Granular lime  promotes soil fertility.

Lime stimulates the developmentof micro-organisms in the soil,  such as bacteria and fungi, which ensures the digestion of plant residue runs optimally. Lime regulates the acidity (pH) in the soil, which neutralises and prevents acidification.
Lime promotes the absorption of nutrients that are essential to plants, such as nitrogen, phosphate, potassium and magnesium.

Indirectly works against moss.
