Field Sampling Guide
A step-by-step protocol for collecting soil, compost and liquid (extract, tea or water) samples for biology testing, so the sample tells you something true about the ground it came from.
- Before you go: define the question, map the area, and choose sample locations at random from a numbered grid.
- Collecting: how to take soil cores, compost grabs and liquid samples, and how to avoid contamination.
- Handling: how much to collect, how full to fill the bag, labeling, storage and timing, when to sample, and how many samples.
- A field record to fill in at the site, a before-you-leave checklist, and a short glossary.
