Why Uniform Water Application is Essential for Crop Yield

Center pivot irrigation systems require regular maintenance, calibration, and monitoring to ensure even water distribution that maximizes crop yields.

During periods of low precipitation, irrigation systems can make the difference between a mediocre harvest season and a high-quality, high-quantity yield. However, general wear and tear on irrigation systems can lead to inconsistent water application, negatively impacting plant growth in concentrated areas throughout your fields.

Center pivot irrigation systems are particularly susceptible to these issues. A recent extension project case study from the University of Nebraska–Lincoln determined that inadequately maintained center pivots can significantly impact crop yields and profitability. For one farm in the test group, researchers estimated a combined $23,500 in crop loss for corn and soybeans as a result of failing to replace worn pivot nozzles.

To ensure your center pivot irrigation system is functioning efficiently, consider the following takeaways:

  • Conducting a simple catch-can test and analyzing results alongside yield map data can help determine whether irrigation is uniform.
  • Proactive maintenance of center pivots and nozzle replacement is essential to maximize yields. Hard water, for example, can cause parts to degrade more quickly due to mineral buildup. It’s important to know how your water quality will likely affect your equipment over time.
  • Regular calibration of your irrigation system for optimal speed, depth, and revolution is also critical to ensure even water application.
  • Access to granular crop yield data is necessary to identify field areas suffering from inadequate irrigation accurately.
