Plaster is extensively used in the construction industry for interior finishing and decorative purposes. It is commonly applied as a smooth coating on walls and ceilings to create a finished surface. Plaster is also used for creating ornamental elements, such as cornices, moldings, and ceiling roses. Gypsum plaster, in particular, is used for making plasterboard (drywall) panels, which are widely used for interior partition walls. Plaster has significant applications in the medical and dental fields. Plaster of Paris, a type of gypsum plaster, is used for making casts, splints, and bandages. It is commonly used to immobilize broken bones or create molds for prosthetic limbs. Dental professionals also use plaster for creating dental models and molds.

Plaster has agricultural applications, primarily in soil and crop management. Agricultural gypsum, which is a type of gypsum plaster, is utilized to improve soil structure and fertility. It is often applied to soils with high Clay content to enhance drainage and reduce soil compaction. Gypsum can also help in reclaiming sodic or saline soils by improving their water-holding capacity and reducing sodium levels. Gypsum is used as a fertilizer additive to provide calcium and sulfur to the soil. It helps in improving plant growth, root development, and nutrient uptake. Gypsum also aids in reducing soil erosion and improving soil structure. Plaster finds applications in various industrial settings. It is used in the production of casts and molds for Metal and Glass manufacturing. Plaster molds are employed in processes like investment casting, where they create intricate shapes for metal casting.

Ca and S Calcium and sulfur in raw gypsum meet the needs of pistachio trees for these two elements. The presence of a rich source of calcium in the subsoil or surface soil in pistachio gardens increases the soil acidity and reduces Al poisoning in it. Removable and very light plaster particles in the soil will greatly help to improve it`s properties. Calcium ions in the soil will increase light soil particles and also soil conditioning and lightening. On the other hand, SO4 sulfate ions will increase the absorption of fixed and non-absorbable ions for trees. According to many theories of plant nutritionists, calcium and sulfur are one of the most consumed elements, and in this regard, adding calcium and sulfur to the soil will meet the needs of trees for these vital elements. Applications of plaster in agriculture are generally in the following cases:

• Preparation of Chemical fertilizers
• Soil conditioner
• Preparation of chemical toxins
• Absorption of the soil moisture
• Improve soil structure and soften clay soils
• Supply of calcium required by plants
• Neutralization of sodium in alkaline soils
• Clarify the water of muddy ponds
• Activate microscopic creatures
• Supply of sulfur required by plants

According to above mentioned materials, plaster or gypsum is mainly used in construction industry mostly as a wall coating or for plastering artworks, but this useful material is also applicable in many industries such as agriculture, fertilizer, medicine, pharmaceutical, petrochemical, leather, glass, paper industries and so on. The use of raw plaster has an almost long history in agriculture and since 1768, i.e. about 250 years ago, plaster has been used to improve the soil. The use of plaster in agriculture has been popular in Europe since the 18th century on many crops, including grapes and apples.

Surprisingly, with all these extensive resources of raw plaster it`s use in some highly saline and alkaline pistachio Garden and pistachio-prone areas is very low and even very insignificant. A substance that can work miracle in pistachio garden, of course, if used properly. Another advantage of using raw gypsum in pistachio gardens is the reduction of salinity and its modification in the rhizosphere of the roots of pistachio trees, and another advantage is the acidification of highly alkaline soil in pistachio prone areas.

Plaster is a popular material for art and sculpture. Artists use plaster to create sculptures, reliefs, and intricate molds. It provides a versatile and easily workable medium for artists to express their creativity. Plaster sculptures can be finished with various techniques, such as Painting or gilding. Plaster plays a vital role in the ceramics and pottery industry. Plaster molds are used in the casting process to create ceramic objects. The liquid clay or slip is poured into the plaster mold, which absorbs the moisture, allowing the clay to solidify and take the shape of the mold. Plaster bats, which are flat plaster surfaces, are also used by potters for drying and working with clay.
