Long-Term Trial of Tillage Systems for Sugarcane: Effect on Topsoil Hydrophysical Attributes

Seeking to provide essential information about sustainable tillage systems, this work aimed assess the effects of liming and soil cultivation systems on hydrophysical attributes a long-term cultivated sugarcane field in tropical region southeast Brazil. Infiltration tests sampling down 0.10 m were performed order determine saturated hydraulic conductivity, bulk density, total porosity, macroporosity, microporosity, resistance penetration. The studied areas include no-tillage (NT) conventional (CT) with 0 (CT0 NT0) 4 (CT4 NT4) Mg ha?1 lime, an adjoining area native forest (NF). data analysis included variance followed by Tukey test compare different assessment Pearson correlation coefficient between variables, principal component dataset. lowest density highest macroporosity conductivity found NF. CT4 NT0 was higher than other indicating need for amelioration. NT4 is suggested as most viable system conservation agriculture fields, combining benefits enhance functions.
