ANALISIS KANDUNGAN BAHAN ORGANIK TANAH DI KEBUN TRADISIONAL DESA SEREH KABUPATEN KEPULAUAN TALAUD

Abstract

ABSTRACT

The objectives of this study were to determine the content of soil organic matter
in traditional gardens in Sereh Village, Lirung District, Talaud Islands Regency. This
research was conducted in the Traditional Garden of Sereh Village and the Laboratory
of Chemistry and Soil Fertility, Faculty of Agriculture, Unsrat for 1 month. This
research uses a survey method. Sampling was carried out using the sampling method
in groups / cluster sampling (CS). Soil samples were taken with a depth of 0-50 cm,
50-100 cm, and> 100 cm under the clove, nutmeg and coconut plants. The chemical
parameters analyzed were; organic matter content (Walkley and Black Method). Soil
samples were analyzed at the Laboratory of Chemistry and Soil Fertility, Department
of Soil, Faculty of Agriculture, Sam Ratulangi University.
Based on the results of the analysis, it shows that the organic matter content is
low to moderate with the details that are in the low category, namely: In the 50-100 cm
layer -and> 100 cm the upper slope of the clove plant is 1.80% -1.20%, the nutmeg
plant is worth 1, 80%, and coconut plants worth 1.92%. The middle slope of the clove
plant was 1.80% -1.20%, the nutmeg plant was 1.20%, and the coconut plant was
1.80%. The lower slope of the clove plant was 1.92% -1.68% -1.56%, the nutmeg plant
was 1.80% -1.20%, and the coconut plant was 1.56%. And in the medium category,
namely: In layers 0-50 cm and 50-100 cm, the upper slope of the clove plant is 3.95%,
the nutmeg is 3.59% -2.99%, and the coconut plant is 3.71% - 2.40%. The middle slope

of the clove plant was 3.59%, the nutmeg plant was 3.95% -3.35%, and the coconut
plant was 2.99% -2.40%. The lower slope of the nutmeg plant is 3.11%, and under the
coconut plant it is 3.95% -2.04%.
