Last year I purchased a farm in Upstate New York, that had pastures over run with multiflora rose and thorns, my daughter and I renovated 10 acres by brush hogging, chain sawing and even dozing out some of the roses. I tried to be as low impact as possible as we had cattle in the pasture that needed the grass. The pasture was populated with native grasses, mostly timothy and some clover along with various weeds. I mowed the entire pasture twice in five sections about 5 weeks apart. I wanted to fertilize the pasture, but the thorn stubble from bush hogging deterred me from putting heavy equipment with pneumatic tires on it so I used a small spreader behind an ATV and yes we had to repair the tires on the ATV. I was unsure what to fertilize with so I did a test using 100lbs of urea on one acre along with 200 lbs of lime on the same acre. Last year, that part of the pasture seemed to be a little better than other parts, but not a lot better. This spring, the fertilized area was 3 to 4 times better than the un-fertilized portions of the pasture with a heavy stand of timothy and clover. I want to improve the rest of the pasture as economically as possible, but I am not sure what did the trick. The lime was minimal at that rate and I would have thought that the nitrogen would have been used up long ago. So what is likely to have caused the great difference in that part of pasture, the lime or the urea or both and what should I do with the rest of the pasture this year or was it that the cows spent more time there last season depositing more manure and urine there due to the sweeter grass making the soil more fertile this year?
