Contaminated Hay
Many factors should go into your hay buying decisions. The hay you buy should look good, smell good, and be free of mold and contaminates. These days with the high cost of machinery the wise hay buyer should not only look at the product they are buying but the machinery that put it up.
A typical hay field is first driven over by a tractor pulling a harrow. Then by a tractor pulling a mower or a self propelled mower. Then often times by a tractor pulling a hay rake. Then by a tractor pulling some kind of baler. And finally by a tractor pulling a bale wagon or a self propelled balewagon.
The only emmision control system on older farm machinery is a tube pionted toward the ground that allows oil, unburnt fuel and crankcase waste to be dumped directly onto the hay. Equipment not very well maintained also leaks large amounts of hydraulic fluid, oil, and diesel or gas directly onto the hay.
If you were to spill a 5 gallon pail of these substances onto the highway an emergency hazmat team would be called out to contain and dispose of them.
Like wise if you were to buy hay put up along the roadside it would not only contain all these contaminates but all the chemicals washed off the roadway by the rain.
Assuming a farmer running poorly maintained equipment makes five passes across a hay field and drops 1 gallon of these fluids per acre and the field yeilds one and one half ton of hay per acre. That is the equivilent of you pouring almost one half cup of toxic waste on each bale of hay you feed.
Of course not all farmers run this kind of equipment but it is definately something to consider when selecting your hay provider.
