Will Your Soil Be Responsive to Gypsum?
(Aldrich and Schoonover, 1951)

Yes if:

(a) soil pH is over about 8.2 and maybe even if it is less

(b) ESP is over 3 and definitely if it is over 9

(c) Water puddles on it

(d) the soil particles slake or disperse when added to water

(e) the subsoil pH is lower than 5, (of) there is waterlogging in the soil

(f) there is crust on the soil after a rain or irrigation

(g) there is excessive cracking of the soil after rain or irrigation

(h) irrigation water contains substantial amounts of bicarbonate (however, be aware of caliche forming in the subsoil)

(i) Intense rain falls on soil that is not acidic and where all solutes may be leached from the soil surface

(j) No-till is used
