Root-Gyp is a naturally mined product that is verified for use as a fertiliser within organic farming systems. The product is mined in Newark, Nottinghamshire by Saint Gobain Formula through British Gypsum, with Rootwise Ltd being their preferred supplier throughout the UK.

Root-Gyp is produced from the processing of the Gypsum mineral, Calcium Sulphate Dihydrate (CaS04.2H20) and provides an excellent source of Calcium and Sulphate which is highly soluble and pH neutral. The product is manufactured from a naturally occurring mineral and therefore variations in colour and non-gypsum content are to be expected.

This product has a unique blend of properties that contribute to the Cation Exchange Capacity (CEC) and nutrient storage in the soil. The relationship between the elements, namely Calcium, Magnesium, Potassium and Sodium as positively charged ions is vital in crop production and has been seen to benefit many arable farmers.

Product only available in bulk.
