Today’s Irrigation

I found this guest lecture by James Adkins especially interesting and educational. I learned a lot from this lecture. James presented to us that irrigation has been around for thousands of years, relating back to the Egyptians using the Nile River to irrigate their crops. He then went on to give an overview of the different types of irrigation practices: surface irrigation, localized irrigation, sprinkler irrigation, and sub irrigation. It was really interesting to see how much thought and science went behind irrigation practices and how monitored and controlled it is. He explained available water holding capacities based on soil types and that the soil types local to our area are mostly sandy loam  which can hold 0.11-0.15 inches of water per inch of soil, which, you can test for this level of moisture with various technologies like the Field Scout. Advancements and research in irrigation practices are so important with the threat of water scarcity and James Adkins reassured us that a lot of thought goes into how much and how often crops get irrigated. He explained the growth cycle of corn and how it requires different levels of moisture throughout its life cycle and how farmers have a rhyme and reason behind how much they irrigate. Irrigation is so important to agricultural production and I look forward to seeing what new technology they come out with next!
