Effect of agroecological practices on cultivated lixisol fertility in eastern Burkina Faso

Abstract

Conservation and restoration of degraded agricultural soils are in fact two important factors of resilient agrosystems and food sovereignty in the context of global change in the Sudano-Sahelian zone. The objective of this study is to determine the effect of adaptive practices for the conservation and restoration of degraded agricultural lixisol. Soil organic carbon, total nitrogen, pH and soil microbiological activity were evaluated in soils surface layers on cultivated plots developed in zaï (Z) and in stone-rows (SR) with contribution of compost (C) since 2006, traditional practices (absolute witness AW) and uncultivated natural vegetation (NV) soils. The results showed that agroecological practices improve soil pH, organic carbon, total nitrogen, electrical conductivity and available phosphorous compared to the absolute witnesses. There was also a decrease in the C/N ratio on the agroecological field relative to the controls. These practices had a positive effect on soil mineralization potential and the soil microorganism's diversity. Substrate-induced respiration (SIR) for 15 carbon sources using the MicroResp technique under agroecological practices and natural vegetation were much higher than those under the absolute witness. Agroecological practices have a positive effect on the different parameters of soil fertility in the semi-arid zone and can thus restore degraded soils.

Enhancement of proline content and antioxidant enzyme activities induced by drought stress in maize (<i>Zea mays L.</i>) by application of compost

“…Similar results have already been obtained by Meskelu et al (2014). This reduction is explained by Imorou et al (2018) by reducing the leaf area (photosynthesis site) and stem elongation, by decreasing the number of grains due to poor fertilization (at bloom stage) or by the reduced accumulation of starch in the endosperm (at the milky-grained stage). However, this decrease in aerial biomass remains low for compost crops in favor of grain production and filling (Imorou et al, 2018).…”

“…Dado que los terrenos evaluados presentan una orografía accidentada y distribución florística aleatoria, se propone diseñar arreglos de distribución más uniforme, utilizando la metodología de curvas a nivel para el estrato arbóreo y arbustivo, quien de acuerdo con Coulibaly et al (2018); Tejeda et al (2021) y Nabati et al (2022, esto evitará la pérdida de suelo y coadyuvará a la retención de humedad, permitiendo un mejor desarrollo de los componentes productivos.…”

Prévalence de la cysticercose porcine à <i>Taenia solium</i> (<i>Cysticercus cellulosae</i>) chez les porcs dans l’aire d’abattage de Kinsoundi à Brazzaville

“…Elle est beaucoup inférieure aux prévalences de 5,6 % et 4,6 % rapportées respectivement par Eshitera et al (2012) au Kenya et Porphyre et al (2015) à Madagascar. Mais elle est supérieure à la prévalence de 0,87 % observée au Bénin par Goussanou et al (2014) cités par Dahourou et al (2018).…”

“…». Notre prévalence globale est également supérieure aux prévalences globales observées dans le sud du Sénégal (0,1%) et en Gambie (0,2%) par Secka et al (2010); et au Burkina Faso (0,22 %) par Dahourou et al (2018).…”
