This study aims to determine the status of soil quality after biochar treatment, compost, and phonska in the cornfield. Soil samples were taken from 48 experimental plots after harvesting of maize. Assessment of soil quality is done by collecting selected indicator data including soil physical and chemical properties to observe changes in soil due to land use and agricultural cultivation practices. The soil quality status in this study was determined by calculating the value of soil quality rating (SQR) based on the weighting of 11 indicators of soil quality. The results showed that soil quality before the research was bad (SQR 30) and improved to moderate (SQR 27) until a good (SQR 20) after the research of biochar, compost and NPK phonska on the cornfield. Improved soil quality in biochar formulations 10.52 t ha-1, compost, and phonska, due to improved soil physical properties such as porosity, bulk density, and soil moisture content, which has encouraged the process of exchange and chemical reactions in the soil to release nutrients for the plant. Giving of bamboo biochar, compost, and NPK phonska on dry land cultivated maize has resulted in good soil quality (SQR 20) or approaching sustainability status is very good (highly sustainable).
