“…Actualizing this will require the need to amend the soil with a biological inert material such as biochar, noted for its nutrient retention characteristics and soil structure stabilization (Lehmann 2007). Biochar is derived from the thermo-degradation of organic materials in an oxygen-depleted environment with physiochemical characteristics that makes it suitable for use as a soil conditioner and carbon sequester (Shackley and Sohi 2010;Bouqbis et al 2016). Studies by Bouqbis et al (2016) and reported that biochar improves soil chemical properties, decreases soil acidity, increases cation exchange capacity (CEC), improves soil aggregates, retains nutrients and helps influence water infiltration dynamics in different soil types.…”

Purpose Biochar and inorganic fertilizer when co-applied have been reported to increase crop yield and enhance soil fertility. However, studies on this complementary effect on soil properties and rain-fed upland rice performance in Sub-Saharan Africa are still scanty. Methods Field factorial studies conducted over 2 years was set up to investigate the interactions between rice husk biochar and inorganic nitrogen (N) fertilizer on a sandy clay loam Alfisol. A two-factor (4 × 4) in RCBD where rice husk biochar was incorporated at four doses, 0, 3, 6, and 12 t/ha −1 , inorganic N fertilizer (urea) at four rates, 0, 30, 60 and 90 N kg/ha −1 , and their combinations was adopted. Results Results showed that combination of biochar and N fertilizer exerted significant (P > 0.05) interactive effect on rice harvest index, grain and straw yield and N-use efficiency. Interaction between biochar and N fertilizer increased agronomic efficiency by 140% and grain nutrient recovery by 191% over 2 years. Combination of biochar and N fertilizer reduced soil bulk density, increased water holding capacity and soil chemical status such as pH, N, P, K, Corg, Ca, ECEC and base saturation, all within the top 10 cm depth of the soil. Conclusions Overall, the results established that rice husk biochar can be used as a soil conditioner to enhance upland rice yield on an Alfisol. The combined dose of 3-6 t/ha −1 biochar and 30 kg/ha −1 of N fertilizer is thus recommended for upland rice farmers in the study area.

“…The contents of iron, manganese copper and zinc were, 0.4, 7.4, 0.9, and 2.6 ppm, respectively. The waste feedstock of banana leaves was pyrolyzed in a Moroccan pyrolysis process heater based on a model by Prof. Claudia Kammann (Bouqbis et al 2016). The detailed physicochemical properties of banana waste biochar have previously been reported (Fetjah et al 2021a).…”

The study's purpose was to reduce the oxidative stress, seasonal physiological changes of paspalum vaginatum and ameliorate soil properties through the addition of banana waste biochar and compost. Different rates of organic amendments were incorporated into sandy loam soil to investigate their impact on paspalum physiological, biochemical, and development in pot and field settings over three seasons (winter, spring and summer). Under the conditions of these two places, paspalum leaves gas exchange characteristics, stomatal traits, anatomy traits, relative water content, proline, antioxidant enzyme activities, and paspalum pigments were determined. For the irrigation system, two rates were chosen: 20% and 60% of the water holding capacity of the control plot WHC. In this study, two advanced statistical analyses were conducted. A factor analysis of mixed data (FAMD) was performed for the analysis of the effect of our charcoal on soil data. Meanwhile, the impact of banana waste biochar on biological activities was investigated using multiple factorial analysis (MFA). The use of biochar and compost blends boosted the cation exchange capacity (CEC) of treated soils, according to our findings. Furthermore, the use of banana waste biochar improved biological basis in the summer season compared with previous seasons. Different antioxidant capacities in seashore paspalum were boosted in the improved soils compared to the untreated ones.

“…The biochar used was prepared from argan shells waste which were combusted in a pyrolytic stove made in Morocco based on the model provided by Dr. Claudia Kammann (Institute for Plant Ecology, Giessen University, Germany) (Bouqbis et al, 2016). The compost from varied vegetable organic matter, bought from commercial vendors in Morocco, was provided with soil by Dr. Harrouni (Hassan II Agronomic and Veterinary Institute (IAV)).…”

The lack of organic matter content in deteriorated soils in drought stricken areas is a serious problem for vegetation cover. The use of organic amendments like biochar and compost to agricultural soils could be a good remedy for poor soil, water deficiency and plants growth. The comparative analysis of the effects of biochar produced from argan shells, compost and their mixture on the growth of quinoa (Chenopodium quinoa), sugar beet (Beta vulgaris) and alfalfa (Medicago sativa) was the main objective of this research. It was assumed that the addition of biochar mixed with compost could enhance soil fertility and then improve crop productivity of plants. For this purpose, three treatments (2%, 4% and 6%) of biochar (B), compost (C) and biochar-compost (B-C) mixture were applied to soil. The samples for different treatments were collected, incubated and then analyzed. In order to evaluate the plant growth, the greenhouse experiments were conducted for three months in the pots filled with untreated and treated soils. The results showed that the addition of biochar and compost to soil increased pH, electrical conductivity, exchangeable cations, total nitrogen, phosphorus, total organic matter and cation exchange capacity. A significant improvement of the biomass of plants has been observed when applying a mixture of biochar and compost at 6% for quinoa and sugar beet and at 4% for alfalfa. According to the obtained results, mixing argan biochar with compost has a positive impact on soil nutrients and growth of plants.
