Soil nutrient deficiency is a problem aftermath of reduction caused by metals and leaching due to low soil organic matter high input synthetic chemical fertilizers. The decline in the corn harvest index decrease fertility. Hence, local materials have urgently needed as Ultisol ameliorant. This study aims determine right combination chicken manure cow produce best increase plant height dry weight, pH, CEC. research has conducted at Hasnur Polytechnic, South Kalimantan, from April 2022 August used completely randomized design with 200 g divided into three combinations P0 (control), P1 (30% versus 70% manure), P2 (50% 50% P3 (70% 30% manure). results showed that treatment increased height, optimal while significant CEC because had varied balanced content compared manure.
