Some Effects of Nitrogen Fertilization on Vegetative Composition and Yield of Permanent Pastures Given Differential Weed Control and Grazing Management Treatments
Abstract
The bluegrass pastures of Eastern Nebraska have come into being almost by accident, and very few, if any, have been intentionally planted. From the mass of older litera- ture on the subject it is reasonable to assume that these farm pastures once contained mostly native grasses, legumes and broad-leaved weeds.In general the history of farm pastures of the plains area has consisted of a long period of heavy grazing pres- sure followed by a reduction of the native warm-season grasses and their eventual replacement by Kentucky blue- grass, Poa pratensis L., and increased populations of both native and introduced broad-leaved weeds. There has been great seasonal differences in total plant production from such pastures, and these differences seem to have been due to the amount of soil moisture from year to year.
