“…The studies included in our analysis satisfied the following criteria: (1) Studies focused on maize production with substitution of mineral fertilizer with organic fertilizer, including animal manure (47%), compost (37%), commercial organic fertilizer (e.g., industrially processed, standardized poultry or livestock manure; 9%), digestate (5%), slurry (2%); (2) The amounts of applied organic material and the N content were clearly specified; (3) The mineral fertilizer treatment and "substitution treatments" (partial or full substitution of chemical with organic fertilizer) had identical total N rates, and phosphorus (P) and potassium (K) inputs were not major factors limiting maize growth; (4) The N application rates for each treatment were reported to allow calculation of the Rs, defined as organic N input/total N applied; (5) Field or lysimeter study, with articles reporting data from the same experiment excluded; and (6) Experimental duration of at least 3 years with respect to the effects of organic fertilizer on soil properties (e.g., SOC) [20]. In total, 133 published articles performed worldwide were included in the analysis (see supporting information for details).…”

Organic fertilizer is an effective substitute for mineral fertilizer that improves crop yield and is environmentally friendly. However, the effects of substitution often vary due to complicated interactions among the organic fertilizer substitution rate (Rs), total nutrient supply, and type of cropping system used. We performed a meta-analysis of 133 maize studies, conducted worldwide, to assess maize yield and environmental performance with substitution of mineral fertilizer with organic fertilizer. At an equivalent nitrogen (N) rate, substituting mineral fertilizer with organic fertilizer increased maize yield by 4.22%, reduced NH3 volatilization by 64.8%, reduced N leaching and runoff by 26.9%, and increased CO2 emissions by 26.8%; however, it had no significant effect on N2O or CH4 emissions. Moreover, substitution with organic fertilizer increased the soil organic carbon sequestration rate by 925 kg C ha−1 yr−1 and decreased the global warming potential by 116 kg CO2 eq ha−1 compared with mineral fertilizer treatment. The net global warming potential after organic fertilizer substitution was −3507 kg CO2 eq ha−1, indicating a net carbon sink. Furthermore, the effect of organic fertilizer substitution varied with the fertilization rate, Rs, and treatment duration. Maize yield and nitrogen use efficiency tended to increase with increasing N application rate following substitution of mineral fertilizer with organic fertilizer. Full substitution reduced N losses more than partial substitution. Further analysis revealed that the yield-optimal Rs for organic N in maize production was 40–60%. Moreover, maize yield and nitrogen use efficiency were further increased after long-term (≥ 3 years) combined use of organic and mineral fertilizers. These findings suggest that rational use of organic and mineral fertilizers improves maize productivity, increases soil organic carbon sequestration, and reduces N and C losses.

“…Previous studies examined the economic profitability of fertilizer microdosing using various approaches. Some studies used net income (Tabo et al, 2007), the benefit-cost ratio (Bielders and Gérard, 2015;Sime and Aune, 2014) and marginal value cost ratio (Camara et al, 2013;Liverpool-Tassie et al, 2015;Tovihoudji et al, 2018). Compared to other approaches, marginal value cost ratio (MVCR) examines the incremental change in net income when the investment cost increases and it takes into account additional costs generated by the new technology (Kelly, 2006;Boughton et al, 1990).…”

“…However, the analysis of these studies revealed that not all the additional costs such as labor cost were taken into account particularly in the economic profitability evaluation of fertilizer microdosing. Indeed, the application of fertilizer microdosing generates an additional cost in terms of labor due to the greater effort needed to bury the fertilizer compared to the traditional practices (Liverpool-Tasie et al, 2015;Pender et al, 2008;Tovihoudji et al, 2018). In addition, analysis of the results of empirical studies indicated that labor availability would be one of the main constraints affecting fertilizer microdosing adoption (Okebalama et al, 2016;Tabo et al, 2007).…”

This paper analyses the effect of labor opportunity cost on economic profitability of fertilizer microdosing (FM) in Burkina Faso. In order to assess the incremental change in net income when the investment cost increases and takes into account labor opportunity cost, the marginal value cost ratio (MVCR) approach is used. Using data from farmer's field, the results showed that for both crops, the median yield of the fertilizer microdosing plots is 500 kg.ha-1 , which is slightly higher than yield from recommended dose plots. Moreover, the rate of fertilizer microdosing plots of millet with a marginal value cost ratio above 2 shifts from 50% (without labor opportunity cost) to 41% (with labor opportunity cost) and not even one recommended dose plots reached this threshold. These findings argued that fertilizer microdosing adopters remain economically profitable for farmers compared to traditional practices despite the opportunity cost of labor. However, because of its importance in the process of fertilizer microdosing adoption, labor costs must be included in its economic evaluation. The results of this study confirm the need to accelerate mechanization of fertilizer microdosing application.

“…The intensification of agricultural production to increase crop productivity on limited arable land is important to guarantee food availability and the positive role of mineral fertilizers (reduction of soil nutrient mining) within such cropping system is undeniable (Bindraban et al, 2015). The efficient use of mineral fertilizers through their micro-dosing provides promising results considering crops productivity and farmers' income when used for cerealbased cropping systems in sub-Saharan West Africa (Adams et al, 2016;Tovihoudji et al, 2018). The fertilizer micro-dosing technology utilizes direct application of a small quantity of mineral fertilizer placed at an optimized depth and distance around the target crop either at planting time or a few weeks thereafter (Adams et al, 2016;Tovihoudji et al, 2018).…”

Plant nutrient management can influence the type and level of polyphenolic compounds within leafy vegetables. Therefore, we investigated the effects of fertilizer micro-dosing and harvest time on antioxidant activities of aqueous polyphenolic extracts from Amaranthus cruentus, Ocimum gratissimum and Solanum macrocarpon. Plants were cultivated using urea alone or combined with cattle manure for three staggered harvest periods. Polyphenolics profile (RP-HPLC), DPPH, hydroxyl and superoxide radical scavenging activities, ferric ion reducing power, ferrous ion chelation and inhibition of linoleic acid oxidation were determined. Polyphenolic contents of A. cruentus (caffeic acid, myricetin, quercetin and rutin) and O. gratissimum (catechin and gallic acid) as well as antioxidant activities of the vegetables extracts (except hydroxyl radical scavenging by A. cruentus) were fertilizer micro-dose and harvest timedependent. Thus, combination of both factors highlighted the screening of optimal farming conditions for these vegetables in order to get leaf extracts possessing higher polyphenolic contents and antioxidant activities.
