- ... Tillage practices profoundly affect soil physical and hydraulic properties. It is essential to select a tillage practice that sustains the soil physical properties required for successful growth of agricultural crops. We evaluated the effects of conventional (CT) and strip (ST) tillage practices on bulk density (rho(b)), gravimetric water content (theta(w)), and saturated hydraulic conductivity (K ...

- ... We evaluated the effect of long-term (>20 years) tillage (no-till [NT], spring till [ST], and fall and spring till [FST]) under continuous spring wheat on soil penetration resistance (PR), bulk density (ρb), water content (θm) and saturated hydraulic conductivity (Ks) under dryland cropping systems. Soil PR was significantly greater in the NT than in ST and FST treatments at 0–10 cm depth, but was ...
