A survey of the use of lucerne, butterfly pea and lablab in ley pastures in the mixed-farming systems of northern Australia

Abstract

A farmer and paddock survey of ley pastures was conducted across the northern mixed-farming region to identify producers' attitudes to, and expectations of, ley legume pastures, the persistence of perennial legume species and the build-up of soil carbon (C) under ley pastures. Six butterfly pea (Clitoria ternatea) growers in central Queensland, 8 lucerne (Medicago sativa) growers in southern Queensland/northern New South Wales and 6 lablab (Lablab purpureus) growers (across both regions) were surveyed. The species played different roles in farming systems. Lablab was used as a short-term pasture to build soil fertility in crop rotation. Lucerne was used as a phase pasture (3-5 years) in crop..
