Early methods of weed control included mowing, flooding, cultivating, smothering, burning, and crop rotation. Though these methods are still important, other means are perhaps more typical today, particularly the use of herbicide (plant-killing) chemicals. Another technique is to introduce insects that attack only the unwanted plant and destroy it while leaving the crop plants unharmed.
The development of the moldboard plow facilitated the inversion and burial of layers of surface vegetation (grass, weeds, cereal stubble), exposing a virgin soil surface which could then be further broken down into a fine seed bed by draft or power driven tined implements. The development of the multi-furrow moldboard plow powered by high-speed tractors underscores the high productivity of modern mechanization systems as compared to the single furrow plow drawn by a slow moving draft animal.
