Abstract

This research was conducted in the room of Laboratory, Agriculture Faculty , University of North Sumatera, Medan and soil analize in Analitical Laboratory of PT. Socfindo Medan in Maret-Juni 2016. This research used Completly Randomized Factorial Design, with 2 factors. The first factor is organic fertilizer consist of without organic fertilizers (P0), compost of Tithonia (P1), compost of durian’s shell (P2), compost of palm oil fruit bunches waste (P3), chicken manure (P4), compost of Tithonia + chicken manure (P5), compost of durian’s shell + chicken manure (P6), compost of palm oil fruit bunches waste + chicken manure (P7). The second factor is incubation period (I) are one week and two weeks. The result showed that application of organic fertilizer are compost of Tithonia, compost of durian’s shell, compost of palm oil fruit bunches waste, chicken manure, and the mixed compost with chicken manure was significant for  C-Organic, totally soil-N, totally soil-P, and K exchange soil in Ultisol. The period incubation was not significant for C-Organik, totally soil-N, totally soil-P, and  K exchange. The interaction of organic fertilizer application and period of incubation treatments was not significant for all parametric

Abstract

The objective of this study is to determine the effect of some organic matter and incubation period on the pH, C-organic, total-P, total-N and K-exchange on Ultisol. This research conducted in Soil Science Laboratory, Faculty of Agriculture, University of North Sumatra. This study used completely randomized design which consist of two factors with three replications. Factor I: organic matter (B)  ie : B0 (without organic matter), B1 (compost of Tithonia diversifolia 10g/pot), B2 (compost of durian skin 10g/pot), B3 (compost of oil palm empty fruit bunch 10g/pot), B4 (chicken manure 10g/pot), B5 (compost of Tithonia diversifolia 5g/pot + chicken manure 5g/pot), (compost of durian skin 5g/pot + chicken manure 5g/pot), B7 (compost of oil palm empty fruit bunch 5g/pot + chicken manure 5g/pot) and factor II : the incubation period (I), ie : I1 (three weeks incubation), I2 (four weeks incubation). The results showed that application compost of durian skin, Tithonia diversifolia, and compost of oil palm empty fruit bunch significantly increased soil pH, C-organic, total-P, total-N and K-exchange. The combination between compost of durian skin and chicken manure significantly increased Ultisol soil pH. Keywords : Incubation, Organic matter, Total-P, Ultisol
