Questions:
If you are going to wrap them in plastic why spend the extra buck to put them in netwrap? Why not use twine? It can't be that you are in a hurry because if you have time to wrap every bale with plastic then you have plenty of time.
Which brings me to my second question: How long does it take to wrap one?
What does it cost per bale?
So if the plastic is airtight, the bale stops the drying process as soon as it wrapped? So it's not haylage but it's not fully cured hay either.
I'll try to answer your questions:
1. I purchase all of my winter hay. I do not have the time, equipment or acres to bale my own. Netwrap is what my regular and very good supplier uses, I assume because it is faster in the field. He occasionally uses plastic twine for some of his other customers. I have bought a few of those bales also and for my purposes I see no difference so I'll take whatever he chooses to use, which is usually netwrap for speed.
2. It takes me about 2 minutes additional time to wrap, maybe 3 minutes.
3. With the open ends it is obviously not haylage nor is it airtight. I have found it works better to put a couple extra wraps on the OD (from what the instructions say) and stretch it tight to prevent most ground water from coming in on the bottom and rain from coming in at the top.
Is it fully cured hay? Well it has been several days since baled by the time I pick them up and wrap them. This has been a very difficult year to get hay dry in Wisconsin. I went back and forth between packing the bales tight end to end vs leaving a space and in the end took my neighbors advice and left about a foot between bales so they can breathe.
As far as cost, the machine cost about $2300. the plastic is about $2 to $3 per bale depending on how much I use. If we say the life of the machine is 5 years and amortize that at about 100 bales/year then the machine cost is about $5/bale or with plastic about $7 or $8/bale total not counting my time and the tractor which would be moving the bales anyway.
I have found that in my climate the wrapping saves a lot of hay in the outer foot of the bale by springtime. At the cost of good hay and since a large portion of the hay in a round bale is in the outer foot and since I don't have the space nor money to build a big enough building which sits empty half the year the wrapping pencils out well for me.
These are just in my specific situation. I'm sure in Texas the idea of not having room to build a hay storage building sounds absurd but in my hills and small farm it is not.
Hope this answers your questions. Jim
