The Iron content will help to keep the moss at bay and the Magnesium Oxide helps maintain the Magnesium levels in the soil which is part of the chlorophyll essential for photosynthesis.

Iron is a trace element used in many fertilisers, but alone it is mainly used on lawns. It helps with diseases such as fusarium patch and take-all patch, as well as helping with worm control. Its most common use is as a moss killer.
