary ecology of Acacia. On a contemporary time scale, soil salinity plays a role in weed invasion in Australia. Ecological models need predictors to represent the drivers of distribution. … WebSoil Salinization Definition. All soils contain salts, but an excess salt concentration can disrupt ionic balances in soil and can have cascading negative effects on plant nutrient … WebSoil salinity in agriculture in a simpler and most correct definition is the high concentrations of salts in the soil profile. The process of salinization can occur either naturally or by anthropogenic activities. The high concentration of salts interrupts the plant’s metabolism making them unable to absorb water, nutrients, and microelements. fortnite item shop january 20 2022
