The Ultimate Guide To Crop Irrigation Systems

Introduction to crop irrigation systems

Irrigation systems are an important part of growing crops, and they can be crucial when it comes to crop yields. Without proper irrigation, many crops would not be able to grow at all.


There are a few different types of irrigation systems that you should know about before making any purchase decisions. We’ve put together a guide of the most common types so you can choose the best one for your farm.


Drip irrigation

Drip irrigation is one of the most popular types of crop irrigation systems. Drip irrigation is a method of irrigation where water is applied directly to the soil, at a rate that is measured for each individual plant. Therefore, it is highly customizable and helps to reduce water usage.


Drip systems consist of an emitter (or drip tube) that perforates the soil surface and delivers water directly to plant roots in small amounts. The most common type of drip system uses polyethylene tubing with emitters spaced along its length; however, there are also other types available such as gator tubing and micro-sprinklers that allow you to customize how much water each plant receives based on its needs.


Drip irrigation is the simplest form of water delivery, and it can be used with a timer, a pump, a filter and controller (used to control multiple zones), or even valves and pressure regulators. The drip system has many different components that are used together to deliver water directly onto your plants' roots.


Micro irrigation

Micro irrigation is a type of drip irrigation system that uses small-diameter tubing and emitters (a device that delivers water). It's often used in greenhouses and nurseries, but it can also be used in vegetable gardens, flower gardens, orchards, and even trees.


Drip Tape and Tubing

Drip tape and tubing are used in drip irrigation systems. Drip tape is a flexible plastic tube used to deliver water from the water source to the plants. It comes in different diameters, lengths, and colors. The most common diameter is 1/4 inch; however, you can also find 3/8-inch or 1/2-inch sizes on the market.


Tubing typically has an inside diameter of 3/8 inch or 1/2 inch; however, it's important that your choice matches up with what your drip irrigation system requires so that you don't get stuck with extra parts when installing your system!


Flood Irrigation

Flood irrigation is the method of distributing water over an entire field at one time. Water is distributed in a flood style, meaning it flows out of the irrigation system and covers all areas of a field before draining off.


This method is used on small areas that don't need to be subdivided into sections or zones (like lateral systems do), but instead are covered by one large sprinkler head or series of sprinkler heads.


Flood irrigation provides high rates of flow and works well with small, fragile plants like lettuce or spinach. This is because it delivers consistent amounts of water throughout their growth cycles without damaging them due to excessive moisture levels in any given area.


Sprinkler Irrigation

Sprinkler irrigation is the most common type of irrigation system. It's used for large areas of land and can be used for crops that need to be watered every day or every other day. Sprinklers spray water over crops, usually from above or at an angle from above.


It's important to note that sprinklers do not deliver water directly to plants' roots, so they're not ideal for crops with shallow root systems (like lettuce). Sprinklers are also less efficient at delivering nutrients than drip systems because they don't deliver smaller amounts of water over a longer period of time.


They're easy to install and maintain - you just need good drainage around your fields and some sort of water supply (like a well). This kind of system is also cheaper than others because it doesn't require as much equipment or labor costs. However, sprinklers waste a lot of water by spraying it out into space rather than directly onto plants; this means that not all plants may get enough water when using this method alone.


Soaker Hose

Soaker hose irrigation is a type of drip irrigation system that allows water to be applied directly to the ground. It's made up of thin tubes that run along your garden beds and allow water to flow through them, soaking into the soil rather than running off as it would with normal sprinklers or hoses. In reference to irrigation, it conserves the most water.


Soaker hoses are laid out on the ground in a series of parallel lines, with each line spaced about 18 inches apart from one another (the exact distance depends on how much pressure you want your soaker hose system to have). Once they're laid out, you can attach an automatic timer that will turn on periodically throughout each day - this will keep algae growth at bay since there won't be stagnant pools of water sitting around for too long!


Center Pivot Systems

The center pivot irrigation system uses a long, rotating sprinkler that moves along a straight line. This type of irrigation is ideal for crops that need consistent water, such as corn or cotton.

Center pivots are also used on larger areas than other types of systems - approximately 20 acres (8 hectares) per machine and up to 1,000 acres (405 hectares) with multiple machines running at once.


Center Pivot Systems Consist of Three Main Parts:

  • The head - the part that contains the nozzles and rotates in one direction or another depending on whether you're using clockwise or counterclockwise rotation mode;

  • The drive mechanism - which powers the entire system; and

  • A pressure tank - a container filled with pressurized water that sends it through tubes under pressure so they can reach their destination.


Gravity-Fed Systems

In a gravity-fed irrigation system, water is fed to the plants through pipes that run along the ground. The water flows down from an elevated tank and into the main line by way of a pump or siphon.


The Benefits of Gravity-Fed Irrigation Include:

  • Efficiency: Gravity-fed systems use less power than electric pumps; therefore, they're more energy-efficient than electric systems. They also tend to cost less since there's no need for electricity or batteries in the field - you only need one line going from your tank/pump house into each row you want irrigated (and then branching off into smaller lines).

  • Easy Installation: These systems are easier to install because they require fewer parts than many other types of irrigation methods such as drip systems or sprinklers. Once everything has been laid out properly, it shouldn't take more than half an hour per acre-foot (.5 acre) of water spread across several acres worth of crops!


Importance of crop irrigation systems

Crop irrigation systems play a crucial role in modern agriculture by providing a reliable and efficient way to water crops. With changing climate patterns and increasing water scarcity, farmers need to use water more efficiently to ensure maximum crop yield.


Irrigation systems allow farmers to deliver precisely the right amount of water to their crops, which can help reduce water waste and improve the overall health of the plants. Additionally, these systems can help farmers maintain crop stability during droughts or periods of low rainfall, ensuring a consistent and reliable food supply.


Overall, crop irrigation systems are essential to the success of modern farming practices and are key to meeting the growing demand for food in a sustainable way.


A key aspect of any of these irrigation systems is soil moisture.


Final thoughts on irrigation systems

As you can see, there are several different types of crop irrigation systems to choose from. When choosing an irrigation system for your farm, it’s important to consider the advantages and disadvantages of each.
