This study was conducted at the level of the developed parts of two plateaus of the commune of Sokorbé. Multifunctional and classic half-moons were made on the degraded and encrusted soils of the Goubey and Sinsan plateaus. On each of these two units, soil profiles were opened and described and samples were also taken at the level of the dug parts and analyzed in the laboratory. Infiltration tests were conducted on the different compartments of the structure: impluvium, Zaï and bottom of the basin at the completion and after 1 and 2 years of operation. The results show that the organic matter rate increased from 0.8% on controls (impluviums) to 1.3% in the dug parts (zaïs and bottom of the basin) of the Goubey plateau and to more than 3.5% in those of the Sinsan plateau after one year of operation. However, this rate decreases after two campaigns (two harvests) and tends towards the initial situation in the zaïs. The acidic pH (4 to 4.2) on the controls increased towards neutrality (6 to 6.5) in the zaïs. As for the quantity of water infiltrated over a period of one hour, it varies between 116 and 190 liters per m2 on the controls to reach, after two years of operation, a volume varying between 378 and 396 liters per m2 in the dug parts, respectively on the Goubey and Sinsan plateaus. The making of half-moons on the degraded soils of the plateaus improves the physicochemical characteristics of all the compartments of the half-moons.

Abstract
This study was conducted at the level of the developed parts of two plateaus of the commune of Sokorbé. Multifunctional and classic half-moons were made on the degraded and encrusted soils of the Goubey and Sinsan plateaus. On each of these two units, soil profiles were opened and described and samples were also taken at the level of the dug parts and analyzed in the laboratory. Infiltration tests were conducted on the different compartments of the structure: impluvium, Zaï and bottom of the basin at the completion and after 1 and 2 years of operation. The results show that the organic matter rate increased from 0.8% on controls (impluviums) to 1.3% in the dug parts (zaïs and bottom of the basin) of the Goubey plateau and to more than 3.5% in those of the Sinsan plateau after one year of operation. However, this rate decreases after two campaigns (two harvests) and tends towards the initial situation in the zaïs. The acidic pH (4 to 4.2) on the controls increased towards neutrality (6 to 6.5) in the zaïs. As for the quantity of water infiltrated over a period of one hour, it varies between 116 and 190 liters per m2 on the controls to reach, after two years of operation, a volume varying between 378 and 396 liters per m2 in the dug parts, respectively on the Goubey and Sinsan plateaus.

Abstract: (french)
Cette étude a été conduite au niveau des parties aménagées de deux plateaux de la commune de Sokorbé. Des demi-lunes multifonctionnelles et classiques ont été confectionnées sur les sols dégradés et encroûtés du plateau de Goubey et celui de Sinsan. Sur chacune de ces deux unités, des profils pédologiques ont été ouverts et décrits et des échantillons ont été également prélevés au niveau des parties creusées et analysés au laboratoire. Des tests d’infiltration ont été conduits sur les différents compartiments de l’ouvrage: impluvium, Zaï et fond de cuvette à la réalisation et après 1 et 2 années de fonctionnement. Les résultats montrent que le taux de matière organique est passé de 0,8% sur témoins (impluviums) à 1,3% dans les parties creusées (zaïs et fond de cuvette) du plateau de Goubey et à plus de 3,5 % dans celles du plateau de Sinsan après un an de fonctionnement. Néanmoins ce taux diminue après deux campagnes (deux récoltes) et tend vers la situation initiale dans les zaïs. Le pH acide (4 à 4,2) sur témoins a augmenté vers la neutralité (6 à 6,5) dans les zaïs. Quant à quantité d’eau infiltrée sur une durée d’une heure, elle varie entre 116 et 190 litres par m2 sur les témoins pour atteindre, après deux ans de fonctionnement, un volume variant entre 378 et 396 litres par m2 dans les parties creusées, respectivement sur plateau de Goubey et Sinsan. La confection des demi-lunes sur les sols dégradés des plateaux améliore les caractéristiques physico-chimiques de tous les compartiments des demi-lunes.
