Precision Farming and Geographic Systems

Global market economy and the growing concern about environment have been moving agricultural production into the area of conflict between economy and ecology. Increased efficiency in agricultural productivity via plant breeding, mechanization, and management techniques have all been important factors in maintaining the balance between food supply and world demand. Necessary improvements in the farmer’s profit were gained by higher yields mainly as a result of higher doses of fertilizer. However, over-fertilization leads to a higher environmental burden. Therefore efforts are necessary to gain a balance between nutrient supply and nutrient uptake.
