Moulding in agriculture is quite simple but can be dirty work. this is is usually when soil is scraped up and heaped around the base of a plant to form a small mound using a hoe or trowel. this can also be done by using plastic as shown in the above picture.
This will prevent the soil around the plant from washing away which would result in the plant being bear and easier to be uprooted by wind and rain. this also add better aeration for the plant in accordance to the soil.
