What tests are the best for soil?
When you arrange your soil test through BioAg, the soil samples are tested at either the Southern Cross University’s Environmental Analysis Laboratory (EAL) in Lismore NSW or at Eurofins APAL in Adelaide.
Both are independent, accredited laboratories. Independent being the key word, and therefore not associated with any agricultural product manufactures or distributors. Both have a strong focus on quality of data and accuracy.
EAL developed an Australian version of the Albrecht/Reams soil test (RA-PACK-001) suitable for Australian soil types. It includes:
• standard Australian testing for exchangeable cations (Ca, Mg, K, Na, H, Al)
• plant available micronutrients (Fe, Cu, Zn, Mn, B, Si)
• phosphorus tests (Bray 1, Bray 2, Colwell)
• nutrients (Nitrate, Ammonium, Sulphur)
• ‘Reams’ dilute Morgan extract for determining soluble nutrients (Ca, Mg, K, P)
• pH, electrical conductivity, basic colour, basic texture, total LECO carbon and total LECO nitrogen.
An extended suite of tests is also available (RA-PACK-02) to give additional information on nutrients adsorbed to soil particles and organic matter. Testing includes:
• RA-PACK-01 tests
• ‘Pseudo-totals’ extracted with concentrated acids (Ca, Mg, K, Na, S, Fe, Cu, Zn, Mn, B, Al, Si, P, Co, Mo and Se).
BioAg agronomists can help with sampling, submitting the samples for analysis and interpreting the results.
