Here are some guidelines for what time of year and how frequently to do different soil tests. In the diagram below you can see on the right hand side we have two levels of frequency, Best and Good for each test. Best options require an increasing commitment in terms of total time, but also probably increase the quality of data you get out.
The main part of the diagram shows the 4 key tests to do, and other popular tests, and when it is possible to do each type of test throughout the year e.g you won’t find many earthworms in June because they have hibernated so we advise not to do the test then.
The main thing to consider is to build a schedule that you can repeat year after year, so best to stay simple.
It is very important to repeat your soil health measurements year after year at approximately the same time of year (weather dependent)
