Made by the action of sulphuric acid on raw rock phosphate (also called Appatite) this is one of the world's most important fertilisers, and probable one of the oldest inorganic ones. Partly soluble and a usable form of phosphorous by plants, it must be well dug in. Ideal for feeding root vegetables such as carrots and beetroot, it also assists in seed germination. Use in soils containing a sufficiency of lime so as not to waste this valuable nutrient through poor plant uptake.
Application rate: 70g sq. m. Dig in well.
