Extreme Tractor Farm Agriculture & Heavy Equipment Farming

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.

Another interesting development pioneered in France is the robotic approach to harvesting tree fruit like apples and oranges where the mature fruit is selected by machine vision using light reflectance, picked mechanically by the robot and conveyed pneumatically (under vacuum) to a storage pallet. Whether these exciting but expensive technologies can be successfully commercialized remains to be seen. Gantry mechanization (including harvesting) of fruits and vegetables in greenhouses has also been investigated but cost remains a difficult factor to overcome.

The mechanization of farming practices throughout the world has revolutionized food production, enabling it to maintain pace with population growth except in some lessdeveloped countries, most notably in Africa.
Power supply may be considered as autonomous at different levels: at local on-farm level, at local co-operative level or at national level. At local level autonomous power supply may be defined as that power which is generated on-farm for local on-farm use.An example was the mass-produced and low-cost Fordson tractor introduced by Henry Ford in 1916. Soon after the Irish inventor and agricultural engineer, Harry Ferguson, recognized the utility of a greater integration of the tractor with the implements and machines (plows, seeders, agrochemical applicators, harvesters, feeders), which were pulled behind it by a simple drawbar hitch.

Precision seeders place single seeds at predetermined intervals in evenly spaced rows to provide an optimum plant population using pretreated seeds suited to mechanical metering under gravity and with high germination and establishment potential. Plants with lesser germination potential or those requiring an earlier growing date (rice, tomatoes, cabbage, lettuce, tobacco) may be transplanted typically in biodegradable containers in which the seedling has been established in greenhouses.
