THE CONTROL OF WEEDS IN HIGH FERTILITY PASTURES

Abstract

Weed control in high fertility pastures is seen as the correction of errors in management or of the effects of breakdown, through vagaries of climate, of management practices known to maintain clover balance and give maximum animal production. The possibility of build up of excessive soil fertility in low rainfall areas and possible remedial actioil is noted. The present control measures for Californian thistle, docks and barley grass are described. The need for economic assessment of pasture weeds in terms of animal production is noted.
