Our class had guest speaker James Adkins speak to us about irrigation systems not only here in the United States, but around the world. I found it very interesting how he went back to how irrigation systems first started and the different types and ways that they are used around the globe. Furthermore, Adkins discussed water use and the different water levels in the ground. This was very intriguing in regards to Delaware agriculture. On my home farm we do not have to use irrigation due to our soil type, whereas, other areas may not have as good of soil. Additionally, I was not aware on the amount of areas that rely solely on ground water which over time may run out. I was not aware that corn requires 22 inches per year of water in order to grow properly, it was something that had never crossed my mind even on our home farm where we grow corn.
