Agricultural production in Saemangeum reclaimed land is limited by low organic matter and nutrients content of soil, which lowers crops productivity. One of the best ways to improve soil properties and yield of upland crops are to increase soil organic matter by using organic amendments. To investigate effects of organic amendments on crop productivity and improvement in soil properties, we cultivated maize in an experimental field on Saemangeum reclaimed land with four treatments of compost and chemical fertilizer (FC), chemical fertilizer (F), control (C), and non-cultivation (N). The increments of organic matter (OM), available phosphate, calcium to potassium ratio (Ca/K ratio) was the greatest in FC treatment. Organic matter contents showed an increasing trend with the application of fertilizer and compost to the soil. The organic matter in the FC treatment increased to 6.29 g kg<SUP>-1</SUP>, the highest among the treatments. Available phosphate after the maize harvest was 33 mg kg<SUP>-1</SUP> in the F treatment and was highest in FC treatment, 255 mg kg<SUP>-1</SUP>. The Ca/K ratio in FC and C treatments increased to 4.39 from 2018 to 2020. On the other hand, application of only chemical fertilizer (F) did not affected soil properties. The yield of maize in FC treatment increased by 155% compared with that of control. It was concluded that compost contributed more than only chemical fertilizer in building up the organic matter, phosphorus, and Ca/K ratio status of the soil. Also, Application of chemical fertilizer combined with compost was favorable to increase the content of soil organic matter and available phosphate, and the maize productivity.
