Biochars, produced from different feedstocks, modify soils differently which in turn affect the growth of plants. To this end, comparing the characteristics of oak wood and bamboo biochars, evaluating their effect on soil properties and growth of ryegass (Lolium perenne L.) is crucial. Oak wood (WB) and bamboo biochars (BB) were used to fill pot with soil with 0.5, 1.0 and 2% levels each and control (0%) as treatment. After one week of incubation, rye grass seeds were sown in each pot and allowed to grow for 120 days in a climate controlled glass house. Characteristics of WB and BB, the amended soil quality, the shoots and roots biomass, and nutrient uptake of rye grass were measured and analyzed. Application of WB and BB increased nutrient content, organic C, soil pH, cation exchange capacity (CEC), water holding capacity (WHC), but decreased bulk density (BD) of the soil. As compared to BB, the WB had higher surface properties such as surface area, pore volume and oxygen containing functional groups which modified the soil pH, CEC, BD, WHC, and microbial biomass C of the amended soils. The BB had higher ash content and nutritional properties, thus it increased shoot and root biomass, and the uptake of nutrients in ryegrass. Due to its innate nutrient, BB enhanced plant growth more than WB. While WB improved the soil quality as it had better surface properties than BB. It is suggested that the biochar’s properties contribute in determining soil productivity.

Abstract

Biochars, produced from different feedstocks, modify soils differently which in turn affect the growth of plants. To this end, comparing the characteristics of oak wood and bamboo biochars, evaluating their effect on soil properties and growth of ryegass (Lolium perenne L.) is crucial. Oak wood (WB) and bamboo biochars (BB) were used to fill pot with soil with 0.5, 1.0 and 2% levels each and control (0%) as treatment. After one week of incubation, rye grass seeds were sown in each pot and allowed to grow for 120 days in a climate controlled glass house. Characteristics of WB and BB, the amended soil quality, the shoots and roots biomass, and nutrient uptake of rye grass were measured and analyzed. Application of WB and BB increased nutrient content, organic C, soil pH, cation exchange capacity (CEC), water holding capacity (WHC), but decreased bulk density (BD) of the soil. As compared to BB, the WB had higher surface properties such as surface area, pore volume and oxygen containing functional groups which modified the soil pH, CEC, BD, WHC, and microbial biomass C of the amended soils. The BB had higher ash content and nutritional properties, thus it increased shoot and root biomass, and the uptake of nutrients in ryegrass. Due to its innate nutrient, BB enhanced plant growth more than WB. While WB improved the soil quality as it had better surface properties than BB. It is suggested that the biochar’s properties contribute in determining soil productivity.
