How long has it been
since your dry spreaders were calibrated?
Properly calibrated and maintained equipment ensures the uniform distribution of nutrients. This can be essential to your relationship with your customers. Your spread pattern serves as a billboard attesting to the quality of services and products you provide. Combined with other conservation practices, calibration reduces production costs and nutrient movement to surface waters.

The amount of time required to properly calibrate a spreader is minimal compared to the amount of money that can be lost by incorrect rates of application. Applying too much is costly, unlawful and may cause crop injury. Applying too little can result in poor crop growth and production. It’s important to calibrate equipment on a regular basis.

Course Objectives
Training is provided to teach your employees or participants how to perform this important activity. This is not a service we offer to calibrate your equipment, but rather an effort to provide the industry with high quality training at locations near you. The goal is to increase the awareness of the importance of dry calibration and multiply the effort of those qualified across the country to perform what should be at least an annual requirement for each piece of dry application equipment.
About This Training
It’s recommended that equipment be tested prior to each spreading season! Every facility should have someone onsite properly trained and qualified to conduct these tests. This course is designed to provide the hands-on experience required to make your employee feel comfortable with this critical responsibility.

This course utilizes a special New Leader bed custom built for this course to simulate real world field situations. The course is offered remotely throughout the U.S. via a unique self-contained tractor and trailer combination.

Spread pattern is affected by a number of factors, including:
  • Spinner speed

  • Granule size
  • Flow of material
  • Rate of the delivery of material
  • Point of drop onto the spinner discs
  • Requirements for facilities with rail
  • Wind speed
  • Humidity
  • Hardness of the granule
  • Mechanical condition of the spinner fins and discs
  • Cleanliness condition of the spinner fins and discs
  • Spacing of swaths
  • Condition and wear on spinner fins
  • Angle of the distributor fins on the spinner discs
