MOP- Potassium chloride is occasionally known as "muriate of potash," particularly when used as a fertilizer. t's odd how this old-fashioned name remains in use! Muriate comes from Muria, the Latin for brine. Muriate of potash is potassium chloride containing between 50 and 60 per cent potash. It was deposited eons ago by ancient seas and should be considered a natural product, blessed by organocultists, but it is not. Its chlorine content passes off rapidly when applied to soil.

As explained under soil organisms, however, muriate of potash is harmful to certain beneficial bacteria. Some authorities think sulfate of potash makes a better potash fertilizer.

SOP - Sulfate of Potash

This contains 48 per cent potash. It is more expensive than muriate of potash but is considered less harmful to bacteria and plant roots.Sulphate of Potash is virtually chloride free with a salt index of only 46 (whereas Muriate of Potash is 114). The essential sulphur content is in the readily plant available sulphate form. Sulphate of Potash consists of grey or white granules.?
Providing potassium to crops sensitive to chloride and salt

Contains a low salt index helping to avoid the plant taking up excess water

Mixes well with all other fertiliser.

Depending upon your soil ph , you can decide if you want to use SOP or MOP.

Rock Salt/Halite:

halite  (NaCl)

Halite is often used both residentially and municipally for managing ice. Because brine (a solution of water and salt) has a lower freezing point than pure water, putting salt or saltwater on ice that is near 0 °C (32 °F) will cause it to melt. (This effect is called freezing-point depression.) It is common for homeowners in cold climates to spread salt on their walkways and driveways after a snow storm to melt the ice. It is not necessary to use so much salt that the ice is completely melted; rather, a small amount of salt will weaken the ice so that it can be easily removed by other means. Also, many cities will spread a mixture of sand and salt on roads during and after a snowstorm to improve traction.
Salt is also used extensively in cooking as a flavor enhancer and to cure a wide variety of foods such as bacon and fish.[4] Larger pieces can be ground in a salt mill or dusted over food from a shaker as finishing salt.

Gypsum:

Gypsum is used in a wide variety of applications:
Gypsum board[16] is primarily used as a finish for walls and ceilings, and is known in construction as drywall, sheetrock or plasterboard.
Plaster ingredient (surgical splints, casting moulds, modeling)
Fertilizer and soil conditioner: In the late 18th and early 19th centuries, Nova Scotia gypsum, often referred to as plaster, was a highly sought fertilizer for wheat fields in the United States. It is also used in ameliorating high sodium soils.[17]
A binder in fast-dry tennis court clay
As alabaster, a material for sculpture, especially in the ancient world before steel was developed, when its relative softness made it much easier to carve than stone with available tools.
A wood substitute in the ancient world: For example, when wood became scarce due to deforestation on Bronze Age Crete, gypsum was employed in building construction at locations where wood was previously used.[18]
A tofu (soy bean curd) coagulant, making it ultimately a major source of dietary calcium, especially in Asian cultures which traditionally use few dairy products
Adding hardness to water used for homebrewing[19]
Used in baking as a dough conditioner, reducing stickiness, and as a baked-goods source of dietary calcium.[20] The primary component of mineral yeast food.[21]
A component of Portland cement used to prevent flash setting of concrete
Soil/water potential monitoring (soil moisture tension)
A common ingredient in making mead
In the medieval period, it was mixed, by scribes and illuminators, with lead carbonate (powdered white lead) to make gesso, which was applied to illuminated letters and gilded with gold in illuminated manuscripts.
In foot creams, shampoos and many other hair products
A medicinal agent in traditional Chinese medicine called shi gao
Impression plasters in dentistry
Used in mushroom cultivation to stop grains from clumping together
