“…These results can be attributed to the nitrogen use efficiency of 22 kg of sorghum grain per kg of nitrogen with the application of the compost microdose at 2.5 t ha −1 + 100 kg ha −1 DAP, compared to only 8 kg of grain per kg of nitrogen with the application of 5 t ha −1 + 100 kg ha −1 DAP. The application of 56.25 g of compost per plant hole ensures a concentrated supply of nutrients to the plants, reduces losses [33,34], and improves the chemical, physical, and biological properties of soils for subsequent crops in the rotation [35,36]. Although the benefits of microdosing have been demonstrated by several studies [29,37], we found that its contribution to the soil fertility restoration, especially nitrogen (N), was less than that of the application of 5 t ha −1 by broadcasting.…”

The depletion of soil organic matter is one of the major challenges constraining agricultural production in the southern zone of Mali. This study evaluated the effects of compost types, methods, and dose applications on the productivity and sustainability of sorghum. Two types of compost (farmer practice and cotton stems) were applied to sorghum at two rates (microdosing at 2.5 t ha−1 and broadcasting at 5 t ha−1) and evaluated on 30 farmer fields in 2019 and 2020. The treatments used included CPA (cotton stem compost at 5 t ha−1 + 100 kg ha−1 DAP), CPA (cotton stem compost at 2.5 t ha−1 + 100 kg ha−1 DAP), CP (farmer compost at 5 t ha−1 + 100 kg ha−1 DAP), CP (famer compost at 2.5 t ha−1 + 100 kg ha−1 DAP), control (100 kg ha−1 DAP), and control. The results showed that regardless of the compost type, applying a microdose of 2.5 t ha−1 improved the growth rate, plant height, grain yield, and biomass yield by 15%, 18%, 47%, and 27%, respectively, when compared to the control. No statistical difference was observed in the yield of 2061 kg ha−1 between applying compost by microdosing at 2.5 t ha−1 and broadcasting at 5 t ha−1. It can be inferred that the application of compost by microdosing makes it possible to achieve a 100% fertilized surface compared to broadcasting, with a nitrogen use efficiency of more than 55%. The application of compost by microdosing at 2.5 t ha−1 resulted in an economic gain of 334800 XOF ha−1, which was 27% less than that obtained with the application of compost by broadcasting at 5 t ha−1. Conversely, the contribution to the improvement of soil nitrogen stock varied from 12–20% with a microdose of 2.5 t ha−1 compared to 100% for broadcasting compost at 5 t ha−1 per application. Therefore, the availability of cotton stems in the southern zone of Mali presents an opportunity for farmers to implement compost microdose technology to double the fertilized area and improve sorghum productivity.

“…This increase may be due to: the added organic manure at establishment (at a rate of 2.500 kg/ha), input of leaf litter, root turnover and potentially higher levels of soil microbes (Bernoux and Chevalier 2013). The study by Doumbia et al (2020) in Mali showed that planting Gliricidia sepium in the corridor increased the organic carbon and total nitrogen content in the soils between the alleys by 5% after three years. Similarly, this study also showed that the application of mulch produced from Gliricidia sepium on crops allowed to maintain and improve the physical and chemical properties of soils ( sequestration in soils.…”

The objective of this work was to carry out a long-term monitoring of shrub fodder banks (SFB), established under the real-low-input-farm conditions of Burkina Faso, characterised by a Sudano-Sahelian climate type with wide variations in rainfall. The SFBs, which were planted in 2016-2017 with Leucaena leucocephala (LL) and Morus alba (MA) at a high-density (20,000 plants/ha), were monitored from 2016/2017 to 2021 for their biomass (fodder) production, chemical composition and nutritive value of the edible forage, and their impacts on soil carbon content. The average annual forage production of LL for the 6 SFBs (1, 2, 3, 4, 5 and 6) was 11.4 ± 2.12 t DM/ha/year while that of MA was 3.8 ± 1.2 t DM/ha/year for the 3 SFB (1, 2, and 3). Such differences are likely related to higher adaptive capacity for LL in such climatic conditions. The high nutritive value observed in both fodder resources agreed with available literature worldwide. Crude protein was higher in LL (19% vs. 17%), but dry matter digestibility (65% vs 77%) were superior in MA. Soil carbon increased during the five monitored years, which is an interesting result for these poor, low fertility soil conditions. Our results demonstrate the technical and environmental feasibility for establishing this low-input agroforestry technology in these conditions, as an agroecological alternative to overcoming feed shortages for local livestock farming. However, the successful management of a SFB relies on the selection of the right species, the protection provided, and the management during the establishment and fodder production periods, with suitable cutting frequency and appropriate post-harvest management.

“…Cependant, les sols utilisés pour leur production sont naturellement pauvres en éléments nutritifs nécessaires au développement harmonieux des plantes (Somda et al, 2017). En plus, les effets conjugués de pratiques agricoles inappropriées et des effets négatifs du changement climatique menacent la production agricole en zone sahélienne (Doumbia et al, 2020). Bien que les engrais minéraux soient efficaces pour augmenter les rendements des cultures, leur utilisation dans cette région Afrique subsaharienne reste faible.…”

L’inadéquation de la fertilisation minérale est une contrainte qui limite la production du sorgho et du mil au Burkina Faso. Cette étude vise à déterminer l’effet des nutriments secondaires et des micronutriments (NSM) dans la production du sorgho et du mil sur des sols ferrugineux tropicaux lessivés du Burkina Faso. Elle a été conduite en station expérimentale à Saria de 2018 à 2019. Le dispositif expérimental est constitué d’un bloc de Fisher avec trois répétitions. Sept traitements ont été comparés : Témoin (0), NPK (60-15-20), NPK+S (60-15-20-15S), NPK+Mg (60-15-20-10Mg), NPK+Zn (60-15-20-2,5Zn), NPK+B (60-15-20-0,5B) et Complet (60-15-20-15S-10Mg-2,5Zn-0,5B). Le rendement grain du sorgho a été significativement augmenté avec les traitements combinant les NSM au macronutriment. Contrairement au sorgho, cette combinaison a entraîné une baisse des rendements grain du mil. Les rendements grains du sorgho ont augmenté de 40% en 2018 avec les traitements Complet, NPK+S, NPK+Zn et NPK+Mg. En 2019, ces augmentations ont été de 53%, 23% et 16% respectivement avec les traitements Complet, NPK+B et NPK+S par rapport au NPK. L’apport d’engrais composé de NPK combiné au NSM et à la matière organique est une alternative pour accroître durablement les rendements des céréales. The inadequacy of mineral fertilization is a constraint that limits the production of sorghum and millet in Burkina Faso. This study aimed at determining the effect of secondary nutrients and micronutrients (NSM) in the production of cereals on leached tropical ferruginous soils from Burkina Faso. It was conducted in the Saria experimental station from 2018 to 2019. The experimental design consisted of a Fisher block with three repetitions. Seven treatments were compared: Control without fertilizers (0), NPK (60-15-20), NPK + S (60-15-20-15S), NPK + Mg (60-15-20-10Mg), NPK + Zn (60-15-20-2,5Zn), NPK + B (60-15-20-0,5B) and Complete (60-15-20-15S-10Mg-2,5 Zn-0,5B). The grain yield of sorghum was significantly increased with the addition of NSM to the NPK. However, millet grain yield was decline with NSM addition to NPK treatment. The Complete, NPK + S, NPK + Zn and NPK + Mg treatments showed 40% increasing in grain yield of sorghum compared to NPK in 2018. Complete, NPK + B and NPK + S treatments which increased the grain yield of sorghum by 53%, 23% and 16% respectively in 2019. Adding NPK fertilizer combined with NSM and organic matter is an alternative to achieve sustainable increasing of grains yields.
