Background: Amelioration is the technique of adding amendments to sub-optimal drylands to improve their chemical quality. The effectiveness of this amendment depends on the type and dosage of the amendment. Methods: This pot experiment was carried out using a randomized block design (RBD) in 3 replications. Treatment of amendment materials (A) which consists of 8 (eight) treatments, namely: A0 (no amendment); A1 (biochar 20 t ha-1); A2 (compost 20 t ha-1); A3 (CaCO3 4 t ha-1); A4 (SP-36 fertilizer 4 t ha-1); A5 (biochar 10 t ha-1 + CaCO3 4 t ha-1); A6 (compost 10 t ha-1 + CaCO3 4 t ha-1); and A7 (biochar 10 t ha-1 + compost 10 t ha-1). The top soils (0-20 cm) were used in the experiment taken from three soil orders of sub-optimal dryland of Aceh Besar Regency, Aceh (Indonesia), including Andisols, Inceptisols and Ultisols. Result: Providing amendments affects several soil chemical parameters in the drylands of Aceh and this effect depends on the type of ameliorant material and the dose applied as well as the soil order. By applying amendments, soils with a slightly acidic pH could turn slightly alkaline, resulting in an increase in available P, K and cation exchange capacity (CEC) of dryland soils.
