 Optional Extras

Grain Sampler ($450.00 + GST)


         DSC04136    DSC04137

 The grain sampler has 2 features. The first is the small holes (above), in the closed position allows grain pests to fall through and into the base cylinder. This provides easy inspection access to the silo for possible pest infestation.

Second, the grain sampler takes samples from four levels (below) in the silo. This provides quality checks of grain at each level and at what level, if any, pest invasion.

Nitrogen Kit ($70.00 + GST)



 The benefits of using nitrogen over phosphine include - nitrogen is a ready available source from the atomosphere, it is safe to use and unlike phosphine it has no withholding period.

The results from the initial trial on Doug and Leon Clarke's farm proved overwhelming - the system killed all the insects in the trial except one, which isn't found in Western Australia.

Ultimately the Clarke's were left with 1000 tonnes of insect and pesticide residue free wheat. "The beauty of that is if we put nitrogen gas in today and someone wants to buy my grain, then I can take it straight out again - there are no with holding periods." Doug said. Improved marketability - that's what we're hoping for.

Doug and Leon see that something has to change because "it's unsustainable to keep on fumigating weevils with phosphine."

 Silo pad preparation before Silo is delivered

Silos are to be installed on a level reinforced concrete pad of minimum 125mm thick, and recomended that they mature for 10 days. The recomended size is 600mm larger than the diameter of the silo ordered, allowing a 500mm gap between silos aids access to silo perimeter. The silos are bolted down using dynabolts, which we will provide and bolt the silo down for you on delivery.

Uneven or inadequte pads will result in silo damage. If the pad is not flat, the gap between the base ring and the pad should be packed with steel shims (@ $2.50 + GST each) under each leg.

Bird's Silos and Shelters will take no responsibility for damage caused by unsatisfactory pads.



Silos up to 900 bushel (one silo, no escort required) - $3.95 per km

Silos up to 900 bushel (two silos, no escort required) - $6.90 per km

Silos 1100 bushel plus (one silo, escort required) - $4.90 per km

Silos 1100 bushel plus (two silos, escort required) - $7.90 per km

Prices are one way excluding GST

Minimum delivery fee - $500.00 + GST
