Plant Sampling Instructions
APAL's highly cost-effective and selective monitoring tool makes it easy to maintain plant health and optimise crop and pasture production.

Tips for sampling

  • Sample the correct part of the plant at the correct growth stage
  • Always wear gloves to avoid contamination
  • Regular tests build better profile
  • Be consistent in obtaining your representative sample, sample plants of similar vigour, variety, size and age
  • Sample early in the week; if storing samples over the weekend, dry or refrigerate
  • Use stainless steel cutting implements

Things to avoid when sampling

  • Spoiled, diseased, insect damaged, senescing or dead plant tissue
  • Unusual areas in the paddock which can include poorly drained soils, sheep camps, headlands etc
  • Areas of crops/pastures in the immediate vicinity of trees
  • Don’t sample plants under moisture stress and avoid waterlogging
  • Plants growing in dung or urine patches
  • Sampling soon after soil or foliar fertiliser application
  • Contamination from dust, soil, sprays, fertilisers and your hands (Always wear gloves to avoid contamination
  • Avoid touching fenceposts or any other object that may contaminate your sample
  • Plastic bags. Instead, use APAL’s paper bags

How to take the sample

  • Review your required tests. If guidance is required consult APAL or your local agronomist
  • Determine an appropriate sampling plan
  • Ensure a representative sample is obtained
  • Avoid unusual areas listed above
  • When troubleshooting, take samples from good and poor growth areas for comparison
  • Ensure the correct part of the plant is sampled
  • Collect the desired amount of leaves or petioles (generally aim to fill 1/2 to 2/3 APAL's plant tissue bags)
