Overall guidelines:

Clean plastic bags should be used for sampling

Do not sample directly after spraying any chemicals

Sampling procedure:

• If possible avoid touching the leaves with bare hands to prevent any contamination

• Place 200-300grams in a clean plastic bag.

• Seal the bag

​

Please label all samples as descriptive as possible - includ sampling site and date

Samples must be sent to the laboratory within 1-2 days after sampling

Please note:

• Incorrect sampling procedures may lead to inaccurate results

• Leaf analysis takes 3-4 working days longer due to sample preparation before analysis can commence

Turn-around times for leaf analysis is 10-14 working days (including sample preparation)
