On Friday the 25th April the first year students of Agricultural Production made a visit to the Can Feliu farm, in Campllong. The person in charge, Mr. Xavier Codina, explained to the students the different irrigation systems used for the production of forage intended for feeding the dairy cows. Can Feliu irrigates 120 hectares where they produce a double annual cropping of either ryegrass or barley, and corn. The irrigation systems used are: Center pivot, traveller, solid set, and drip irrigation. Mr. Xavier Codina showed how to use the technology applied to irrigation systems for control and optimization of water use. Another important aspect is the direct sowing of corn after a precision work to uncompactate the soil. Other examples are the use of GPS to the workings of the crops: planting, fertilization, irrigation, and harvesting. Students with this visit have found that the innovation and continuous evolution of agriculture make us to live the reality so called precision agriculture. From school, we thank to Can Feliu and Mr. Xavier Codina their kindness and time that has enabled us to experience this interesting visit.
