Grazing and Fertilization Affect Root Development of Range Grasses

Grazing intensity of native range had little effect on total root weight, but under heavy grazing the percentage of total roots in the upper foot was greater than under moderate grazing. Thirty lb of N significantly increased root weight in the 4-ft profile. Ninety lb of N did not further increase root weight although top growth was significantly increased.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
