Salt kills germinating seedlings by removing the water from their cells (plasmolysis, exomosis). Several salts and their ions are responsible: NaCl, CaCl, KCl, MgCl, MgSO4, HCO3 -- CO3 -- MgCO3, NO3-, NH4+, K+.
How does agriculture lead to salinization of soil? Irrigation of water with dissolved salts (from a lake or other source) puts salts on the land. When plants use the water, salts are left behind, becoming more and more concentrated over time.
Soil Salinization is an important lab in AP Environmental Science. Learn how to set up and help your students have a successful soil salinization lab.
Irrigation water contains a variety of dissolved salts including NaCl, MgCl2, Cacl2 , etc. When a field is irrigated, much of the water can evaporate, leaving these salts behind as a thin layer on top. Over time, salts build up on fields until the soil is so salty (salinized) that seeds will no longer germinate in the soil.
Study with Quizlet and memorize flashcards containing terms like Salinization, What causes salinization?, How to remediate salinization and more.
Soil salinization is a term that indicates the phenomenon or process of accumulation of water-soluble salt in the soil. Based on the drivers and mechanisms, it can be summarized in two subcategories: primary salinization, and secondary salinization (Li et al., 2014).
