Comparison between incorporation and stubble burning in an Humic Haploxerands Soil, Central Southern, Chile

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 incorporation of crop residue improve soil quality. The objective research was compare effects oat stubble on chemical physical properties an Humic Haploxerands with rotation oat-wheat. A completely randomized experimental design by two treatments sampling at depths 0-5, 5-10 10-20cm, three replicates. results showed that represents sustainable management ash volcanic soils, pH, organic matter , potassium exchangeable aggregates stability porosity.
