Abstract: Agriculture has failed to be sustainable several times in the history of the world because of soil failure (Rush, 1987). Irrigated land eventually leads to sodicity and salinity unless extreme care is taken. Gypsum is a key ingredient for the maintenance of agriculture on many types of soils and over a wide pH range including sodicity. Waste …

Powdered gypsum is used to increase the pH in mushroom growing substrates such as coco choir, sawdust, coffee grounds and straw. It is a yield enhancer as it supplies minerals and trace elements to the …
Shurtleff recommends 2 tsp of gypsum for 7 1/2 to 8 cups of soy milk. Nguyen recommends 1 1/2 tsp for 8 cups of soy milk. (These recipes are for about 1/2 gallon of soy milk. There are 16 cups in a gallon) I can't verify with personal experience, as I use Epsom salts (magnesium sulfate) as a coagulent, but have had success with both …
Gypsum is non-toxic and safe for people and pests. It works well for yard vegetables, and flower gardens, and around trees, and shrubs. It is sold commercially in a granular powder or pellet for use in the home garden for large-scale agriculture. Gypsum is used for soil conditioning and fertilizing.
1 teaspoon of gypsum powder weighs about 3.4 g. Gypsum powder helps establish a more basic pH of the grain spawn and helps prevent grains from sticking to each other. 4. Let the grains soak for 12-24 hours. Soaking allows the shell of the grain to soften and absorb more water later, when boiling.
