FAS offers a wide range of agricultural soil testing options for many crops. While our research has focussed on sugarcane for over 60 years, we can now offer soil analysis for tea and coffee, maize, sub-tropical fruit, macadamias, grain crops, gardens, nurseries, golf courses and bowling greens.
Soil analysis is important to optimise production while efficiently managing your resources. Regular soil testing enables the early detection of harmful soil conditions such as acidity and salinity build-up, nutrient imbalances and overloads, and the depletion of organic matter. It is thus a cornerstone of sustainable farming.
What We Offer
pH (CaCl2), phosphorus, potassium, calcium, magnesium, sodium, exchangeable acidity (Al+H), total cations, acid saturation, exchangeable sodium, zinc, copper, manganese, sulphur and volume weight. Estimates of clay and organic matter, potential nitrogen volatilisation, nitrogen mineralisation and reserve potassium.
(Fertiliser recommendations for other crops is given on request.)

Sampling Procedures (All Crops)
For routine topsoil analyses and fertiliser recommendations, samples should be collected using a Beater auger. Use of this auger ensures that a constant sampling depth is maintained (20 cm for sugarcane; 15 cm for most other crops) and allows for easy collection of a large number of subsamples. If interested please download our soil submission form.
Recommended sampling procedure:
If the field consists of two distinctly different soil types, or only parts of the field have received large amounts of, for example, filtercake, a separate sample should be submitted from each section.
The subsamples should be taken in a zigzag pattern across the field. For ratoon crops, eight interrow subsamples should be collected for every one sample on the row.
