nw NC | A few years ago I renovated a grassland field that my dad had planted in the 1950's. It had been used for pasture and hay. I used chisel plow, disk , field cultivator, drag spike tooth harrow , rock picker and culti-mulcher to get the field in shape for seeding. Using grain drill , I planted fescue with some winter wheat as a nurse crop. Wheat and fescue established well. Next summer there was the thickest stand of common ragweed that you could imagine growing in the field. The field was a hillside and there was a heavy rain event that winter that caused some small rills to form where there was runoff. Where this soil was deposited in areas of grass down hill from the renovated areas the soil that moved downhill also grew ragweed profusely. I had never seen any ragweed growing in that field before. Ragweed seed must be extremely long lived buried in soil. | |
