A field research study was conducted at the Lancaster Agricultural Research Station in 2004 and 2005 to examine the relationship between tillage treatment and response to K fertilization. The purpose of the study was to evaluate the effectiveness of low disturbance, high residue tillage systems for first-year corn after soybean on erodible soils. Data collected and analyzed to date did not show a significant response to tillage or K fertilization with respect to corn silage or grain yield. Early growth tended to be greater in the strip-till and no-till systems, compared to fall chisel or spring field cultivator. There was a trend for an early season growth response where K fertilizer was applied in the row, compared to surface broadcasting or surface banding. Measured soil loss was greater in the chisel system compared to the strip-till system, especially in 2004 when heavy early-season rains occurred. Results from this research demonstrate that no-till and strip-till systems performed similarly to conventional tillage and resulted in much lower soil loss.
