Croissance en pots de quatre espèces végétales sur des substrats enrichis avec la terre de termitières de Cubitermes
Abstract
Growth Study in Pots of Various Plants Species on Substrates Enriched by Termite Mounds Cubitermes. The different parts of Cubitermes mounds (cap, trunk and base) from Burkina Faso were analyzed and proved to be richer in available phosphorus, carbon and NO3-N and much richer in NH4-N than the surrounding soil. Their possible stimulating effect was tested on the seedling's growth of four species: Acacia holosericea (A. Cunn. ex G. Don.), Acacia raddiana (Sav.), Crotalaria ochroleuca (G. Don.) and Sorghum sp. (L.) during 47 days. An acceleration of growth is observed for Sorghum on the substrates containing powder 50% of cap or column. This acceleration becomes significant only from 26 days. A similar growth is observed for Crotalaria but as from 40 days.
