Okay, so technically we don’t actually make hay while the sun shines, as our farm isn’t big enough to warrant buying a hay baler. Instead, we buy hay from someone who sells small bales, as they are much easier for us to handle.
It’s not always easy to find good quality hay in small bales, because most farmers bale the great big rolls of hay. I reckon finding people to work in a hay field during hot summer weather is rather difficult these days, and big rolls of hay can be handled by one guy with a tractor and the proper equipment.
However, it’s still good to get hay while the sun in shining, because you don’t want wet hay! Storing a bunch of wet hay is a good way to a) end up with moldy hay, or b) set your barn on fire.
Obviously, moldy hay isn’t good to feed the animals. And just as obviously, you don’t want the hay to catch fire because it was wet. Sounds a little weird to say storing wet hay can result in a fire, doesn’t it? It’s that good old spontaneous combustion thing!
If you’re not familiar with the phenomenon, it happens because wet hay can create a high relative humidity in the air around it. This allows plant and microbial respiration in the hay which generates heat, elevating the temperature of the hay.
As the hay gets hotter, the microbes die which causes “oxidative chemical reactions” that increases the temperature of the hay even more. Once the temperature gets to 140 to 150 degrees, the process accelerates and by the time it hits 175°F (80°C), farmers are advised to call the Fire Department. No kidding!
If the hay temperature gets to 212° (100°C), the process is too far gone to stop. The temperature rises rapidly at that point and the hay is almost certain to catch fire.
Of course, a lot of things affect if and when this happens, but the critical factor that starts it all is wet hay. So there we have it, the reason why it’s good to make hay while the sun shines!
And the sun was shining brightly this past Saturday when we got our hay. It took The Farmer three trips to get it all hauled. The guy selling the hay helped him load it at that end, then when he got home, The Cave Geek and I helped unload it.
Actually, I only rolled a few closer that fell short of the storage hut. The men did most of the work, while Toby and I watched. That sounds like a pretty good deal, doesn’t it?
The Geek became quite adept at tossing those bales into the shed so all The Farmer had to do was toss them on the stacks.
It’s tiring work, and when the bales quit flying through the air, Toby went in to inspect the new pile of hay.
He and The Farmer are best buddies, so while The Farmer rested from his labors, Toby kept him company.
And now we’ve got hay to feed when the grass dies back during the coming winter. It feels good to be prepared!
