Characterization of the effects of cultural treatments (half ploughing, normal ploughing and direct drilling) on soil mechanics using the penetrometer (cone index)


, : Characterization of the effects of cultural treatments (half ploughing, normal ploughing and direct drilling) on soil mechanics using the penetrometer (cone index). Proceedings of the 9th Conference of the Soil Tillage Research Organization: 429-435

This study evaluated the mechanical resistance offered by a silt loam soil to a penetrometer (cone index) under normal ploughing to 30 cm, half ploughing to 15 cm, and direct drilling. Measurements were taken five times between June 1979 and November 1980. Measurements show a significantly higher resistance at 10-15 cm depth for direct drilling than for other treatments; and a higher resistance (not significant) at 20-25 cm for half ploughing.
