The Prospect For An Asparagus Industry In Northern Western Australia, John Bonnardeaux

Horticulture published reports

Asparagus grown in temperate regions of southern Australia is available, fresh, between August and March. For the remainder of the year, asparagus is not grown in Australia on a significant scale.

Recent work in Thailand, Peru, Kununurra (northern-western Australia) and Katherine (Northern Territory) has indicated that good quality asparagus can be produced in tropical and subtropical climates. Furthermore, research has shown the timing of the harvest can be manipulated by withholding irrigation and fern cutting. In an environment such as the Ord River Irrigation Area (ORIA) it is possible to harvest asparagus at any time of the year.

Bulletin 4328 - Soil Testing For Vegetable Production On The Coastal Plain, Ian Mcpharlin, Murray Hegney

Bulletins 4000 -

Vegetable growers need to use fertiliser efficiently. Under-fertilising can reduce yield, which results in economic losses. Over-fertilising can reduce yield and contribute to nitrogen and phosphorus pollution of ground and surface waters. Concerns have been expressed that fertilisers applied to horticultural crops contribute to the phosphorus pollution of the rivers and estuaries of the west and south coast of Western Australia.

Soil testing is a technique that can be used by growers to make better fertiliser decisions. When soil tests show high levels of nutrients, growers can reduce fertiliser application for the current crop. This should enable growers to maintain …
