Litter production on natural and artificial fallow land in northern Ivory Coast

In the context of short and medium-term investigations to solve the problem of agricultural soil depletion in physicochemical elements in northern Cote d 'Ivoire, studies have been carried out in artificial fallows of tree legumes and natural fallows. Annual organic soil enrichment is important for Acacia auriculiformis (artificial fallow) and Isoberlinia doka (natural fallow) with litter production of 7.83 and 7.38 t / ha / year, respectively. AT With the exception of certain species, the most important litter production was obtained in the dry season (November to April). They accounted for 57% of annual production and increased with thunderstorm and harmattan (wind) periods in the region. The results of the work also identified indicators for seed crop planning based on pod falls. In the setting of investigations for short and long-term effects of agricultural chemistry in the North of Ivory Coast, studies were conducted on the arborescent leguminous artificial and natural fallows. The annual enrichment in organic matter with Acacia auriculiformis and Isoberlinia doka (natural fallow). The respective litter productions were 7.83 and 7.38 t / ha.year-1. With the exception of some species, the higher litter productions were yielded in dry season  (november to april). They represented 57% of the annual production and increased with storms and harmattan (wind) periods of the region. The results also identified to identify indicators of harvesting fall.
