“…Biochar was analyzed for pH using the glass electrode method and biochar carbon was determined by the loss on ignition protocol by subjecting biochar to relatively high temperature (550 °C) for 4 h ( Mikos-Szymańska et al., 2019 ). Micro Kjeldahl method was followed to analyse for total nitrogen in biochar ( Allen et al., 1974 ) and ammonium phosphomolybdate protocol was used for total phosphorus determination ( Motsara and Roy, 2008 ).…”

The preparation and application of biochar by smallholder farmers is labour intensive hence an effective one-time application for multiple cropping seasons would be desirable by farmers and researchers. In this study, one-time biochar application as a soil amendment and its interaction with compost and NPK on yield performances of different crops was investigated across three cropping seasons. Treatments included biochar applied alone or together with compost, inorganic NPK fertilizer or both. Maize, okra and cassava were planted in succession and data was collected on their shoot N, P and K concentrations, yields as well as selected soil parameters (pH, exchangeable acidity, total exchangeable bases, effective cation exchange capacity, total N, total organic carbon, available phosphorus). Data was analyzed with GenSTAT and results were presented in tables and bar graph. Corn cob biochar applied solely did not significantly improve maize and okra yield in the first and second cropping season but increased yield of cassava significantly at the third cropping season. Yield increased in sole NPK, compost and NPK + compost treatments for all cropping cycles, but yields obtained from these treatments in the presence of biochar were greater than their corresponding treatments without biochar. The study also showed that biochar application together with compost, NPK or both, improved total organic carbon, total nitrogen, available phosphorus, total exchangeable bases, exchangeable acidity, effective cation exchange capacity and pH as well as tissue N, P and K of all crops. Our findings demonstrated that a single application of biochar, particularly in the presence of compost, inorganic NPK fertilizer or both can increase yields across three cropping seasons and improve soil fertility.

“…Electrical conductivity (EC) of biochar was determined using conductivity meter (LF91, Germany). Loss on ignition method was used for biochar carbon and ash determination by respectively heating biochar at 550 °C ( Mikos-Szymańska et al., 2019 ) and 900 °C ( Ascough et al., 2018 ) for 4 h. Total nitrogen in biochar was determined using the micro Kjeldahl method as described by Stewarte et al. (1974) .…”

The effect of biochar alone or co-applied with triple superphosphate on rhizosphere soil characteristics, nodule formation, phytoconstituents and antioxidant property of cowpea ( Vigna uguiculata ) is yet to be adequately examined in sub Saharan Africa. A field experiment was conducted where cowpea ( Vigna unguiculata ) was grown in a tropical sandy loam soil amended with biochar at 1.5 t ha −1 and 2.5 t ha −1 solely or together with inorganic phosphate fertilizer (Triple superphosphate), applied at a rate of 60 kg P ha −1 . At 50% flowering, changes in selected rhizosphere soil properties (pH, total nitrogen, available phosphorus, soil organic carbon, cation exchange capacity), nodule count, phytochemicals (phenols, flavonoids, alkaloids, tannins, saponins) and antioxidant property of cowpea roots and leaves were determined by standard laboratory procedures. Differences between means of the measured parameters were established using ANOVA, and relationships among the parameters were explored using Pearson correlation (p < 0.05). Addition of biochar solely or in combination with TSP significantly (p < 0.05) increased soil pH, total nitrogen, available phosphorus, soil organic carbon, cation exchange capacity and root nodule count. Flavonoids, phenols, alkaloids, saponin, tannin contents and antioxidant activity in the roots and leaves were significantly (p < 0.05) higher in the amended soils compared with the unamended soil. Similarly, soil flavonoids, phenols, alkaloids and antioxidant activity were significantly higher in amended soils compared with control. Significant, positive inter and intra correlation with varying strength was found between soil properties, nodule number and phytoconstituents. This is an indication that biochar can be co-applied with triple superphosphate to sustain soil fertility, improve nodulation and enhance concentrations of phytoconstituents in soil, cowpea roots and leaves.

Wet air oxidation (WAO) of grape pomace, an organic waste generated in massive amounts worldwide and with low biodegradability due to phenol-acid content, was performed to evaluate the potential production of an organomineral fertilizer with biostimulant properties. The synergistic effect of co-processing kimberlite rock powder, a diamond mine tailing, was tested as a potential waste-derived catalyst due to its ferrous iron content and as a potential carbon sink due to its alkaline earth-silicate content. The gaseous, liquid, and solid phases were characterized by gas chromatography, wavelength-dispersive X-ray fluorescence, pH, loss on ignition, thermogravimetric analysis, attenuated total reflectance Fourier-transform infrared spectroscopy, calcimetry, and turbidity, and the results were also subjected to bivariate and multivariate analyses (Pearson correlation coefficient and principal component analysis) to uncover data patterns. The products obtained from WAO were evaluated in bioassays for their soil amendment properties: one assay as a nutrient source to alfalfa (Medicago sativa L) and another assay with soybean (Glycine max L. Merrill) under abiotic stress. The results revealed that temperature and kimberlite play an important role in the oxidation performance of steadfast humic-like substances, and kimberlite is a sink for part of the CO2 that is produced during WAO via mineral carbonation. The WAO products were found to possess beneficial nutrients and properties as soil amendments in terms of sustaining early plant development and alleviating salinity stress.
