The impact of biochar applications on specific soil fertility parameters

Abstract

Biochar technology is a rapidly growing field of interest within the scientific community due to its multifunctional functions. This study aims to assess the impact of the application of different types of biochar on specific soil fertility parameters. To conduct this study, four different types of plant residues (Vine (Vitis vinifera L.), Tomato (Solanum lycopersicum L.), Banana (Musa), and Carnation (Dianthus caryophyllus. L.)) were used to produce biochar through slow pyrolysis system at 300°C and 500°C. The experiment was designed in randomized complete block with five replications and nine treatments. The treatments included the Control, Vineyard biochar (300°C and 500°C), Tomato biochar (300°C and 500°C), Banana biochar (300°C and 500°C), and Carnation biochar (300°C and 500°C). The trial consisted of a total of 45 pots. Each pot contained 10 kg of soil and 80 g of biochar (equivalent to 20 tons ha−1) strongly mixed and incubated for 300 days. At the end of the incubation period, the biochar treatments were found to improve specific soil fertility parameters (pH, EC, CEC, soil penetration resistance, and bulk density) compared to the control. The use of biochar as a soil enhancer proved to be an effective method for managing soil fertility. This research provides valuable insights into the potential benefits of biochar in sustainable agriculture.
