FIELD: chemistry.
SUBSTANCE: invention relates to fertiliser elements, which contain core consisted of azote, phosphorous and/or potassium as a nutrient, and covered with a coating agent. The core is covered with both binding agent and coating agent that has non-organic substance which takes up free water as composition water. The non-organic substance is calcium sulphate hemihydrate and/or chemically active calcium sulphate anhydride. The coating agent contains dolomite, magnesium sulphate, calcium carbonate, potassium sulphate and/or sodium sulphate. The binding agent contains compound, which hardens and releases water during polymerisation and can be corresponds to urea formaldehyde substance.
EFFECT: decrease tendency to caking ability, dust formation, enhancement of mechanical resistance of fertiliser elements.
