To obtain a mulch, the weeds are cut, heaped, and allowed to rot, and then mixed with dried grass and leaves. The effect of a layer of this is to keep the soil in a moist, porous con-dition. It also has value as a manure. According to the West Indian Bulletin, Vol. 10, No. 2, the grass from one acre of cacao plantation contains—

In certain countries, Grenada and Ceylon for examples, applications of pen or farmyard manure are made. This is a costly process, but so valuable is it, that it is to be regretted that all planters cannot either run a stock and grazing farm or else have their plantation in close proximity to one.
