*7.3.3 Weed infestation*

The partially decomposed organic mulch materials could act as carriers of various weed seeds. Incorporation of mulch to a deeper depth could help to mitigate the problem of weed seed because at a deep depth the growth of weeds is suppressed before getting to the surface. Organic mulch can inhibit the growth of weeds by depleting air and resources necessary for their growth, thereby promoting healthy plants and soil. Previous study has shown that weed suppression is directly related to the depth of mulch [30]. Organic mulches that are applied at a higher depth can reduce weed species as compared to those applied at shallow depths.
