  abstract = {{F}allows and livestock manure are the main means for improving the fertility of agro-pastoral systems in {W}est {A}frican {S}ahel. {A}s the general shortage of cropland has led to shorter fallow periods, manure appears to be the only means of maintaining soil productivity. {S}everal studies have focused on the general pattern of nutrient release from manure but, so far as we are aware, few studies have investigated the long-term changes of manure input to tropical soils. {T}his research project was carried out on ferralic arenosol in north {B}urkina {F}aso to assess the longterm residual effect of organic matter (sheep and goat manure) on land where livestock had been corralled. {M}icrobial activities, soil organic matter and vegetal production were evaluated and a soil organic matter model was then drawn up and fitted to the data. {T}he residual effect decreased rapidly during the first 5 years after corralling but remained significant for up to 11 years. {T}he duration and magnitude of the residual effect depended mainly on the amount of manure applied. {T}he differences in soil organic matter recorded between plots that had not been corralled for many years might result from the different amounts of manure applied in the past. {V}egetal production and denitrification potentials were negligible below a minimum soil organic matter threshold. {T}he initial soil organic matter level, the soil organic matter threshold and the residual effect of corralling should be taken in account when advising on the management of ecosystem services such as vegetal production and control of greenhouse gas emissions. {F}or these purposes, it could be useful to produce a more advanced model.},
