Abstract

Biochar, a carbonaceous material prepared from diverse organic waste, has gained substantial attention due to its excellent attributes, like carbon content, CEC, abundant specific surface area, structural characteristics, plant nutrient contribution, water and plant nutrient retention etc. Incorporating biochar to the soil system introduces supplementary organic matter, thereby augmenting the comprehensive nutrient composition and microbial dynamics within the soil ecosystem for a long time that completely fit for perennial crops cultivated in acid prone areas like coffee production. Biochar producing organic materials are easily accessible in coffee production areas from coffee husks that pollute the river streams and generally create environmental pollution. However, as biochar advantages are too aged technology to solve general soil fertility problems, there is no comprehensive research recommendation generated for biochar application in coffee producing area specially in organic coffee producing countries like Ethiopia. Therefore, this systematic review attempts to gather more available empirical research on google scholars by using clearly defined, systematic terms to obtain answers for a specific question like ‘how to use biochar for coffee production and coffee nursery media preparations. More than 70 papers written by different authors and project papers were searched from google scholars and research gets. Through this investigation, we obtained critical information that may suggest the sustainable effects of biochar on enhancing soil fertility and improving both the production and productivity of coffee, while simultaneously preserving the ecological integrity of the soil system. Applying biochar for soil fertility enhancement is a critical technic that boosts the soil physical, chemical, and biological contents while mitigating the greenhouse gas like methane emission and sequestering the carbon stalk within the soil systems.
