Abstract: © 2024, Asociacion Argentina de la Ciencia del Suelo. All rights reserved.This research aimed to evaluate the changes in the soil chemical attributes and their effects on the agronomic attributes of corn, after conversion from conventional tillage (PC) to no-tillage (SD), in a Inceptisol soil (Cambissolo Húmico alumínico léptico). In an experiment where PC and SD effects had been studied for 20 yr, main plots under PC were converted to SD and referred to as implemented SD (SDi) while plots under SD remained unaltered and were referred to as consolidated NT (SDc). The pH in water, exchangeable aluminum, potassium, calcium, and magnesium, extractable phosphorus, and total organic carbon (COT), were determined at the beginning of the experiment and after a 30-month period. The agronomic attributes of corn grown under SDi and SDc were also evaluated. At the end of the experiment, plots under SDi evidenced an increase in exchangeable aluminum and potassium and COT, and a decrease in pH and exchangeable calcium. Corn biomass accumulation in shoots and roots increased and higher grain yields were observed under SDc compared to SDi.
