Why do moisture meters need quantitative moisture readings?
Why is it so important to make quantitative moisture measurements? The reasons may vary from one industry to another. To highlight the importance of quantitative moisture readings, here are some examples from different industries:
1. Agricultural industry and moisture quantitative readings
In the agricultural industry, it cannot be overstated how important it is to have accurate moisture measurements to optimize harvest time and verify that harvested crops are ready for storage. However, for some applications the issue of hygrometer accuracy is more pressing than for others.
One part of the agricultural industry where accurate, quantitative moisture measurement is indisputably important is the storage of hay or other tightly bundled forage. If the hay is too wet when collected, bacteria may grow out of control. The result of this in mild cases is that the bacteria can cause the hay to break down, losing its nutritional value, forcing farmers to abandon their hay.
In the worst-case scenario, growing bacteria can cause bales of hay to spontaneously combust, causing fires and dust explosions in barns or hay bins. This clearly poses a risk to the health and safety of farmers, livestock or anyone within the blast and shrapnel radius of the explosion.
The satisfactory moisture content of the bale depends on the type of bale. Generally, the denser the bale, the less moisture it will retain before it becomes a serious safety hazard. Here are the acceptable moisture ranges for different types of hay:
Small square bag. These bales tend to be less dense than other types of bales. Ideally, these cotton bales should have 18% to 20% moisture for a good balance of quality and safety.
Generous package. The density is higher than that of small square bales, but the moisture resistance of large square bales is lower. The satisfactory humidity range for these cotton bales is 12% to 16%.
Round hay bales. These bales are similar in density to large square bales. Therefore, it is generally better to keep their moisture content at 15%.
Without quantitative moisture readings, it is nearly impossible to determine that the moisture content of tightly packed hay is within the acceptable moisture range. If the bale is too dry, the nutritional value of the hay will be compromised due to leaf loss. If a bale is too wet, the bale may catch fire.
Therefore, in the case of measuring hay moisture, you need to have accurate readings.
Quantitative readings are also useful for other crops such as cotton, tobacco and cereals to prevent spoilage or release of free dry weight when selling these crops.
