  1. 1. The Fertiliser Action Plan using best practice fertiliser management for industry and environmental benefits Supported by WA Government, Western Dairy, WA Farmers, PGA, Fertiliser Industry Association, and …
  2. 2. What is Fertiliser Action Plan (FAP)? • FAP then: – phase out of highly water soluble P fertilisers • FAP now: 1. regulated phosphorus content in domestic use fertilisers; 2. ‘best practice’ management of commercial use fertilisers; • fostering economic benefits for farmers through improved nutrient management and achieving environmental benefits • based on industry self regulation around best practice and reduction in bureaucracy 2. enhanced uptake of soil amendments.
  3. 3. Providing the best advice for individual situations • Fertiliser users will get best advice from Fertcare accredited advisers (major company reps accredited) • Aim is to apply phosphorus where profitable – reduce use where it is not profitable – Farmers will use P more efficiently

  7. 7. Influence of pH on nutrient availability
  8. 8. Soil acidity
  9. 9. Potassium and Sulphur deficiency $ wasted on P based fertilisers when it could be spent on other deficient elements 45% also require lime
  10. 10. Fertilised independently of soil test 56% have high P status Soil test results ignored $ wasted LowHigh Plant response
  11. 11. Fertcare - Built in QA • Fertiliser Industry Federation of Australia has Fertcare program. • Fertcare involves rigorous training and accreditation system • Fertcare Accredited Advisers are independently assessed and audited. • Fertcare advisers bound by rules defining critical P and P retention levels
  12. 12. • Advice must fit with best management guidelines • Guidelines developed by industry (fertiliser companies and farmer bodies) on the basis of good science and years of WA trial work • Advice can only be given on the basis of soil/tissue tests
  13. 13. Broad support New FAP direction backed by: • local and national science (X years trials on Coastal Plain in WA) • Industry (fertiliser companies and farmer industry bodies ie Western Dairy) • Government – Dept. Agriculture and Food, Dept Environment and Dept. Water
  14. 14. Firsthand experience: Ken MacLeay, Blackrock Angus
  15. 15. Blackrock Angus Located at Vasse 380ha 300 breeders 80 bulls Traditional application of fertilizer after soil testing of approx 200kg/ha in autumn Spring supplement to hay paddocks to 200kg/ha Lime application 2.5t/ha every seven years Fertilizer expense represented our biggest direct cost after labour/drawings
  16. 16. Blackrock Angus Invited to participate in Fertilizer Management Plan (Nutrient Management Systems) 08/09 One of the best programs we have been involved in. Why? Gave me a better understanding of my fertiliser practise including the latest recommendations for P relative to PRI , and saved $$$$$.

  19. 19. Blackrock Angus For the last two seasons 09 and 10 fertilizer applications have been reduced dramatically. Current recommendations suggest application rates from zero to 70kg/ha are adequate. The savings have more than compensated for doubling annual lime application to 300t. This has resulted in big savings with no loss of production.

  21. 21. Soil testing 2010
  22. 22. 2010 program overview • 835 samples from 31 farms • Average of 27 samples per farm • Range from 3 to 89 samples per farm • As of today, we have results back for 785 samples
  23. 23. High P status and other deficiencies
  24. 24. See Neroli for a SPANA
  25. 25. Summary • 835 samples from 31 farms – Beef in Peel Harvey, Dairy in Geographe • 87% have pH<5.5 • 65% have low to marginal K, 20% low K • 61% have high P status95 – increases to 91% high P status at 80% production – most high P for higher PBI soils – 52% have high P and low pH – 31% have high P and low K – 28% have high P, low K and low pH • Maps are a big hit
