Major crop nutrient fertilizers (nitrogen, phosphorus and potassium (NPK)) are typically applied in powdered (small particles), granular (larger particles) or in liquid form either as individual or as compound fertilizers. The fertilizer may be applied using a combine (corn) drill where the seed is contained in one hopper and dry fertilizer in another behind it.

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.
