Storing Alfalfa Indoor vs Outdoor
Alfalfa is a highly nutritious feed for livestock and can be stored for long periods if stored correctly. Two common methods for storing alfalfa are indoor and outdoor storage methods.
- Indoor Storage: Alfalfa stored indoors can last for up to two years if stored properly. Indoor storage is preferred for areas with extreme weather conditions as it protects the hay from the elements. Proper ventilation is crucial in ensuring that the hay stays dry and mold-free. The best way to ensure proper ventilation is to stack the bales in a pyramid or vertical fashion with proper spacing between them. This allows for air to circulate around them and prevent moisture build-up. Moreover, storing alfalfa indoors prevents it from exposure to any pests or rodents that may otherwise destroy the hay.
- Outdoor Storage: Alfalfa stored outdoors has the potential to last up to a year if stored properly. However, outdoor storage is not the preferred method as it is exposed to the elements which can cause mold and spoilage. Moreover, outdoor storage increases the risk of loss due to pests or rodents, especially if the bales are not stacked properly. Storing alfalfa outdoors is only recommended if there is a shortage of indoor storage or if there is limited space available. If using outdoor storage, it is essential to ensure that the bales are tightly packed, covered, and kept off the ground to prevent moisture build-up.
Factors Affecting Alfalfa Storage Life
The following factors can affect the longevity of alfalfa storage:
- Moisture: Alfalfa hay should be stored in a dry and well-ventilated area to prevent moisture build-up and mold. Moisture can cause the hay to spoil and decrease its nutrient content.
- Temperature: Alfalfa hay should be stored in an area where the temperature is consistent, cool, and dry to prevent spoilage. High temperatures can cause the hay to dry out and become brittle, while low temperatures can cause moisture build-up, resulting in mold growth and spoilage.
- Pests and rodents: Pests and rodents can cause significant losses in alfalfa hay. Proper storage methods, such as stacking bales in a pyramid or vertical fashion, can help deter pests and rodents from destroying the hay.
- Bale density: The density of bale packing can also affect alfalfa’s storage life. Properly packed bales can help prevent air pockets that can lead to increased moisture levels and spoilage.
Conclusion
Storing alfalfa indoor and outdoor has its advantages and disadvantages. However, proper storage methods such as keeping the hay dry, well-ventilated, and off the ground are essential in ensuring the longevity of alfalfa storage. Properly stored alfalfa can last for up to a year if stored outdoors and up to two years if stored indoors.

How to properly dry alfalfa
Properly drying alfalfa is crucial in preserving its quality and extending its shelf-life. Here are some tips on how to dry alfalfa the right way:
- Cut the alfalfa during the mid to late-bud stage, as this is when the plant has the highest nutrient content.
- Avoid cutting the alfalfa during the early morning or late evening when there is dew on the ground, as this can lead to mold growth.
- Use a mower-conditioner to crimp the stems and speed up the drying process. This breaks the waxy coating on the alfalfa stems and allows the moisture to escape faster.
Once the alfalfa is cut, there are two main methods of drying:
- Field drying: This involves spreading the cut alfalfa in rows to dry in the sun. It can take anywhere from 3-5 days depending on the weather conditions.
- Dehydrator drying: This method involves using a specialized machine to dry the alfalfa in a controlled environment. This is a quicker method, taking only a few hours, but it can be more expensive.
It’s essential to monitor the alfalfa during the drying process to ensure it doesn’t over-dry or become overexposed to the elements. Over-drying can cause the alfalfa to lose its nutritional value, while overexposure can increase the risk of mold growth.
If you’re not sure when the alfalfa is dry enough, check the moisture content using a hay moisture tester. The ideal moisture content is around 15-20%.
| Drying method | Time required | Pros | Cons |
|---|---|---|---|
| Field | 3-5 days | Cheaper than dehydrating | Drying time is affected by weather conditions |
| Dehydrator | A few hours | Fast and efficient | More expensive |
Properly dried alfalfa should have a green color, a sweet smell, and feel crispy to the touch. It can be stored in a dry, cool place for up to a year, but its quality will gradually decline over time.
The Impact of Moisture on the Longevity of Alfalfa
Moisture is one of the critical factors that can significantly affect the longevity of alfalfa. Alfalfa, like other forage crops, is subject to natural degradation, causing losses to both farmers and livestock producers. Moisture content can affect plant respiration, microbial growth, and nutrient availability, which ultimately impact the quality and nutritional value of the forage.
- High moisture levels: Excess moisture can lead to the sprouting of alfalfa before harvesting, resulting in decreased forage quality and nutritional value. Wet hay can also provide an ideal environment for bacteria and mold growth, which contribute to spoilage, musty odors, and plant toxicity.
- Low moisture levels: On the other hand, too little moisture can cause the plant to dry out and undergo leaf shattering and pod loss, leading to reduced forage yield and quality. In cases of extreme drought, alfalfa becomes dormant and stunted, further reducing yield.
- Optimal moisture levels: To maximize alfalfa longevity, farmers must strive to maintain ideal moisture levels between 10-15%. Proper baling and storage techniques will also ensure that alfalfa stays fresh and free from moisture-related deterioration.
Table below summarizes the relationship between moisture content and alfalfa longevity:
| Moisture Content | Effect on Alfalfa |
|---|---|
| 10-15% | Optimal moisture for maximum longevity and nutritional value. |
| Less than 10% | Leads to leaf shattering and pod loss, causing reduced yield and quality. |
| Greater than 15% | Results in sprouting, bacteria and mold growth, and decreased forage quality. |
Farmers must stay vigilant in monitoring moisture content, particularly during harvest and storage, to maximize the general quality and longevity of alfalfa. By following proper baling techniques and storing the forage in dry conditions, you can make the most out of your crop and ensure a high-quality feed source for your livestock.
Shelf Life of Alfalfa Hay vs Alfalfa Pellets

Knowing the shelf life of alfalfa hay and pellets can help ensure that your animals are getting the best feed possible. Proper storage is key in extending the shelf life of both types of alfalfa. Make sure to purchase in small batches, to ensure freshness, and always inspect the hay or pellets for any signs of spoilage before feeding it to your animals.
The Impact of Processing on Alfalfa Shelf Life
Alfalfa is a highly nutritious and versatile forage crop that is widely used as feed for farm animals. However, like all agricultural products, it has a limited shelf life. There are several factors that affect the shelf life of alfalfa, and processing is one of the most significant.
Processing refers to the various treatments that alfalfa undergoes before it is packaged and sold. These treatments can have a major impact on the quality and longevity of the product. Here are some of the ways that processing can affect the shelf life of alfalfa:
- Drying: One of the most common ways to process alfalfa is to dry it, either naturally or using mechanical means. Drying helps to remove moisture from the crop, which can prevent spoilage and extend its shelf life. However, over-drying can cause the alfalfa to become brittle and lose some of its nutrient content.
- Baling: After drying, alfalfa is often baled into compact packages for storage and transportation. The size and shape of these bales can affect the air circulation around the crop, which can impact its shelf life. Bales that are tightly packed may not allow enough air to circulate, while those that are too loosely packed can become compressed and spoil more quickly.
- Treating: Some alfalfa crops are treated with preservatives or other chemicals to prevent spoilage and extend their shelf life. These treatments can be effective, but they may also leave residues that can be harmful to animals that eat the alfalfa.
To get a better understanding of how processing affects the shelf life of alfalfa, let’s take a look at this table:
| Processing Method | Shelf Life |
|---|---|
| Natural Drying | 2-4 weeks |
| Machine Drying | 4-6 months |
| Preservative Treatment | 6-12 months |
As you can see, the type of processing that alfalfa undergoes can have a significant impact on how long it will last. Natural drying may be the simplest and most natural method, but it also has the shortest shelf life. Machine drying can extend the shelf life, but at the cost of some nutrient value. Preservative treatments may offer the longest shelf life, but they also come with some potential risks.
It’s important for farmers and livestock owners to understand the impact of processing on alfalfa shelf life so that they can choose the method that best meets their needs. By carefully managing the processing and storage of their alfalfa, they can ensure that it remains a high-quality and nutritious feed source for their animals.
Does baling affect the storage duration of alfalfa?
There is a debate among farmers and experts on whether baling affects the storage duration of alfalfa or not. Some believe that baling could reduce the quality and shelf life of the forage, while others argue that it is necessary to preserve the crop and prevent spoilage.
- According to a study conducted by the University of Minnesota Extension, the manner in which alfalfa is baled can determine its storage duration. They found that small square bales have a shorter shelf life than larger round or square bales. This is because small bales have a higher surface area to volume ratio which increases the exposure of the forage to moisture and air.
- The study also suggests that the moisture content of the forage at the time of baling plays a crucial role in determining the storage duration. Alfalfa with high moisture content is more susceptible to bacteria growth and mold formation, which can reduce the nutritive value and palatability of the forage.
- Another factor to consider is the use of preservatives and additives during baling. These products can help reduce moisture content and prevent spoilage, but their effectiveness depends on the application method and the quality of the forage.
Overall, baling can affect the storage duration of alfalfa, but the extent of its impact depends on various factors such as the bale size, moisture content, and the use of preservatives. Farmers should consider these factors when deciding on the baling process to use and ensure that the forage is stored in ideal conditions to maximize its shelf life.
The Ideal Temperature and Humidity Conditions for Alfalfa Storage
Alfalfa is a valuable forage crop that is used as feed for livestock. It is important to store alfalfa properly to maintain its nutritional value as well as prolong its shelf life. One of the key factors to consider when storing alfalfa is the temperature and humidity conditions.
