Informational Videos Covering Fertilizer Application through Irrigation Water
Now Available in English and Spanish
Nicole Nunes FREP Grant Program
Through a grant from the Fertilizer Research and Education Program (FREP), Cal Poly's Irrigation Training and Research Center (ITRC) has developed a series of informational videos covering chemicals, application hardware, techniques, and timing of fertilizer application through irrigation water.
The videos are based on information provided in the Fertigation book developed by ITRC and updated in 2019. The Fertigation book is also available in English and Spanish and can be downloaded for free from the ITRC website: https://www.itrc.org/books/index.html
The 22 informational videos are available on YouTube or through the ITRC website and cover the following topics:
- Overview
- Basic Fertilizer Chemistry and Vocabulary
- Nitrogen and the Environment
- Basic Soil Principles
- Crop Fertilizer Requirements
- Testing of Plants Soil and Water
- Fertilizer Labels Characteristics and Usage
- Nitrogen Conversions
- Volatilization of Ammonia from Irrigation Water
- Irrigation System Uniformity and Efficiency
- Safety
- Purging Media Tanks of Chemicals
- Calibration, Titration, and Travel Time
- Varying Venturi Injection Rates
- Chemigation for Soil Infiltration Problems
- SO2 Generators (Sulfur Burners)
- Chemigation for Drip System Maintenance
- Incompatibility of Different Fertilizers
- Proportional Injection
- Fertilizer and Chemical Injection Devices
- Calibration of Fertilizer and Chemical Injectors
More Fertigation Resources Coming Soon
ITRC is developing the informational video series into a Fertigation Certificate Program available to the irrigation and fertilizer industry. The videos will be coupled with information and suggested readings from the Fertigation book to create a comprehensive online course. Course participation will be verified with an exam on the presented materials and successful participants will receive a certificate of completion.
Stay tuned for more information regarding the availability of the certification program.
