![]() Plant productivity and above-ground biomass were reduced in 1% BPB treatments, but increased in 2 and 3% BPB treatments as compared to control but statistically insignificant (p < 0.05). Seeds of Cucurbita moschata were sown and 40 days after seed sowing, K deficiency was observed in control treatments.īanana peel biochar was found to be rich in K content. Another pot experiment was also conducted under sand medium to test the BPB as K-rich soil amendment where K was applied from two different sources (KCl and BPB) along with control. ![]() Plants were harvested after 42 days from seeds sowing and plant height, leaf number, fresh weight, and dry weight were measured. After incorporation of BPB into soil, pots were kept under field condition for 7 days and then the seeds of Ipomoea aquatica were sown. Three lower rates (1, 2 and 3%) of banana peel biochar (BPB) were added with agricultural soil along with control with three replications for each. ![]() To understand the sustainable benefits of biochar, two pot experiments were conducted under net house condition in Khulna University, Bangladesh.īiochar was prepared from banana peel waste through slow pyrolysis process under limited oxygen condition. Biochar addition to soil is immensely beneficial for increasing plant productivity and C sequestration, attenuating nutrient leaching loss, counteracting heavy metal contamination and organic waste triggered environmental pollution.
