Use as a Mulch
Coarser grade composts which consist of relatively large woody fragments are preferable for use as mulches as they do not decompose as readily as composts consisting of fine particles and remain in place for longer.
The surface of coarse materials dry out rapidly inhibiting weed seed germination. Therefore, avoid mulches that mainly consist of fine particles less than 10mm in size. Apply the compost evenly on the surface of the soil around the plants in the row to a depth of 50mm, creating a solid mat of compost mulch.
Avoid placing mulch against the tree trunk or main leader of the bush, as this can cause damage to the protective bark layer of the stem. Usually, compost that is high in soluble salts, reduce the amount of compost to be applied, and the mulch should be well watered.
Control of weed species is one of the most important effects of mulches. To suppress weeds physically, a 100mm thick mulch layer may be required. In general, the germination of weed seeds declines as burial depth increases.
Additionally, organic mulches gradually improve the physical and biological properties of the soil, because they decompose and become incorporated into the soil over a longer time. Compost has a similar effect to soil conditioners.
