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.

Furthermore, workers in greenhouses are employed in a much more comfortable and hospitable environment than field workers and as such the pressure to mechanize is less intense. Looking to the future, harvesting techniques will continue to attract substantial interest and investment in determining if the state-of-the-art technologies (machine vision, robotics, software engineering, GPS and GIS) can be successfully applied to harvesting machines particularly in relation to selective harvesting and the harvesting of delicate produce for the fresh market.

In the early 19th century, animals were the chief source of power in farming. Later in the century, steam power gained in importance. During World War I gasoline- (petrol-) powered tractors became common, and diesel engines later became prevalent. In the developed countries, the number of farm workers has steadily declined in the 20th century, while farm production has increased because of the use of machinery.
The importance of enhancing and upgrading such mechanization practices prior to the almost inevitable transition to engine-driven equipment is now well recognized. Automation of agricultural mechanization is an intensive area of research and development with emphasis on enhancement of food quality, preservation of operator comfort and safety, precision application of agrochemicals, energy conservation and environmental control.Position control is a system whereby the position of a fully mounted implement (sprayer or fertilizer distributor, whose weight is completely supported by the tractor) is automatically maintained in a constant position (e.g. operating height over the ground) despite leakages in the hydraulic system tending to lower the position of the implement.

Likewise, transplantation in areas inaccessible to tractors (rice paddy fields or steep mountain slopes) is possible using aerial power where large areas need to be planted in order to justify the increased cost.
