PRECISION AGRICULTURE: KEY CONCEPTS.

The sustainable use of natural resources by employing technical and social modernization of agriculture, is a constant preoccupation, given current challenges related to climate changes, maintenance of competitiveness for agricultural producers and the decrease of dependence to non-renewable resources. In a situation where the world population is constantly growing and the agricultural fund is limited and with clear trends of deterioration, agricultural research has played a particularly important role in increasing production and in the most rational exploitation of existing resources. The concept of precision agriculture involves regulating the inputs to the agricultural system (seeds, fertilizers, pesticides) so that they are distributed in precise location, quantity, and time needed. Measuring the various working parameters through sensors and transducers, analyzing the information received through computer systems and specific software, and sending commands to change other parameters on tractors and agricultural machines created the Smart farming system.
