Your soil test says everything’s fine. Your crop says otherwise. They can both be right.
A standard soil test is a chemistry test. It tells you how much of each nutrient is sitting in the soil — nitrogen, phosphorus, potassium, pH and so on.
That’s useful information.
But, this is a stock-take, not the full story.
It tells you what’s there.
It doesn’t tell you whether any of it is actually being made available to the plant.
This job belongs to the biology!
Nutrients don’t walk to the roots on their own. Microbes mineralise organic nitrogen into forms a plant can take up.
Fungi and bacteria help to prise open the loose phosphorus that’s chemically “present” but locked away in the soil.
Even though a soil can look well-stocked on paper, it still might be 'underfeeding' a crop - because the workforce that turns reserves into availability isn’t there in the numbers it needs.
That’s why a full picture of soil health has three legs, not one:
1) chemistry
2) physical structure, and
3) BIOLOGY
A chemistry test covers the first leg. It can’t see the third.
We assess and quantify the life in the soil, which is how we look at that third leg: counting and identifying the organisms actually present, so you can see whether the biology is there to cycle what the chemistry says you’ve got.
This is why we built to track that biology over time, not just once.
So when the chemistry looks right but the crop disagrees: have you checked who’s doing the work?
