Abstract:
Background: Techniques of plant recolonization are increasingly developed throughout the world. In Cameroon, Revitalization Technology (ReviTec) was implemented in the Sudano-Sahelin zone in order to evaluate its impact on the rapid restoration of degraded soil and plants colonization.
Aim: The aim of this work was to identify the good treatment (composition of different nutrients) involving the fast plants appearance.
Method: The plant cover estimation as well as the evaluation of the presence of plants species by island within the quadrats of 1×1m2 was done. The method used to fight these ominous phenomena is the ReviTec. The software Stagraphics and Xl-stats were used for the different analyses.
Results: The results showed that the treatments CpBcMy (42 species) present a considerable number of species. The frequency indices present a heterogeneous vegetation with the predominance of accidental species (53%) in the experimental site. The most represented families were those of Fabaceae cesalpinioideae, Poaceae, Malvaceae and Rubiaceae. Stylosanthes guianensis and Brachiaria brizantha were the most represented species with 94.22% and 95.11% respectively. Zoochory was the most frequent type of diaspores dispersal with 51.76%. The most important percentage cover was observed in the treatment CpBcMy (32% on the average).
Conclusion: The present approach used for the restoration of degraded soils is very beneficial for plants succession and maintenance of cover percentage to highest rate.
