Apal Agricultural Laboratory

Other Testing Services

APAL offers many other laboratory services: Please refer to our service guide price list


APAL can analyse your compost samples. Composts can be used as a source of nutrition and/or soil amendment and are typically combined with conventional fertiliser sources to improve production. However, considerable variations associated with the compost manufacturing process make testing particularly important to understand the composition of your compost. This will then enable you to budget the nutrition for yield outcomes.

Only dry or composted materials are accepted by APAL. We are unable to test raw or uncomposted manure or untreated effluent. If in doubt, give us a call before sending us your samples. If you have raw manure or effluent we can discuss optioins with one of our partner laboratories.

APAL can analyse your lime, dolomite and gypsum samples for calcium, magnesium and sulphur content.

With gypsum analysis, the percentage purity is then derived from the sulphur analysis. As lime and dolomite also have a sieve analysis, the report includes both Total Neutralising Value (TNV) and Effective Neutralising Value (ENV).

The APAL report includes comments comparing the sample with the desired mineral content and test parameters for the various industry accepted grades for soil amendments.

Grain Mineral Testing

APAL can analyse your grain samples to test the nutritional value of your grain, and can also estimate nutrient removals for that particular crop. Analysing the mineral content of grain can also assist you with determining the minerals available to your animals consuming this grain diet. This will be based on your animals’ requirements and the mineral concentration in your grain.

Feed Testing

APAL can accurately assess the quality of your feed before you distribute it, buy it or sell it. We arrange testing through a specialist sub-contractor, using Near Infrared (NIR) technology or classical wet chemical analysis for hay, silage, pasture and grain feeds. Our analysis will determine how well your feed meets the nutritional requirements of your livestock and help you make informed decisions on feed rations and budgeting for feed gaps.

Soil Biological

APAL offers an exclusive low-cost science based microbial activity test to Australian farmers. Adelaide’s Creation Innovation and Forestry (CIAAF) Microbial Activity Test is ideal if you want a broad, single indicator of microbial activity in your soil.

CIAAF measures CO2 evolved from a sample over a given time by digital chromatograph to calculate the amount of microbial activity (measured as microbial respiration). The greater the amount of CO2 evolved over a given period the higher the amount of microbial activity. There is a very good correlation between CO2 evolution from soils and other materials, such as compost, and microbial activity.

Heavy Metals in Soil

Did you know APAL also tests for heavy metals in soils? Our analysis includes:

  • Antimony
  • Arsenic
  • Barium
  • Beryllium
  • Boron
  • Cadmium
  • Cobalt
  • Chromium
  • Copper
  • Manganese
  • Nickel
  • Molybdenum
  • Lead
  • Selenium
  • Tin
  • Vanadium
  • Zinc
  • Mercury (to be specified).

These metals are generally accepted as potential contaminants of soil and produce. Excess quantities of these heavy metals can impact human and animal health.

Pesticide Residues

Test samples sent to APAL are analysed for specific pesticides in either the OrganoChlorine (OC) or OrganoPhosphate (OP) categories. These include:


  • Aldrin
  • Alpha – BHC
  • Alpha – Endosulphan Beta – BHC
  • Beta – Endosulphan
  • Chlordane (a, g, oxy-Chlordane)
  • DDD
  • DDT
  • Delta – BHC
  • Dieldrin
  • Endosulphan Sulphate
  • Endrin
  • Endrin Aldehyde
  • Heptachlor
  • Heptachlorepoxide
  • Hexachlorobenzene
  • Lindane (gamma BHC)
  • Mehtoxychlor


  • Chlorpyrifos
  • Chlorpyrifos Methyl
  • Diazinon
  • Ethion
  • Fenitrothion
  • Fenthion
  • Malathion
  • Parathion
  • Parathion Methyl
  • Ronnel

In addition to heavy metals, these pesticides are generally accepted as potential contaminants of soil and produce and can also negatively impact human and animal health if present in excess quantities.
