Our guest lecture James Atkins came in and spoke about irrigation. He explained to us the different types of irrigation used on farms today. These included the traveling gun, drip, subsurface, and center pivot irrigation. With the center pivot system being the most popular use of irrigation there are other technologies that have been developed for it to increase its efficiency such as Zone and Variability controlling. This controls each water nozzle on the system. With electro-conductivity mapping, you are shown how over or under watered an area of the field is. With the combination of these technologies you are working the most efficiently, being able to change the amount of water coming out of the nozzle so each area of your field is  getting what it needs and increasing its yield.
