Soil or Liquid Samples

This page explains the way to take a Soil or Liquid Sample which will be used for a biological assessment. Please follow the steps to ensure that the quality of the product being assessed is of the highest standard when we receive it.  

General tips for accurate results:

  • Take the samples when it is possible to ship them immediately, the same day.

  • Shipping should have a target delivery timeframe of 1-2 business days.

  • Wash your hands well or put on clean gloves before handling the sample material, and between handling different samples.

  • Keep the samples out of extreme heat or cold as this risks killing the organisms we seek to measure. Aim to keep samples at room temperature or slightly cooler. If shipping during the height of summer heat, a cooler pack may be added to your box with padding so that it is not in direct contact with samples.

  • Tools required for sampling: unused large zipper-type plastic bags or a clean container, a shovel and/or soil core, a permanent marker.

  • Please ensure to place samples in a box or padded bag where they will not be compacted along the way.

  • For sending Liquids: this is directly from the Australia Post regulations for Posting Liquids:

“The packaging for liquids that are non-dangerous goods must comprise:

  • a leak-proof primary container made of glass, metal, plastic or similar material

  • a strong outer box made of metal, wood, strong plastic or strong corrugated cardboard with a lid that cannot easily work loose.

  • an absorbent material, such as cotton wool, to be placed between the primary container and the outer container and of sufficient quantity to absorb all liquid if the primary container fails.

Dangerous and prohibited goods and packaging guide – January 2020 • Section 10 – Preparation and packaging 42. If the primary container is a can with a friction-fitted lid, the lid must be spot soldered to the can in at least four spots, evenly spaced around the lid."

Soil / Compost Sampling Step-by-Step

 

1. Identify the sample area(s).

There may be multiple samples to take if there are several different conditions on your land, or various areas of interest. Ex: If part of your crop is healthy, and another part is diseased, those would be two separate sample areas. Ex. If you have several compost piles, each pile would be its own individual sample. If conditions within each pile are not homogenous, then you can separate these different areas of one pile into two different samples. 

Complete the following steps 2-5 for each separate soil sample area, or compost pile.


2.  Collect your sample.

For Compost:

For each compost sample, reach 6-12 inches into your compost pile, or halfway between top and bottom to take a handful. Repeat 3-5 times, taking each handful from different locations in the sample area. 

For Soil:

Before taking a soil core, remove any debris or organic matter sitting on top of the soil. Take soil cores from 5-10 locations within your identified sample area. When making your selection, consider the following: 

  • If your analysis is related to a particular plant/crop of interest, take soil cores from the root zone of the plant. Plants should be selected at random throughout the sample area. Ex: To test the soil ecology of a corn crop, pull soil cores from areas where the roots of the corn are present.

  • If you are sampling soil around trees, take samples from midway between the edge of the canopy and the tree trunk, at the appropriate root zone depth. If the root zone is located in the first 3-4” of soil, start sample from the top of the soil (insert corer into soil, take soil from the top 1-4”.) If the root zone is deeper, insert corer to the appropriate level and take 4” at that level (so if the root zone starts at 4” deep, take a soil core from 4-8” of depth.)

  • If testing for the general state of microbial health within a sample area, but with no particular plant of interest in mind, select 5-10 random locations across the area.

3. Compile your sample.

Compile 5-10 soil cores or 3-5 compost handfuls taken from a single sample area into one bag, creating a composite sample. Leave air space in the bag to allow oxygen for soil organisms. The minimum amount of sample material we require is 500g (~2 cups)

 

4. Label.

Once the sample is taken, please write the following information on the outside of the sample bag. Do not place a note inside the sample bag as this may affect results:

  • A sample number (simply: #1, #2, #3 etc)

  • Sample type: compost, soil, or other

  • The date and time the sample was taken

 

5. Mail your samples.

Send samples on the same day to the following address. If using Australia Post, please be aware it could take 3 days to arrive (this timeframe may alter your results). If using a courier, ensure it is same day delivery to our door and not the local post office as this will delay the arrival time. We suggest sending samples on Monday on a week with no public holidays, to prevent any delays in delivery.

Tea / Extract Sampling Step-by-Step

 

1. Identify the tea or extract to be sampled.​

There may be multiple samples to take if there are several different teas or extracts. Ensure the tea has finished brewing for 24hr (this is when most of the oxygen is being used).

 

2. Collect the tea or extract.

Buy a fresh small bottle of “spring water”. Empty the contents into a glass by pouring into a glass and not drinking from the bottle (as this is put unwanted microbes in the bottle). Ensure the “spring water” has no additives or flavours.

Pour your tea or extract into the empty water bottle to 1/3 full.

Cap the bottle and wrap with duct tape.

 

3. Label.

Once the sample is taken, please write the following information on the outside of the sample. This can also be on the outside of a ziplock type bag to prevent leaking during post.:

  • A sample number (simply: #1, #2, #3 etc)

  • Sample type: tea or extract

  • The date and time the sample was taken

 

4. Mail your samples.

Please follow Australia Post guidelines for sending liquids. Send samples on the same day to the following address. If using Australia Post, please be aware it could take 3 days to arrive (this timeframe may alter your results). If using a courier, ensure it is same day delivery to our door and not the local post office as this will delay the arrival time.
