Sustainable agriculture can be used to achieve food security by continuously producing agriculture while taking safety, soil health, and environmental and economic considerations into account. Reduced agricultural land for agricultural production could stifle the growth of sustainable agriculture. This study made use of biochar, which is made from organic waste and serves to temporarily hold soil nutrients in the root zone of plants. The focus of this research was to find new ways to expand coastal land use by using biochar made from organic waste as a soil amendment for agriculture, particularly vegetable production. The study employed a two-factor design: the first was the size of the biochar material, which was coarse and fine, and the second was the biochar dosage, which included 10, 15 and 20 tons per hectare. Coconut shell waste was used to make the biochar. According to the results, the application of course-sized biochar at a dose of 15 tons per hectare resulted in lateral root distribution. Vegetable root development tended to be reduced when fine biochar was used. We can conclude that one of the solutions for sustainable agricultural production is to use biochar ameliorant materials made from environmentally friendly organic waste.
