Abstract
Agricultural land management is one of the issues facing farmers in the semi-arid zones of West Africa. This study conducted in Burkina Faso aims at characterizing the physical properties of Ferric Lixisol under the influence of plowing, manure fertilization and sorghum monoculture. For this purpose, experimental designs of different ages were used at the agricultural Research Station of Saria and in farm plots located, on Ferric Lixisol. The cropping practices tested combined plowing with different rates of farmyard manure. Soil physical properties analysis showed that the annual plowing with farmyard manure application resulted in a 1.6-point decrease in structural porosity and a 57% decrease in fine silt content after 33 years of cultivation, compared to soils under farm plots. Steady-state infiltration was reduced by 58% compared to that measured under natural fallow. These changes were much linked to the plowing intensity than to the organic fertilizer rates. On the other hand, after 33 years of cultivation, the biennial plowing of 40 t ha-1 of manure resulted in a loss of more than 50% of the soil’s clay and iron oxy-hydroxide contents of the soil compared to plots without manure and those of the farmers. In conclusion, unjustified intensification of cultivation practices can lead to a degradation of soil physical properties.
