Perspective d'utilisation des termitières dans l'amélioration de la fertilité des sols tropicaux : cas d'une expérimentation en pots de végétation

Abstract

Perspective of termitary mounds utilization in improvement of tropical soil fertility : case of a pot vegetation experiment. The fertilizing power offive termitary mounds of Yakonde soil serie (Y2) in Yangambi has been tested by rice growing in vegetation pots and compared with those of host soil 's and complex manure's. The obtained data have shown that termitary soils are more fertile than host soil, butless than complex manure. Among five forms of termitary mounds tested, "semi-arboricole" form proved to be efficient. Then, utilization of different forms of termitary soils as fertilizing materials in tropical regions appears possible, because of their wealth in nutrient elements for plants, abundance in tropical forests and easy get by tropical peasant.
