“…It is commonly reported that biochar benefits are related to an increase of CEC, sorption capacity, contribution of nutrients and creating a favourable environment for microbial growing (Blanco-Canqui, 2017). A decrease of aluminum toxicity induced by biochar application could increase soil pH and the concentrations of soil available nutrients, resulting in increased plant growth in several studies (Jha et al, 2016; Lin et al, 2018; Qian, Chen & Hu, 2013). In the current study, overall biochar application increased the concentrations of soil AP, AN and AK, thus benefiting plant nutrient uptake.…”

IntroductionRice bean (Phaseolus calcaltus), as an annual summer legume, is always subjected to acid soils in tropical to subtropical regions, limiting its growth and nodulation. However, little is known about its responses to lime and biochar addition, the two in improving soil fertility in acid soils.Materials and MethodsIn the current study, a pot experiment was conducted using rice bean on a sandy yellow soil (Orthic Acrisol) with a pH of 5.5. The experiment included three lime rates (0, 0.75 and 1.5 g kg−1) and three biochar rates (0, 5 and 10 g kg−1). The biochar was produced from aboveground parts of Solanum tuberosum using a home-made device with temperature of pyrolysis about 500 °C.Results and DiscussionThe results indicated that both lime and biochar could reduce soil exchange Al concentration, increase soil pH and the contents of soil microbial biomass carbon and microbial biomass nitrogen, and enhance urease and dehydrogenase activities, benefiting P. calcaltus growth and nodulation in acid soils. Lime application did decrease the concentrations of soil available phosphorus (AP) and alkali dispelled nitrogen (AN), whereas biochar application increased the concentrations of soil AP, AN and available potassium (AK). However, sole biochar application could not achieve as much yield increase as lime application did. High lime rate (1.5 g lime kg−1) incorporated with low biochar rate (5 g biochar kg−1) could obtain higher shoot biomass, nutrient uptake, and nodule number when compared with high lime rate and high biochar rate.ConclusionLime incorporated with biochar application could achieve optimum improvement for P. calcaltus growing in acid soils when compared with sole lime or biochar addition.

“…Thus, biochar may act as both a source and sink of nutrients that are required for plant growth, and it can be strongly recommended for weathered poorly fertile soils for improving the nutrient retention and crop productivity. Apart from improving CEC, biochar could also improve the retention ability of Ca 2+ , Mg 2+ , K + and NH4 + ions in acidic soil (Alfisol) (Jha et al, 2016). However, most of the reports studying the effect of biochar on soil pH and CEC are laboratory based short-term experiments, with very few long-term field studies (Wang et al, 2021).…”

“…pH was found to increase gradually with increase in application rate of biochar [41]. The soil acidity ameliorating effect of Leucaena biochar was investigated in an incubation study in an acid soil (pH = 4.5) in northwest India by Jha et al [45] and it was reported that the mean increase in soil pH was 0.65, 1.35, and 2 units at 2 per cent, 4 per cent, and 6 per cent (w/w) of biochar incorporation respectively.…”

Biochar refers to the black carbon that is produced by the process of slow pyrolysis and act as a vehicle of carbon sequestration from renewable and sustainable biomass. This review describes the ability of biochar to improve the physical, chemical and biological properties of soil and thus increase crop yield and productivity. Benefits of application of biochar also includes lowering of bulk density, improving porosity, aggregation, water infiltration and water holding capacity of soils. It also darkens the soil colour which affects soil surface reflectance and thus helps to moderate soil temperature. Biochar addition enhances cation exchange capacity, increases soil pH, improves the supply and uptake of nutrients, reduces nutrient leaching losses, captures NH3 and leads to reduction in volatilization loss of nitrogen thus improving nutrient availability in soils. Application of biochar can also remediate soils contaminated with heavy metals and organic pollutants. It can also facilitate microbial colonisation in soil, enhance soil microbial biomass carbon, enzyme activity and the activity of mycorrhizal fungi.
