Quantification of Gypsum in Soils: Methodological Proposal

open access: yesSpanish Journal of Soil Science, 2022
Gypsum is widely found in soils under arid and semi-arid climates due to its semi-soluble nature. In spite of that, they are less known than other soils, and this has generated some misunderstandings in some initial pedological concepts and in soil ...
