Sample Submission Guide

Step 1 - Prepare Your Sample

Sampling

Mix properly before taking a sample. Take a couple of small samples from different spots of your batch and combine them to ensure a representative sample is sent to the lab. The lab can only analyse what is received whether this is representative of your entire batch or not.

Container

Ensure that the sample is in a suitable leak-tight container (tamper-proof if possible). Also, ensure that the container does not interact with the sample in any way (eg. sunlight or leaching impurities).

Amount of Sample

Please follow the link to "Test Panels Offered" for details on the minimum amount of sample required for analysis. If too little sample is submitted we will not be able to perform all the analysis. Note that the minimum amount of sample is not regarded as a representative sample of your batch or crop.

Step 2 - Sample Request Form
