To ensure the optimum yield of cultivated land, farmers often use chemicals (fertilizers, pesticides, herbicides). However, these chemicals are not without adverse effects on the environment and on the health of humans and all other living beings. The fact remains that palliative solutions to chemical fertilizers exist in natural fertilizers, namely manure, slurry, compost, comfrey, chicken droppings, bat droppings (guano), powder termite mounds. For the latter, some studies have been conducted with sometimes contradictory results, and above all, they do not mention the type of termite mound used. Thus, in this work, the fertilizing effects of three types of termite mounds encountered in the savannahs and forests of Africa (epigeal termite mound, arboreal termite mound and hypogeal termite mound), were highlighted then their fertilizing powers to that of N15P15K15 on the growth and development of tomato in the nursery were compared. The results obtained showed that termite mound powders like N15P15K15 have a fertilizing power on tomato cultivation in the nursery. But N15P15K15 and tree termite mound powder seem to perform better. However, when we consider the action of the different termite mound powders between them, another gradient of fertility appears according to its origin. The fertilizing power is high for the arboreal termite mound, medium for the hypogeal termite mound and low for the epigeal termite mound.
