A farm level assessment of a novel drought tolerant forage:Tedera (Bituminaria bituminosa C.H.Stirt var. albomarginata). AgEcon
Finlayson, John D.; Real, Daniel; Nordblom, Thomas L.; Revell, Clinton; Ewing, Michael A.; Kingwell, Ross S..
Tedera (Bituminaria bituminosa C.H.Stirt var. albomarginata) is a drought tolerant perennial legume originating in the Canary Islands. This study evaluates the potential role and value of tedera in dryland mixed crop and sheep production systems in southern Australia. Regional variants of the bio-economic model MIDAS are used to assess tedera in farming systems at two locations. The analysis considers the quantity and quality of feed produced by tedera, the ability of other forages to complement or substitute for tedera and its impact on meat versus wool-producing sheep flocks. The results indicate that tedera offers the potential to increase farm profits by up to 26% and be grown on ~28% of a low rainfall mixed enterprise farm. On a high rainfall mixed...

Modelling the mitigation mix: faecal microbes, economic constraints and sustainable land management AgEcon
Butler, Allan J.; Oliver, David; Chadwick, Dave; Fish, Rob; Winter, Michael; Hodgson, Chris; Heathwaite, Louise.
Conventional livestock farming provides consumers with cheap and reliable sources of milk and meat. Yet the inevitable by-product, i.e. livestock faecal matter, represents a potential source of pathogenic microorganisms. This paper applies the Faecal Indicator Organisms Costing Assessment Tool (FIOCAT), which was designed as part of the RELU project ‘sustainable and holistic food chains for recycling livestock waste to land’, to examine the costs associated with mitigation methods that may inhibit pathogenic transfers to water. FIO-CAT is comprised of three interrelated models: the economic dairy management (EDM) model, the farm business survey (FBS) model and the manure, infrastructure and environment (MIE) model. Specifically, it models dairy, and cattle...
