摘要

There are few studies related to no-tillage systems (NT) in coastal tablelands within the Atlantic Forest region, and it is still not known how soil texture influences the establishment of NT on tropical soils. This study evaluated ferralsols with two textures (sandy clay and sandy clay loam) within the Brazilian Atlantic region in relation to straw decomposition and chemical properties after 30, 60, 90, and 120 days of crop cycle. Additionally, soil physical properties (bulk density, macroporosity, microporosity, total porosity, and aggregate stability) were evaluated 120 days after a crop cycle. Soil texture directly influenced the establishment of NT. Throughout the crop cycle and the decrease of precipitation, both straw deposition and nutrient content decreased. The sandy clay soil provided higher nutrient content in the soil and higher C sequestration than the sandy clay loam soil. The sandy clay soil promoted an increase in aggregation, microporosity, and total soil porosity. Our results highlight the importance of soil texture in straw decomposition, nutrients release, and soil physical quality in no-tillage systems in coastal tablelands within the Atlantic Forest. No-tillage systems should be further considered as alternatives in degraded agricultural areas in coastal tablelands in the Atlantic Forest region.
