Critical limits of soil penetration resistance in a rhodic Eutrudox Rev. Bras. Ciênc. Solo
Moraes,Moacir Tuzzin de; Debiasi,Henrique; Carlesso,Reimar; Franchini,Julio Cezar; Silva,Vanderlei Rodrigues da.
Soil penetration resistance is an important indicator of soil physical quality and the critical limit of 2 MPa has been widely used to characterize the soil physical quality, in both no-tillage and conventional systems. The aim of this study was to quantify the influence of different tillage and cropping systems on the soil penetration resistance in a Rhodic Eutrudox. The experiment was carried out in a 5 × 2 factorial, completely randomized block design (tillage systems vs cropping systems), with four replications. The tillage systems consisted of: conventional tillage disk harrow; minimum tillage with annual chiseling; minimum tillage with chiseling every three years; no-tillage for 11 consecutive years; and no-tillage for 24 consecutive years. The...
