The soil conservation in agriculture may contribute to productivity and sustainable production. The objective was to measure the mass loss rate of cellulose decomposition process in agriculture systems, in different cultivation times (more than 30 years vs. less than 10 years) considering forest in conservation unit and close anthropic forest as control systems. We used substrate bags of two mesh sizes (0.5 mm vs. 10 mm) in soil surface for 30, 60 and 90 days in all systems (agriculture systems vs. close anthropic forest and forest in conservation unit). Cellulose decomposition ecosystem service decreased by a quarter (effect size range ± -22 to -26%) in the studied agriculture systems compared to forests systems, highlighting the cotton strip breakdown process as a good ecological indicator. High species richness and plant strata in forest systems increase the mass loss compared to agriculture systems. The difference between 10 and 30 year of agriculture systems ranges from 3% (total decomposition) to 7% (microbial decomposition), lower in 30-year systems. Also, forest fragments near agriculture systems are refuge for detritivore macrofauna and may retain the ecosystem service on these productive areas.
