Hey guys I wondering if I could grab any ones opinion about putting grain on pads with tarps over it. How do you find it to handle as well as keeping birds out of it an how long they last for
Generally you want to move the grain on the ground by thaw. That includes bags, tarps, bare piles, rings, etc. If you have a concrete pad(I would like to know where you got that from) you may not have to play by those rules. Racoons and ravens can be a problem but you will be ok if the pile is close to home and you can monitor it well. Considering the price and quality of the grains in the canadian prairies this year I doubt you can justify the cost of a tarp even.
A couple years ago made a pile and tarped it with black/white silage poly. Had a real bad time with the ravens tearing the tarp up. Couldn't keep up with the 12 ga. Put a torn up blue poly tarp on top and that seemed to scare them away.
I have a friend who after filling a grain bag sprays several gallons of diesel down the top and claims the birds never bother it. I've never tried it though.
What about a parachute? There was always someone advertising old parachutes in the western seducer. Hard for a raven to pick them apart. Grain bags around here fell prey to ravens and all wild ungulates of the area. I hear elk are the worst. If grain is piled in this area a ring of round bales is placed on end and then a couple bands of barb wire is wrapped around and stretched. Grain is put in it but seldom covered because it's usually hauled before spring. I can't see why you couldn't cover it past the bales a make for a decent seal. Heck even a big hay tarp and placing bales in a rectangular fashion wouldn't work neither. Only problem is having to shovel off snow.
used a parachute once it worked great, also used silage plastic and it worked as well, think the plastic is cheaper, just put a bunch of round bales on it to keep the wind away and like Snapper said get it cleaned up asap.
