Tillage systems and their impact on the quality of agricultural soil

Abstract

The objective of the present investigation was to compare the effects of the conservationist and conventional tillage system on the physical and chemical properties of the soil. Two soil samples were taken at different depths from 0 to 5 cm and from 5 to 30 cm. The apparent density (Da), electrical conductivity (EC), pH, cation exchange capacity (CEC), carbonates, organic matter (OM), nitrate (NO3-), available phosphorus and potassium (P and K) and bases were evaluated. interchangeable (Ca 2+ , Mg 2+ , K + y Na + ). It was observed that the conservation tillage system neutralizes the pH, regulates the concentration of exchangeable bases and reduces the concentration of carbonates. The evaluations of the aforementioned parameters allow us to conclude that the conservation agriculture system is an alternative to favor soil quality.
