Grain Cleaning
Grading of grain based on size, length, and specific gravity. Triple cleaning process ensures that there are very few foreign seeds that cannot be removed
Certified Seed
Registered shed capable of processing certified seed to international standards (ISTA).
Seed Dressings
Fully automated seed coating facility capable of packing 750 tonne per week. Coorow Seeds is capable of delivering grain in bulk, bulkbags and small bags.
Scarifying
Scarifying machine which is capable of enhancing the germination of hard seeded species.
De-Hulling
De-hulling machine which removes hulls from the grain.
Millling
Hammer mill capable of milling to customer specifications.
Gravity Grading Information
What is Gravity Grading?
- Gravity Grading is based on a really simple principle of gravity, the heavier the seed, the better the germination rate, vigor and yield rate of the seed.
- The gravity grading table plays an important role in separation of seed by its weight in the grading process.
- Our state of the art Gravity Grading machine ensure that the seed segregation will reach optimum quality and quality of resulted seed at highest achievable level.
Why Gravity Grade?
- Studies have shown that seed size and density effects the emergence rates of a crop., the larger the seed the faster the emergence and the higher number of seedlings emerge.
- This is vital in any commercial farming enterprise, because every seed costs money to plant. Every seed that doesn’t emerge costs money in planting, fertiliser, herbicides and pesticides and at the end of the season there is no seed for next season.
- More dense seed, especially when sown at optimal rates, is more resilient.
- When clean seed is planted it is not competing against weeds, it is healthy and is less likely to spread disease throughout the crop.
- Dense seed is more robust, allowing it to survive climatic events and has more energy to outcompete any weeds already in the paddock.
Advantage of cleaned harvest grain
- Storing grain with contaminants reduces the seed viability for the coming season. Dirt and other plant material can cause mould in stored grain.
- Research from the Department of Agriculture WA has shown that wild radish seeds release toxins during storage that renders surrounding seed inert.
- Storing grain without first grading and treating it leaves the grain susceptible to infection and to pest infestations, lowering yield when planted.
- Seed dressing can protect seed from insects and disease in storage.
- Gravity grading typically removes 10% of every load, including all weed seeds.
Being able to put clean, dressed grain straight into silos is a stress-free practice to be ready for seeding next year.
