Stubble burning in Chile is a common practice used for the farmers but it causes nutrient losses , erosion and environmental pollution. An alternative to change this situation is the incorporation of crop residue to improve the soil quality. The objective of this research was to compare the effects of the incorporation of oat stubble and stubble burning on the chemical and physical properties in an Humic Haploxerands soil with crop rotation oat-wheat. A completely randomized experimental design was used by two treatments of incorporation and stubble burning with soil sampling at depths of 0-5, 5-10 and 10-20cm, with three replicates. The results showed that stubble incorporationrepresents an sustainable management alternative for the ash volcanic soils, that improve the soil pH, organic matter , potassium exchangeable , aggregates stability and soil porosity.
