| Abstract:
Composting is an attractive option for processing organic wastes because it reduces mass and volume to provide a well-humified material. The potential for generating large quantities of green waste from households means that high-volume end uses are preferable. Agriculture provides such an outlet, and compost offers many opportunities such as fertiliser replacement and improvement of impoverished soils. In the current trial, green garden waste was composted and applied to a sandy loam soil at rates of up to 150 tha-1, and yield parameters were measured at harvest. At the highest rate, there was a significant (25%) increase in plant dry matter, and evidence of an increased number of tillers per plant relative to untreated soil. There was no change in the quality of the grain as assessed by N-content and 1000-grain weight. | |
