Hay Probe Equipment Loan

A hay probe is a sharpened tube that is used to take a representative sample of the forage in a bale of hay. The King Conservation District has a hay probe (also called a core sampler) available for loan at no charge! The hay probe is used to collect forage samples that can be sent to a laboratory for analysis. Knowing the nutrient composition of hay can help you match your feeding program to animal requirements or help with hay marketing.

For more details about how to use the probe, see the Hay Probe Fact Sheet
