Have you ever looked out of an airplane window and noticed big green circles in fields below? Those are created by something called center pivot irrigation systems. Let’s dive into what these systems are and how they work.
Center pivot irrigation systems are tools that farmers use to water their crops. They help transfer groundwater to fields, especially when there isn’t enough rain. These systems are crucial for ensuring that crops get the water they need to grow.
When you see these systems from the ground, they look like large bridges or cranes lying on their sides. The main part of the system is a long pipe that rotates around a central pivot point, spreading water across the field. But how does it all come together?
The first step in building a pivot system is to pour a concrete pad for the pivot point. Then, ditches are dug to lay pipes that will carry water to the pivot. It’s a team effort, often involving family members and experts in irrigation systems.
Once the groundwork is done, the assembly begins. The central structure is put together first, followed by an electronics box that controls the system. This box helps manage the movement and water flow of the pivot.
Next, rods are assembled to support the pivot arm, and pipes are organized along with structural supports. Electrical wires are attached, and plastic tubes are connected for the sprinklers. These sprinklers are designed to break off in a storm to prevent damage to the main pipe.
The sprinklers are spaced in a way that ensures even water distribution. As the pivot moves, the farthest tower controls the others, keeping everything aligned. This clever engineering allows the system to water crops efficiently without harming them.
Once the system is up and running, it makes a big difference in crop yields. By comparing irrigated and non-irrigated sections of a field, farmers can see how much more productive their land can be with proper irrigation.
Farmers are truly experts in many areas, including technology and water management. Their work is vital in providing food for everyone, and innovations like center pivot irrigation systems are a big part of that.
I hope you found this exploration of irrigation pivots interesting. It’s amazing to see how technology helps farmers grow the food we eat. If you want to learn more about farming and technology, there are many resources available to explore further!
Using materials like straws, cardboard, and small plastic tubes, build a model of a center pivot irrigation system. This hands-on activity will help you understand how the system rotates and distributes water across a field. Pay attention to the central pivot point and how the arms extend from it.
Imagine you are a farmer with a new field to irrigate. Draw a plan showing how you would set up a center pivot irrigation system to ensure even water distribution. Consider factors like field size and shape, and explain your choices in a short paragraph.
Research another type of irrigation system used in agriculture. Prepare a short presentation comparing it to center pivot irrigation systems. Highlight the advantages and disadvantages of each system and discuss which might be more suitable for different types of crops or climates.
Using hypothetical data, calculate the efficiency of a center pivot irrigation system. Determine how much water is used versus how much reaches the crops. Discuss ways to improve efficiency and reduce water waste in irrigation practices.
Conduct an interview with a local farmer or an expert in irrigation systems. Prepare questions about their experiences with center pivot irrigation, the challenges they face, and the benefits they observe. Share your findings with the class to gain real-world insights into the importance of irrigation technology.

If you’ve ever been flying in an airplane and you look out the window, you might see big green circles in the middle of a field. What are those? Today, we’re going to explore that. This is my buddy Trey; he’s a farmer. Farmers are incredibly knowledgeable, as we established in our last video about grain bins. Today, I have a question: What are those big structures I see in the fields?
They’re called center pivot irrigation systems. It’s a tool we use to transfer groundwater to the fields and apply it to the crops when they need it. If we don’t get enough rain from Mother Nature, we can turn on the pivots and provide the crops with the water they need. We’re building two pivots today, one in this field and one in another.
As we get started, I see these structures while driving around. They look like large bridges or cranes lying on their sides. This is our field, and we’re going to use a pipe to distribute water. The pivot point allows the pipe to rotate, and there are many questions about how it all works. For example, when the pipe fills with water, it gets heavy and wants to sag. How do we support it? Are there different sections, or is it just one long pipe? What do the sprinklers look like? How does it move without damaging the crops?
These questions became clearer as we began building. The first step was pouring a pad for the pivot. Then, we spent time digging ditches to run the pipe out to the pivot point. This was a family effort, with Trey involving his whole family. My initial job was to lubricate the pipes and connect them while Trey’s brother used a track hoe to dig the ditch. We also ran electrical wire alongside the pipe to power the pivot.
A few weeks later, a crew arrived to help assemble the pivots. They were experts in building irrigation systems. I was eager to help, but they advised me to stay out of the way initially. As I learned more, I was allowed to take on more tasks. We laid out the parts for the first of three sections of the pivot and assembled the central structure.
Next, we put together an electronics box that would control the pivot and attached it to the central structure. Then, we began assembling the rods that would support the pivot arm. I learned that there are specific tasks to master, and repetition is key.
As we organized the pipes and structural supports, we also attached electrical wires and connected plastic tubes for the sprinklers. I discovered that the design allows for the sprinklers to break off in case of a storm, preventing damage to the main pipe.
I noticed that the pipe has different configurations for the sprinklers, which helps ensure even water distribution across the field. The sprinklers are spaced closer together as they get further from the pivot to account for the varying coverage area.
As we continued building, I learned how the pivot sections stay aligned. The farthest tower controls the others, ensuring they move in sync. This system is fascinating and shows the engineering behind the irrigation process.
After everything was in place, Trey connected the electrical lines and ran the well pipe up through the pivot point. A few months later, I returned to see the system in action. I was excited to witness how it operated and how technology has advanced farming practices.
As we harvested beans, we compared the yields from irrigated and non-irrigated sections of the field. The difference was significant, demonstrating the value of the irrigation system. Farmers truly are experts in various fields, including economics and hydrology, and they play a crucial role in providing food for everyone.
I hope you enjoyed learning about pivot irrigation with me. It was a great experience building the system and seeing its impact on crop yields. If you’re interested in more content like this, feel free to subscribe and consider supporting us on Patreon. Thank you for watching!
