Soils degradation in Benin is most commonly reported thread for the agricultural production and this situation became more crucial in the Centre of Benin. This study has been carried out to evaluate the contribution of farmer's soil conservation practices to combat soil erosion in the agricultural watershed of Linsinlin. A field experiment was conducted on loamy-sand soil using Fisher Block design under researcher management. The factors which testified during study were tillage and mulching. The "Runoff plot" system was installed to collect erosion data. Three rainfall episodes viz, June 15, 19 and 27, 2016 with 52, 27 and 57 mm of water were used for the data collection. Rain distribution was measured for each rainy episode using a rain gauge. These three rainy episodes constitute a repetition. Results of study revealed that tillage and mulching treatment significantly decrease runoff, soil loss and nutrients loss (nitrogen, available phosphorus, potassium, magnesium). In case of nutrient lose, highest amount of nitrogen and potassium were lost. The interactive effect of tillage system and mulching was significant on runoff, soil and nutrient loss. The treatment combining isohypse ridging with mulching practice reduced total runoff from 6.27% to 0%, soil loss 2028 kg.ha
Soils degradation is one of the constraints in food security achievement in Benin. This study aimed at assessing the effect of cropping systems and slope on soil physical and chemical properties in the watershed of Kpacomey located in the Aplahoué district. Soil samples were collected from three parallel transects along the slope. Sampling was carried out under different treatments combining cropping systems (Maize-Cassava, pure Palm grove, Palm grove-Maize-Cassava and Teak Plantation) along with slope levels (low slope, medium slope and high slope degree). The impact of cropping systems and slope on soil properties was assessed by determining the physical and chemical parameters. The cropping systems significantly (p < 0.05) influenced soil bulk density, root biomass, soil acidity and soil organic matter. The lowest soil bulk density (1.38 g/cm 3) was recorded under the Palm grove-Maize-Cassava cropping system while the highest (1.47 g/cm 3) was obtained with pure Palm grove cropping system. Root biomass was more abundant (0.28%) with the pure Palm grove cropping system. However, root biomass was significantly (p < 0.05) influenced by slope. Soil crusting resulted in no significant influence (p > 0.05) on the effect of cropping systems and slope. Moreover, cropping systems resulted in significant effects (p < 0.05).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
