Today gypsum is sold either as ag-gyp or pelletized gypsum. Pelletized gypsum (calcium sulfate) can be easily blended with today’s dry fertilizer materials including urea, ammonium sulfate, diammonium phosphate (DAP) or monoammonium phosphate (MAP).
Q. Does silt or clay hold more water?
Soils with smaller particles (silt and clay) have a larger surface area than those with larger sand particles, and a large surface area allows a soil to hold more water. In other words, a soil with a high percentage of silt and clay particles, which describes fine soil, has a higher water-holding capacity.

Q. How do you break up soil without a tiller?
Dig a trench in your garden 12 inches deep. Place all this soil into a wheelbarrow or on a nearby tarp. Dig down another 12 inches, using a garden fork if needed to loosen the soil. Turn over this second 12 inches.
Q. What plants help break up clay soil?
Often plants with taproots will grow well in clay and their roots help break up tough clay soils. Butterfly milkweed, bluestars, and Silphiums have deep tap roots that penetrate clay and that make the plants drought tolerant. Bluestars bloom in spring and have great fall color.
Q. Is clay soil acid or alkaline?
Neutral with pH of exactly 7, for example some clay soils.
Q. How much gypsum do I add to a gallon of soil?
If the soil pH is adequate, apply gypsum (calcium sulfate) at a rate of 1-2 pounds per 100 square foot of soil area, or spray the plant with a calcium solution at a rate of 4 pounds of calcium nitrate or calcium chloride per 100 gallon of water (or 4 level tablespoons per gallon of water).
Q. How much gypsum do I add to grain?
Powdered gypsum is used to increase the pH in mushroom growing substrates such as grain, sawdust, coffee grounds and straw. It is also a yield enhancer as it supplies minerals and trace elements to the mycelium. Gypsum should be mixed at a rate of 2-5% of the dry weight of the substrate.
