Does Gypsum Break up Clay?

Clay soils in commercial agricultural sites are often treated with gypsum to help break up the clay and enhance calcium, which breaks up excess sodium. The effects are short lived but serve to soften the soil enough for plowing and sowing.

How long does gypsum take to break up clay?

Clay can be a sticky mess, poorly drained and set like concrete. The traditional way to treat a large area of soil is powdered gypsum, which we sprinkle over and then dig it in. But it does take a long time to dissolve and it'll be a couple of months before you get the full effects.

Will gypsum break down clay?

The main reason for applying gypsum is to loosen and break up clay particles in the soil. It does not work instantly but has to be re-applied on a yearly basis for best results. Simply apply to the soil surface and water in thoroughly afterwards.
