More substantial however is the leaching of the contents of phosphogypsum into the water table and consequently soil, exacerbated by the fact that PG is often transported as a slurry. [3] Accumulation of water inside of gypstacks can lead to weakening of the stack structure, a cause of several alarms in the United States. [6]
The best way to determine if the soil is acidic or deficient in calcium or magnesium is with a soil test which a university can provide with an agricultural education department for under $30.00 for United States residents. [8] Farmers typically become interested in soil testing when they notice a decrease in crop response to applied fertilizer.
The mix is prepared on site using a specialized truck. The truck contains a tank for water, a mixing tank, a holding tank, a pump, and a conveyor for the sand and calcined gypsum. A hopper for the sand and gypsum is mounted externally on the vehicle. [8] To prepare the mix, the sand and calcined gypsum are added to the hopper and mixed.
In soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. [1] There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse ...
A soap substitute is a natural or synthetic cleaning product used in place of soap or other detergents, typically to reduce environmental impact or health harms or provide other benefits.

A gypsum block is made of gypsum plaster and water. The manufacturing process [1] is automated at production plants where raw gypsum (CaSO 4 ·2H 2 O) is ground and dried, then heated to remove three-quarters of the bound water and thus transformed into calcium sulfate hemihydrate (CaSO 4 ·½H 2 O), also known as gypsum plaster, stucco, calcined gypsum or plaster of Paris.
Highly maintained areas of grass, such as those on an athletic field or on golf greens and tees, can be grown in native soil or sand-based systems. There are advantages and disadvantages to both that need to be considered before deciding what type of soil to grow turf in. [4] Native soils offer many positive qualities, such as high nutrient holding capacity, water holding capacity, and sure ...
