“…Organic amendment has been known to enhance soil aggregate formation and stability [47]. e increase in soil aggregate stability following biochar application could be due to high carbon (C) associated with biochar [48]. e C molecules form bonds with the oxides, and the organic matter (OM) serves as food for soil microorganism making the environment favourable for them.…”

Among agricultural soil amendment that can enhance crop productivity and soil sustainability is biochar. Hence, two-year field experiments were conducted on a sandy loam Alfisol at Owo, southwest Nigeria, to evaluate the effects of biochar produced from hardwood on soil physical and chemical characteristics, erosion potential, and cocoyam (Xanthosoma sagittifolium (L.) Schott) yield. The study was a 2 × 4 factorial experiment with two years (2017 and 2018) and four biochar levels (0 (control), 10, 20, and 30 t ha−1). The treatments were laid out in a randomized complete block design with three replications. Results indicated that biochar application significantly in both years improved yield of cocoyam and soil physical (bulk density, porosity, moisture content, mean weight diameter (MWD) of soil aggregates, dispersion ratio, and infiltration rate) and chemical (soil organic matter, pH, N, P, K, Ca, Mg, and CEC) properties and erosion resistance. Soil characteristics and cocoyam yield improved with level of biochar from 0–30 t ha−1. When 2018 is compared with 2017 in term of soil loss, in the amended plots, 2018 reduced soil loss by 7.4, 20, and 73.5%, respectively, for 10, 20, and 30 t ha−1biochar, whereas there was an increase of 2.7% soil loss in the control plot in 2018 compared with 2017. Therefore, application rate of 30 t ha−1 biochar is considered as suitable for severely degraded soil because this application rate efficiently improves cocoyam yield and soil properties and reduces soil loss.

“…Thus, organic amendment can possess a global warning (Wu et al, 2018). On the other hand, biochar is a promising organic amendment, which is produced from the pyrolysis under limited oxygen conditions (Alghamdi, 2018). This amendment can shift soil biota towards low C turnover bacteria taxa (Zheng et al, 2018) thus, reduces the emissions of greenhouse gases GHGs (Awad et al, 2018).…”

“…In addition to porosity, the reduction of biochar particle size increases the specific surface area (Kishimoto and Sugiura 1985;Van Zwieten et al 2009) and increases the water retention and AWHC (Duarte et al 2019b, Glab et al 2016. However, these benefits are dependent not only biochar amount but also the time of interaction with the soil as well as biochar particle size (Alghamdi 2018;Blanco-Canqui 2017;Duarte et al 2019b;Glab et al 2016).…”

Biochar is known for its effects on carbon sequestration and soil fertility. However, there is a lack of information about its effects on soil physical and hydraulic properties for tropical soils. We assessed the effects of biochar (BC) plus sugar cane filter cake (FC) rate, and time of interaction on soil physical and hydraulic properties under humid tropical conditions. For this purpose, a field experiment was installed at a loamy sandy soil with five treatments and four replicates: control (only soil), 25 Mg ha −1 sugar cane filter cake, and 25 Mg ha −1 sugar cane filter cake plus 6.25, 12.5, and 25 Mg ha −1 Miscanthus biochar, respectively, two soil depths (0-10 and 10-20 cm) and two times of interaction (9 and 18 months). Physical properties (aggregate stability, bulk density, total porosity, pores size distribution) and hydraulic properties (soil water holding capacity, hydraulic conductivity, plant-available water holding capacity) were measured after nine and eighteen months. The bulk density decreased slightly, and the porosity increased after nine months, for the biochar plus sugar cane filter cake (both 25 Mg ha −1). After 18 months, biochar plus filter cake interaction increase micropores, aggregate stability, and plant-available water content. Saturated hydraulic conductivity was not influenced by sugar cane filter cake. However, biochar significantly reduced saturated hydraulic conductivity when combined with sugar cane filter cake after 18 months. We concluded that sugar cane filter cake in combination with biochar modified the pore size distribution, slightly increased plant-available water holding capacity, and significantly decreased saturated hydraulic conductivity.
