A high density legume mix suited to medium and higher rainfall
zones that provide outstanding dry matter production and nitrogen
fixation. A HDL break crop in rotation is also an effective
and profitable way of managing herbicide resistant annual ryegrass
and increasing soil nitrogen. A vigorous SOWsmart HDL
blend can contribute up to 50 kg/ha of nitrogen for subsequent
crops, the equivalent of 100 kg/ha of urea. With appropriate livestock
management the pasture can generate an income in its own
right. In cropping only enterprises, green manuring of the HDL
crop also dramatically increases soil characteristics of organic
matter and carbon content.
Brown and green manuring are also the most effective means of
preventing ryegrass seed set.
