The invention relates to the technical field of agricultural intelligent irrigation, and provides a soil plowing detection and judgment method. The method comprises the following steps: acquiring the volumetric water content of farmland soil with a preset depth in the irritation process, recording the acquisition time, determining the effective time quantum from irritation beginning to the change of the volumetric water content of the farmland soil according to the volumetric water content of the farmland soil and the acquisition time, and judging that soil plowing is needed if the effective time quantum is longer than a threshold time; and calculating the water seepage speed of the farmland soil in the predetermined time quantum after the change of the volumetric water content of the farmland soil if the effective time quantum does not exceed the threshold time, obtaining the compactness of the soil according to a relationship between the known water seepage speed and the compactness of the soil, and judging
