Abstract
Oxisols is a heavily weathered soil that has good physical properties for planting perennial species, such as coffee and pepper. However, this soil has low nutrient availability. Way Kanan District in Lampung Province is one of the central of coffee and pepper productions in Indonesia. In this area, the soil type is dominated by Oxisols. Use of compost made from shells of Arabica coffee fruits is one way to improve soil fertility of Oxisols. The study aimed at understanding the effects of application of compost made from shells of coffee fruits to the chemical properties of Oxisols, i.e. pH, organic C content, total N, available P, and exchangeable-Ca, -K, and -Mg. An incubation experiment was conducted using a completely randomized design with four treatments and three replicates. The treatments were dosages of compost made from shells of coffee fruits i.e. 0, 5, 10, and 20 ton ha-1. Each treatment was incubated during 5, 10, and 15 weeks. The results showed that application of compost made from shells of coffee fruits did not increase organic C content, total N, and available P of Oxisols during different incubation periods (i.e. after 5, 10, and 15 weeks). However, application of the compost significantly increased pH and exchangeable-K, -Ca, and –Mg of Oxisols (P>0.05). The highest pH and exchangeable-K, -Ca, and –Mg were found after application 20 ton ha-1 of compost after 5, 10, and 15 weeks of incubations. The results suggest that application of compost made from shells of Arabica coffee fruits is a potential alternative to improve fertility of Oxisols.
