In organic farming the natural basic variation affects more the output of the system than in conventional farming. The conventional farming system uses substantial amount of inputs such as chemicals and energy. Thus the relative share of inputs added to the system is much higher than in organic farming. The inner variability of inputs is also smaller in conventional farming than in organic. The conventional inputs also tend to be easier to control. As a result there is a lower and more variable output in organic farming than in conventional one. In Precision Organic Farming there are many more risks that could make the system uncontrollable. This is mainly because there are some forbidden inputs such as most of the pesticides and insecticides and the level of added inputs is low.

In conclusion, Precision Organic Farming operates with the same basic principles as conventional precision farming. Main differences are in the control targets, controllability of them and the measurement systems needed. Controllability issues may be the most challenging part of the application. The development of on-line measurement of fertility, chemical content, etc. might make Precision Organic Farming more feasible in the future.
