Proper care for a long time undergrazed cow pasture
I recently inherited a small (12 acre) farm in the central willamette valley. My inlaws kept 5-10 cows and a bull for many years(40) on 9 acres pasture. About 5 years ago the got rid of all but the bull and a cow and stopped doing anything with the pasture to keep it from getting full of pick Marc's, pot holes, nasty muck holes and such. I recently was told to mow the grass down with the brush hog so that the young grass can grow. Having abused my back for half a day out in the rough, I decided to give this a shot at the recommendation of my cousin who has a farm in NH. So, my question is rather General but multi faceted. In short...what do I do? Eek I've gathered some info and it seems I should: address drainage to properly deal with the sink holes. Some sort of cultivator to break up the clumps and somewhat deal with the "potholes" As far as tools I have this 83 Ford 1710 tractor, a very old(steel wheel) two bottom plow that works great, a 3 point tiller, a 3 point straight blade, the brush hog and a case 580 superL backhoe to work with. Is there other tools I should acquire to achieve the task at hand reasonably and anything else I should do to the soil? Does it need fertilizer on top of the cow "leave behinds"? We do have a bull, 4 cows a heifer and a steer now. The bull a cape ant the heifer are in a 2 acre "pen" and the others are on the other 7 acres. Should these areas be further split to control their grazing and better keep the grass down? Any help is greatly appreciated.
