Drought is definitely affecting hay and other crops here locally. I got 19.5 500+ lb. round bales off my first cutting. Fertilized a day after baling as they were calling for 80% chance of rain w/3/4" - 1" expected. Barely got 2/10's and has been hit & miss all Summer. Didn't even get enough rain to set the fertilizer. Just made second cutting last week, and it had a lot of Foxtail in it. Ended up with 5.5 bales.
Hay was a little damp in the morning so tedded it up to dry for an hour. Raked, then gave it another hour to dry. Humidity was down to 24%, and in areas where it was mostly Fescue grass it was so dry, the pickup fingers shattered it into 3"-4" pieces. I plugged the baler 2X.
Good thing I get enough off of first cutting to get the kids through the winter. Still have 80% of last year's second cutting. I gave this year's second cutting to a buddy for his goats, as his paddock is bare dirt. I just wanted this grass with Foxtail in it off the field. I more than likely shattered seed out of the Foxtail, but hopefully will cut before going to seed next year, or at least not as bad.
May not have to worry too much about fertilizer next year, as we didn't get enough rain to really set it in. I only put on P&K I sowed Renovation Clover on a couple years ago for a source of N. Too many times of spreading Urea, and again the weather service prediction of a good rain missed us to set it in before evaporating into the air.
The Renovation Clover (name brand) has done a very good job of providing N. It's not cheap, but a lot cheaper than N going into the air. Sowing rate is suggested at 1 lb. per acre so it goes a long way. The seed dealer warned me that if applied at a heavier rate, like 2 lb. per acre it can become invasive. I put 5 lb. on 4 acres and it's doing a great job.
I used the "Frost Seeding" method to sow it on and worked great.
