First, what is health?
The World Health Organisation finds it difficult to define human health, so how on earth are we supposed to define soil health.
Soil, like humans, are complex things, with lots of interconnected parts. Each part of the soil affects another. And, in the same way, improving soil, helps other things such as crop yield and the environment.
Google dictionary describes ‘health’ as:
The state of being free from illness or injury. E.g. “he was restored to health”
What texture does healthy soil have? Think sponge cake
So how would we describe injury-free soil?
Simplistically, this would be a soil that is full of happy organisms such as bacteria and worms, with a light and crumbly structure. I often describe soil like cake (which one shouldn’t eat too much if being healthy), but to continue the analogy, we are aiming for a Mary Berry sponge cake rather than flat and dense Mississippi mud pie.
Healthy soil is one that sustains and encourages life.
