Opis:
Residue incorporation is not a common practice in many production systems in areas with a Mediterranean climate. The aim of the research was to study the effect of residue incorporation levels of three cycles of two biannual rotations on corn yield and chemical properties of soil after six years. An experiment was conducted with two biannual rotations (canola-corn and bean-corn) and four residue incorporation levels (0%, 50%, 100%, and 200%) in a Chilean Andisol (Melanoxerand). Corn grain yield and residue production were evaluated during three cycles of crop rotation, and the soil’s chemical properties were evaluated at the end of the evaluation round. The experimental design was a split plot, in which the main plot was the previous crop (two crops) and the split plot was the residue level (four levels). The results showed that the highest corn grain yield was obtained in the first evaluation season (p<0.05), when the average yield for both rotations was 10.1% higher than the average yield obtained in the third season. On the other hand, the average residue production of the first two seasons was 15.2% higher than that obtained in the third season (p<0.05). Chemical properties of the soil were affected by a rotation, with an increase in pH in the bean-corn rotation after bean cultivation, and an increase in both exchangeable Al and available S in the canola-corn and bean-corn rotations after canola. On the other hand, the use of increasing doses of residue enabled a consistent increase in the content of both organic matter and exchangeable K in the soil, and partially the available P in soil. The concentration of exchangeable Ca was increased with an increasing dose of residue only in the rotation with canola. Finally, this work allows us to conclude that continuous incorporation of the residues produced within the biannual rotations evaluated in this volcanic soil contributes to improvement of the soil’s chemical properties, without affecting the corn crop yield.
