land plaster
Very LowTechnical/Archaic
Definition
Meaning
Gypsum (calcium sulphate) spread on soil as a fertilizer and soil conditioner.
A historical agricultural term for ground gypsum used to improve soil structure and fertility, especially in clay soils, by helping to break up compacted earth and provide calcium and sulphur. The term is now largely archaic, replaced by 'gypsum' or 'soil amendment'.
Linguistics
Semantic Notes
The term 'plaster' here refers to its powdery, spreadable form, not its construction use. It combines 'land' (agricultural) with 'plaster' (the material). It is a compound noun where the first element specifies the domain of use.

FAQ
Frequently Asked Questions
No, the term is archaic. The material (gypsum) is still used in agriculture, but it is referred to as 'gypsum' or a 'soil amendment'.
No. While chemically similar to some building plasters, 'land plaster' specifically refers to the agricultural-grade material used on soil, not for construction.
Yes. Land plaster is typically the dihydrate form of calcium sulphate (gypsum). Plaster of Paris is the hemihydrate form, calcined for use in casts and moulds. They are related but processed differently for different purposes.
Because the material is in a fine, powdery form that can be 'plastered' or spread thinly over a surface, similar to how medicinal plaster or building plaster is applied.
