“…Il ressort de cette étude que les trois (03) biofertilisants ont un rapport C/N compris entre 10 et 20 avec un pH neutre ou basique. Ces deux paramètres sont déterminant dans la maturité des composts formulés (Compaoré et al, 2010). En effet, les composts matures ont un pH compris entre 7 et 9 et un rapport C/N compris entre 10 et 20.…”

L’étude a porté sur les effets des amendements organiques sur la gale bactérienne et la pourriture apicale de la tomate en milieu réel à l’Ouest du Burkina Faso. Un essai a été mis en place dans un dispositif en bloc de Fisher complètement randomisé. Il a comporté huit (08) traitements constitués des fertilisants organiques et minéraux tous répétés quatre (04) fois. L’incidence de la maladie et sa sévérité ont été évaluées ainsi que l’effet des traitements sur la qualité des fruits. La progression est relativement faible avec les déchets ménagers compostés associés aux engrais minéraux. La maladie est plus sévère avec les différents fertilisants pris individuellement. Dans l’ensemble, la maladie est évolutive avec tous les traitements. The study focused on the effects of organic amendments on bacterial scab and apical rot of tomato in a real environment in western Burkina Faso. Indeed, a trial was set up in a completely randomized Fisher block design. It included eight (08) treatments consisting of organic and mineral fertilizers all repeated four (04) times. The incidence of the disease and its severity were evaluated as well as the effect of the treatments on the quality of the fruits. The disease is progressive with all treatments. However, the progression is relatively low with composted household waste associated with mineral fertilizers. The disease is more severe with the different fertilizers taken individually.

“…Open nutrient cycles in UPA systems may become a concern as balance studies demonstrated that excessive surplus of nutrients can lead to large volatilization and leaching losses during manure storage or after field application (Predotova et al 2010a, b;Diogo et al 2010a, b). On the other side, detailed studies indicate that regular manure and compost applications are necessary to maintain organic carbon balances in year-round cropped and intensively irrigated UPA plots (Lompo et al 2019).…”

“…Four contributions from Burkina Faso and/or Ghana focus on nutrient balances in urban vegetable production, thereby also testing the effects of biochar as a soil amendment. At UPAtypical fertilizer application levels exceeding official recommendations four-to seven-fold, apparent nutrient use efficiency of potassium (K) and nitrogen (N) ranged from 54 to 85% and from 44 to 66%, respectively (Lompo et al 2019). The application of 20 t ha -1 of biochar improved marketable average yields of different UPA crops by 6%, but yield increases were significant only on fertilized plots (Manka'abusi et al 2019).…”

The global challenge of rural-urban transformationDuring the last two decades the benefits, risks, negative externalities, and future social-ecological challenges of urban and (peri-) urban agriculture (UPA) have received increasing attention (Lydecker and Drechsel 2010;Safi and Buerkert 2011;Drechsel and Keraita 2014;Thebo et al. 2014). A main cause for this attention is the growing awareness of rapid ruralurban transformation processes that are changing matter flows, resource allocation, and ecosystem functioning as a consequence of strong shifts in the distribution of people along the rural-urban gradient (Cumming et al. 2014;Angel et al. 2005). It has been estimated that by 2050 the share of the global urban population may reach 68% compared with 55% today (United Nations 2017). Given continuing population growth, this phenomenon, in absolute numbers, entails
