Interpretive Summary:

Technical Abstract: A field study was carried out from 2013 to 2019 to investigate the effect of no-till (NT) and conventional tillage (CT) on soil cone index (CI) in a 2-yr corn (Zea mays L.)-soybean (Glycine max [L.]) rotation on a Lihen sandy loam. The study was arranged in a randomized complete block design with five replications. Soil CI was measured with a digital penetrometer to a depth of 0 - 30-cm after planting in crop rows within each plot. Soil CI was significantly impacted by tillage in the 0 - 30 cm depth for the period of the study under both corn and soybean. Averaged across 0 - 30 cm, soil CI values were significantly smaller in CT compared with NT in all 7 years. Soil CI averaged across 0 - 30 cm depth and 7 years resulted in higher CI of 2.027 and 2.030 MPa for NT compared to 1.118 and 1.137 MPa for CT under corn and soybean, respectively. Lower CI values in CT under both corn and soybean may be related to soil disturbance caused by intensive tilling compared to NT management practices.
