“…This might limit nutrient losses via lixiviation when not taken up by the crops. Ouandaogo et al (2021) reported for instance from the same trial, an increase of soil microbial biomass with the straw treatment up to 60 time of that of the control. In addition, Traoré et al (2016) investigating microbial nutrient limitation using soil from the same trial showed that carbon is the primary limiting factor of microbial growth.…”

“…The trial investigates the effects of different mineral and/or organic input regimes on soil productivity combined with crop rotations. It has already been used in numerous studies to highlight the importance of organic inputs and crop rotation in maintaining sorghum yields through improved chemical, physical and biological soil properties (Lompo et al, 2008;Ouandaogo et al, 2016;Traoré et al, 2016;Adams et al, 2020;Ouandaogo et al, 2021).…”

Information on long-term fertilization combined with crop rotation can contribute to better management of West African Lixisols. There is little information on how long-term organic inputs influence soil chemical properties under cereal monoculture versus a rotation with a legume. Here, we investigated how fertilization regimes with emphasis on organic inputs influence soil chemical properties in sorghum monoculture compared to sorghum-cowpea rotation. The long-term field trial of Saria in Burkina Faso, which has been in operation since 1960, was used for this purpose. Soils were sampled at the 0-20 cm depth to determine their organic C, total N, total P, mineral N, available P, pHwater, exchangeable basic cations, and cation exchange capacity. The best soil properties were exhibited with the application of 40 t ha-1 of manure. Recycling of sorghum residues combined with mineral fertilization led to a decrease in mineral N and available P but maintained a higher level of total N and P compared to exclusive mineral fertilization. Organic inputs determined soil properties and sorghum yield better (R2 = 0.89) in rotation than in monoculture. Our results show that a better productivity of the studied Lixisol requires an application of manure at more than 5 t ha-1 combined with mineral fertilization. In addition, a rotation including a legume and a regular recycling of crop residues is necessary.
