A simple field test is postulated for assessing ease of cultivation. In the proposed test, representative clods are sampled from the field, and place in portable apparatus where they are split between a cone and a ball. The force and movement to split the clod are recorded; average peak force is then plotted against clod deformation at peak force. Some preliminary data have been accumulated and plotted over a range of soil conditions. With sufficient data, areas on the graph can be identified, indicating that the soil is in a suitable or unsuitable condition for cultivation by a given implement.
