Tillage systems and their impact on the quality of agricultural soil
El objetivo de la presente investigación fue comparar los efectos del sistema de
labranza conservacionista y convencional sobre las propiedades físicas y
químicas del suelo. Se realizaron dos muestreos de suelo a diferentes
profundidades de 0 a 5 cm y de 5 a 30 cm. Se evaluó la densidad aparente
(Da), conductividad eléctrica (CE), pH, capacidad de intercambio catiónico
(CIC), carbonatos, materia orgánica (MO), nitrato (NO 3 - ), fósforo y potasio
disponible (P y K) y bases intercambiables (Ca 2+ , Mg 2+ , K + y Na + ). Se observó
que el sistema de labranza conservacionista neutraliza el pH, regula la
concentración de bases intercambiables y reduce la concentración de
carbonatos. Las evaluaciones de los parámetros antes mencionados permiten
concluir que el sistema de agricultura de conservación es una alternativa para
favorecer la calidad del suelo.

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 (Ca2+, Mg2+, 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.
