Professional Seed Sampling

Everyone samples regularly in daily life. For example, you can taste a delicious piece of melon on the market and then decide to buy a melon. Sampling is taking a decision based on limited information. It is impossible to taste all the melons!

During the Professional Seed Sampling course you will explore the different steps in the sampling process. You will be informed about all the important aspects when taking a sample. On completion of the course you will gain knowledge how to take a reliable representative sample according to the sampling process and the guidelines of e.g. NAL (Naktuinbouw Authorized Laboratories).
