Summary

This study investigates the long-term consequences of contrasting sugarcane harvesting systems on soil health indicators and crop productivity in the tableland soils of Linhares, Espírito Santo, Brazil. It likely compares green (trash blanket/unburnt) harvesting against burnt harvesting, examining effects on soil organic carbon accumulation and micronutrient dynamics — both of which are critical in the typically low-fertility, highly weathered Oxisols and Ultisols characteristic of Brazilian tabuleiros. The findings are expected to contribute evidence on the agronomic and environmental trade-offs of transitioning away from pre-harvest burning in tropical sugarcane systems.

UK applicability

This study is specific to tropical Brazilian sugarcane agroecosystems on highly weathered tableland soils, which have little direct agronomic parallel in the UK. However, the underlying principles regarding harvest residue management, soil organic carbon dynamics, and micronutrient cycling may offer transferable insights for UK practitioners managing crop residues in arable systems.

Key measures

Crop yield (t/ha); soil micronutrient availability (mg/kg or mg/dm³); soil organic carbon (g/kg or %); possibly soil pH and other physicochemical properties

Outcomes reported

The study likely assessed how different long-term sugarcane harvesting practices (e.g. burnt versus green/unburnt harvest) affect crop yield performance, the availability of soil micronutrients, and soil organic carbon levels in tableland soils of Linhares, Espírito Santo, Brazil.
