A refractometer is used to measure brix, the sugar content in plants. Understanding the quality of your forages will help you adjust the forage options for your livestock.

Tips for an accurate brix reading

• Be sure to take your reading on a sunny day.

• Only include forages your livestock are actually eating.

• Choose a variety of plants for your tests.

• Double check your reading by taking tests at different times of the day.

If your brix reading is low, work to improve the soil biology in your pastures.
