Parasites<br />

Sheep can recycle their own parasites but they can also<br />

pick them up from wild animals. Hares and rabbits may be<br />

a vector for transmission of worms and other parasites,<br />

according to research being conducted by a Brazilian<br />

student as part of her post-graduate Veterinary Science<br />

degree.<br />

Late crop sowing warning<br />

Wet paddocks have virtually drowned any hope of<br />

traditional winter sowing in some high rainfall districts this<br />

year and in some instances spring sowing is emerging as<br />

a real possibility.<br />

Before sowing, croppers need to carefully consider a<br />

number of factors and risks according to an article in ‗The<br />

Break‘ newsletter by Ash Wallace from the Department of<br />

Primary Industries (DPI).<br />

Mr Wallace said one common question related to the<br />

expected yield loss from sowing in spring.<br />

―While actual cases of spring sowing in Victoria have been<br />

limited in recent dry years, scientists at DPI Hamilton have<br />

used the APSIM crop model to predict potential yields for<br />

a wide range of sowing times across a number of sites in<br />

the South West based on 120 years of climate data,‖ he<br />

said.<br />

―The APSIM model is driven by interactions between<br />

climate, physical soil characteristics, soil moisture, soil<br />

nitrogen, crop type and variety. It doesn't account for<br />

other nutritional<br />

disorders, pests, diseases or stress from temperature<br />

extremes.<br />

Mr Wallace said one of the key risks for such late sowing<br />

was heat stress around flowering and the APSIM outputs<br />

help to illustrate this point by predicting time of flowering<br />

for different sowing dates and varieties which can then be<br />

related to the risk of heat stress at a given time.<br />

―The results suggested that in high rainfall areas yield<br />

potential for spring sown crops would be considered quite<br />

respectable for conventionally sown crops in lower rainfall<br />

areas.<br />

―However the risk of heat stress at flowering is quite high<br />

and may affect both yield and quality. This can be<br />

reduced by sowing early and choosing early maturing<br />

varieties.<br />

―While current soil moisture levels are good, there is still<br />

the risk of a dry spring and early summer, and this<br />

increases as you move closer to medium rainfall areas.<br />

―This could be managed by grazing the crop or cutting<br />

them for hay if sufficient bulk is produced from current<br />

moisture levels.<br />

―There are also logistical, nutritional, pest, disease and<br />

marketing considerations in the spring sowing decisionmaking<br />

process.<br />

―While the wet winter has been frustrating and limiting for<br />

some high rainfall croppers, spring sowing presents as an<br />

opportunity for some.<br />

―Before you sow it is vital to seek further information and<br />

conduct a rigorous assessment of the risks involved.‖<br />

Funding available to voluntary environmental<br />

groups<br />

Landcare Australia and Be Natural are pleased to<br />

launch a $125,000 grants program that will provide<br />

funding to voluntary environmental community groups<br />

across Australia. The grants program will enable<br />

groups to continue work in tackling local environmental<br />

issues by providing funding to help with the<br />

continuation of on-going projects.<br />

The Be Natural Landcare grants program provides<br />

grants of up to $5000 to 25 local groups to help with<br />

projects which have not received funding in the last 12<br />

months. The program also encourages groups to find<br />

innovative ways of attracting more volunteers.<br />

Tractor safety needs more focus<br />

WorkSafe Victoria is warning farmers to take more<br />

care around tractors after a vegetable farmer on a<br />

farm at Pearcedale escaped with his life after the<br />

second serious incident involving a tractor in Victoria<br />

in a matter of days. The tractor was moving slowly<br />

when the 49-year-old stepped off to check seed<br />

dispensers, but it appears he slipped on the step and<br />

was run over by the tractor which weighed nearly three<br />

tonnes.<br />

Rural communities to benefit from Carbon<br />

Farming Initiative<br />

Farmers will be able to access international and<br />

domestic carbon markets under legislation passed by<br />

Parliament to establish a regulated carbon offsets<br />

market in Australia.<br />

Increasing carbon in soils or vegetation, or lowering<br />

emissions from livestock or fertiliser use creates the<br />

potential to generate carbon credits for landholders<br />

that can be sold to companies who wish to offset their<br />

carbon pollution.<br />

More carbon farming possibilities are being<br />

investigated including manure management, fertiliser<br />

management, savanna burning and managing<br />

methane from livestock.<br />

Later this year the Administrator for the Carbon<br />

Farming Initiative will begin operating and eligible<br />

projects can backdate credits to July 1, 2010.<br />
