“…In retrospect, only microdose treatments (improved and farmer practice) showed the best biomass yield of 12,708 kg ha −1 , 10% higher than that of broadcasting. This observation could be linked to the significant effect of the mineralization of the stock of organic matter that was placed basally in the seeding holes [28,32]. Compost with microdosing at 2.5 t ha −1 is also critical for the development of above-ground biomass under sufficient rainfall conditions, which would be beneficial to agro-pastoralists, especially for animal fodder.…”

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.

“…La dissolution rapide du TSP, créant un environnement favorable au développement du système racinaire, favorise de ce fait la solubilisation du phosphate naturel (Akande, 2011 ;kouyaté et al, 2020). Le phosphate naturel calciné (PNC) utilisé sans combinaison avec le TSP seul n'a pas eu un impact significatif sur les réserves de phosphore dans les sols pour les deux cultures.…”

Description du sujet. La calcination offre une opportunité de solubiliser le Burkina phosphate naturel afin d’accroitre son efficacité agronomique sur les sols pauvres en phosphore.Objectif. La présente étude menée à la station expérimentale de Kamboinsé de l'Institut de l'Environnement et de Recherches Agricoles (Ouagadougou, Burkina Faso), a pour objectif d'examiner la contribution du phosphate naturel calciné à l’amélioration de quelques propriétés chimiques des sols ferrugineux tropicaux lessivés sous culture de sorgho (Sorghum bicolor (L.) Moench) et de niébé (Vigna unguiculata (L.) Walp).Méthodes. Les traitements suivants ont été comparés à l’aide de blocs de Fisher complètement randomisés pour le sorgho et le niébé séparément de 2021 à 2022 : Témoin, Matière Organique (MO), Burkina phosphate naturel (BP, 23 kg ha-1 P), Phosphate naturel calciné (PNC, 23 kg ha-1 P), Triple superphosphate (TSP, 23 kg ha-1 P), engrais complexe (NPK 14-23-14), PNC 50 + TSP 50, PNC 75 + TSP 25, et PNC 25 + TSP 75.La quantité d’azote (N) fournie était de 37 kg ha-1 pour le sorgho et 14 kg ha-1 pour le niébé, celle de phosphore (P) et de potassium (K) étaient respectivement de 23 kg ha-1 et 14 kg ha-1 pour tous les traitements, sauf le Témoin et la MO. Ces quantités ont été appliquées sur des micro parcelles de 20 m2.Résultats. Les résultats obtenus ont indiqué que c'est la combinaison du PNC avec le TSP qui a eu un impact significatif sur la disponibilité de phosphore assimilable et les bases échangeables dans le sol. Les niveaux de phosphore stockés étaient plus élevés avec les combinaisons PNC 50 + TSP 50 (100,2 ± 13,3 %) pour le niébé et PNC 75 + TSP 25 (17,34 ± 6,49 %) pour le sorgho. L'application de PNC seul a également entraîné une augmentation significative des bases échangeables, de la capacité d'échange cationique (CEC) et de la saturation du sol. Ces traitements ont conduit à une augmentation annuelle des bases échangeables et de la capacité de stockage du sol en ions.Conclusion. Pour gérer efficacement la fertilité des sols ferrugineux tropicaux lessivés, il est nécessaire d’intégrer judicieusement l'utilisation du phosphate naturel calciné dans les pratiques de fertilisation. Description of the subject. Calcination is an opportunity to improve Burkina phosphate rock solubility and its agronomic efficiency.Objective. The present study, conducted at the Kamboinsé station of the Institute of Environmental and Agricultural Research (Ouagadougou, Burkina Faso), aimed to examine the contribution of calcined phosphate rock to the improvement of certain chemical properties of leached tropical ferruginous soils under sorghum (Sorghum bicolor (L.) Moench) and cowpea (Vigna unguiculata (L.) Walp) cultivation.Methods. The following treatments were compared in randomized bloc design for sorghum and cowpea separately from 2021 to 2022: Control, Organic Matter (OM), Burkina phosphate rock (BP, 23 kg ha-1 P), Calcined Phosphate Rock (PNC, 23 kg ha-1 P), TSP (23 kg ha-1 P), NPK (14-23-14), PNC 50 + TSP 50, PNC 75 + TSP 25, and PNC 25 + TSP 75. Similar amounts of N, P, and K were applied in all treatments, except for the Control and OM. The amount of nitrogen was 37 kg ha-1 for sorghum and 14 kg ha-1 for cowpea, those of phosphorus and potassium were 23 kg ha-1 and 14 kg ha-1 respectively for all crops and treatments except the control and OM. These amounts were applied in plot of 20 m2 area.Results. The results indicated that the combination of PNC with TSP had a significant impact on the availability of a phosphorus and exchangeable bases of the soil. Phosphorus storage levels were higher with the PNC 50 + TSP 50 combination (100.2 ± 13.3 %) for cowpea and PNC 75 + TSP 25 (17.34 ± 6.49 %) for sorghum. The application of PNC alone also resulted in a significant increase in exchangeable bases, cation exchange capacity (CEC), and soil saturation. The treatments led to an annual increase in exchangeable bases and ion storage capacity in the soil.Conclusion. It is possible to effectively manage the fertility of leached tropical ferruginous soils by incorporating the use of calcined phosphate rock into fertilization practices.

“…Reduced carbon or organic matter could affect the soil's water retention capacity and nutrient content, affecting soil fertility. Thus, phosphorus is one of the main limiting factors in agricultural production [3] in tropical regions. To improve soil productivity, the population is continuously seeking fertile soils for its agricultural or pastoral activities.…”

Soil data are essential to know the soils and improve agricultural yields, especially in a locality like Yilou in Burkina Faso. Soil samples were taken from five soil types, namely FLIPP, FLTC, FLIMP, BEHV/F and hydromorphic. The morphological and physicochemical parameters were studied according to the national reference of Burkina Faso. The results of the soil analyzes were compared with reference standard values. The morphological aspect indicates that FLIPP had a light yellowish brown (10YR 6/4) horizon at the beginning and becomes pale brown (10YR/6-3). FLIMP ranged from yellowish brown (10YR5/4) to yellowish yellow (10YR6/6) and BEHV/F had a pale reddish brown horizon (2.5YR6/3-2.5YR6/4). FLTC had a yellowish brown (10YR5/4) matrix color in the first 20 cm and turns light brown (7.5YR5/6) in the next three horizons. The hydromorphic soils were gray at the surface (2.5Y 5/1) and light brown gray (2.5Y 6/2) at depth. The textures of soils were sandy loams (FLIPP, FLTC, FLIMP and BEHV/F) and sandy clay loams (BEHV/F/F, hydromorphic). The soils were slightly acidic (Hydromorphic, FLIPP and FLTC), and slightly alkaline (FLIMP and BEHV/F) with an organic matter below the reference standard (3.6% <OM<6.5%). Hydromorphic soils had the level of very high fertility (OM>2). The total nitrogen content was lower (1.2-2.2%), except for hydromorphic soils (1.81%). The soils had a C/N ratio of 11, except for FLTC soils where C/N ratio was 10 below the baseline standard of 11-15. Hydromorphic and BEHV/F soils had the highest levels of assimilable phosphorus with respective values of 6.24 mg/Kg and 4.65 mg/Kg. The iron levels of the five soils varied from 968 to 1423 mg/Kg. Soils were low in exchangeable cations and the highest level was found in hydromorphic soils (8.37 meq (+)/100g) but remains below to reference standards (10 <CEC< 20). BEHV/F and hydromorphic soils were most fertile.
