Abstract
Organic matter is one parameter of soil properties which can be used as an indicator of soil physical quality and environmental sustainability. The objective of this research was to determine the amount of OM being sequestered under coffee plantation based on slope and crop age at the top 30 cm soil. The research took place in Sibarasok Maninjau, Agam Regency, West Sumatra Indonesia, on which the coffee plantation has been started since the Dutch colonial (in 1936). Based on the research conducted, it was found that the SOC content on the top 30 cm soil was quite high, it reached 4.44% to 7.39% while on the top 5 cm was 8.37%-12.58%. After being calculated with the bulk density of the soil, the stock of OM on the top 30 cm soil was 244 to 368 Mg/ha. Slope showed significant difference on the SOM content. The soil was dominated by loam texture with coarse (sand + silt) particles was >76%, therefore, it had high hydraulic conductivity (12.80 cm/h), but low bulk density (0.93 Mg/m3), medium total soil porosity(64.73%), and high aggregate stability (137.81) in average.
