Why is Testing Moisture in Hay Important?  

testing moisture in hay

Time to make hay! Or perhaps you are getting ready to store your hay. Your geographic location can determine what phase of hay production you are in. Regardless, it’s important to ensure you are testing moisture in hay. 

At BioZyme®, we focus on animal health and nutrition for all animals. We know that several species, including horses, cattle, sheep and goats, depend on high-quality hay throughout the year, especially the forthcoming winter months. 

Although we know that most of our customers conduct forage testing for protein and other nutritional components, it is also important to test for moisture.  

That is why our team developed this blog. We want to help producers and animal lovers like you with the information they need to stay safe and provide their animals with the best nutrition possible. 

When Should I be Testing Moisture in Hay?  

Testing for hay moisture is crucial to ensure safe storage and quality. There are a few key times when it is best to test for moisture.  

Before Baling  

Test moisture right before baling. Ideal moisture levels vary by type of hay, but typically: 

  • Small square bales: 18-22% 
  • Large round or square bales: 14-18% 

After Cutting but Before Baling  

If you’re conditioning or tedding the hay to dry it, testing in the field during drying helps track progress. 

During Baling  

During baling, periodically test hay moisture to ensure consistency, especially in different parts of the field. 

Before Storage  

We highly recommend testing moisture after baling, before stacking in storage. Moisture levels above 20% can lead to mold growth and potential fire risk from spontaneous combustion. 

How to Test Hay Moisture 

Use a hay moisture meter to test the moisture levels in your hay. If you are going to be making or storing hay on a regular basis, the one-time investment of this handy tool could pay off over time.  

Why is Testing Moisture in Hay Important?  

Testing moisture in hay is crucial for several reasons related to quality, safety and economic value. Let’s look at the 5 reasons you should test your hay for moisture. 

1. Preventing Spoilage & Mold 

High moisture content in hay can lead to mold growth, making the hay dangerous or undesirable for livestock consumption. Mold can cause respiratory issues or other health problems in animals. 

2. Preventing Fire Hazards 

Hay with excessive moisture can undergo spontaneous combustion due to microbial activity, leading to heat build-up inside the bale. This poses a significant fire risk in barns and storage areas. We often read about tragic fires of barns and hay facilities each year due to this very issue. 

3. Maintaining Nutritional Value 

Hay with too much moisture could lose nutrients during the fermentation or spoiling process, reducing its feed quality. Testing moisture in hay helps ensure that the hay retains its full nutritional potential. 

4. Economic Value 

Excessively moist hay is heavier, which can lead to buyers paying more than the actual value due to the water weight. Testing ensures that those buying hay are accurately pricing hay based on its dry matter content. 

5. Storage Efficiency 

Hay with proper moisture levels stores better and longer without deteriorating. This allows for better inventory management and reduces losses over time. It is also easier and more efficient to stack hay at the proper moisture level. This once again makes storing hay safer. 

By keeping moisture levels in check, producers ensure the hay’s quality and safety for both animals and storage conditions.
