Abstract

Soil organic C (SOC) play a crucial role in sustaining soil health and mitigating climate change. However, depletion of SOC pools in the tropics is quite high, therefore, it needs to implement best management practices to reduce it. The objective of this study was to determine five years effects of no-tillage system and bagasse mulching on soil carbon storage and sequestration in sugarcane plantation.The experiment was conducted in 2010-2015, at sugarcane plantation in Sumatra, Indonesia. The experiment was a factorial, split plot design, with 5 replications.Soil tillage system as main plot wasconventional tillage (CT) and no-tillage(NT), while bagasse mulch as sub-plot was80 Mg C/ha/year(M1), and with no bagasse mulch (M0). It revealed thatafter 5 years of tillage and bagasse mulching application, soil C storage under NTM1 was 42,85Mg C/ha or 45.1% higher (P<0.5) than CTM0. Soil C storage under CTM0 was 29.40 Mg C/ha,the lowest among treatment combinations. Soil C sequestration under NTM1 was the highest among treatments (P<0.05), that was 2.75 Mg C/ha/year, while under CTMO was the lowest (0.24 Mg C/ha/year).
