Once you have signed up for the project you will get sent a kit, including borage seeds, pH meter, cotton strip and pre-paid envelopes that you can send samples of soil to the Royal Agricultural University’s soil science laboratories.
Here, the soil is weighed and some chemistry components are tested, including pH, organic matter content, total carbon, total nitrogen and some micronutrients/heavy metals.
Soil is weighed and oven dried before it is milled.
These initial soil samples are useful as they provide a baseline measurement of the soil that is being used. How this soil changes over time as plants are actively growing in it will vary depending on plant growth, biological activity and climate.
