The net benefits from growing lucerne in the Broken Plains area of north-eastern Victoria

چکیده
Abstract. The clearing of trees and native vegetation over the past 160 years has caused deep drainage to groundwater in the Broken Plains area. Predictions are that continuing recharge will bring the water-table to within 2 metres of the surface over the next 30 years. This will lead to water-logging and dryland salinity. A solution is to introduce deep-rooted perennial species such as lucerne. Lucerne extracts more water than annual crops and pasture. Farmers in this area believe that lucerne is riskier than annual legume pastures. Results of this analysis show that the change to lucerne increases expected profitability and cumulative net cash flow.

Clearing of trees and native vegetation over the past 160 years has led to increasing rates of dryland salinization in the Goulburn-Broken Catchment area. In its dryland section, within the Goulburn Highlands, South West Goulburn, and the Broken Highlands subcatchments, hydrologic balance exists. But in the Riverine Plains comprising the Goulburn and Broken Plains sub-catchments, where average ...

متن کاملPotential returns and risk of growing aluminium-tolerant lucerne in a grazing system with acidic soils located in the high rainfall zone
The benefits, costs and risk from introducing aluminium-tolerant lucerne (alfalfa) into a sheep grazing enterprise, consisting of a perennial ryegrass-based pasture, located in the high rainfall zone of Victoria, Australia, were estimated using a discounted cash flow analysis. Two ‘what if’ scenarios were compared for a modelled representative case study farm; 1) where aluminium toxicity occurr...

An experiment was carried out to compare the effect of feeding posidonia australis as a non-conventional feedstuff with cereal straw for sheep maintenance; and to compare seagrass/chicken litter with lucerne hay and pasture for sheep production on a scale such as would be applicable to lot-feeding of sheep in the area of suthern Australia in case of short term feed scarcity. To approach this ta...
