The purpose of this study was to determine the effect of biochar and compost fertilizer and their interactions on changes in the physical and chemical properties of soil and corn products on dry land. This experiment uses a randomized block design with factorial patterns. The first factor, the biochar dose consisted of 4 levels, namely: 0; 5; 10; and 15 tons ha − 1. The second factor, compost dosage consisted of 2 levels: 0 tons ha − 1 and 20 tons ha − 1. The highest dry corn seed per ha was obtained from the treatment of 10 tons ha − 1 biochar which was 9.21 tons which increased 35.56% compared to dry corn seeds per ha which were obtained from the treatment without biochar which was 6.79 tons. The treatment of compost doses of 20 tons ha − 1 gave the highest value of dry corn seeds per ha, which was 8.73 tons, an increase of 16.58% compared to the lowest yield, which was 7.49 tons in the treatment without compost. The interaction between the treatment of biochar and compost dosages had no significant effect on all observed variables, except for organic C, available P, available K, and very significant CEC effect.
