Chisel ploughs, through the process of deep tillage and soil shattering, contribute to an increase in the mobility of nutrients, particularly nitrogen (N) and potassium (K). The physical disruption of compacted soil layers by the chisel plough allows for improved movement and accessibility of nutrients like nitrogen within the soil profile. As a result, crops cultivated with the assistance of a chisel plough can benefit from enhanced nitrogen availability, promoting better nutrient uptake and utilization by plants.
