Eco garden products are one of the most marketing-heavy categories in the natural home market. Mycorrhizal inoculants, compost activators, seaweed fertilisers, biochar. The claims are often big and the evidence is often thin.
This section evaluates eco garden products through soil biology and biogeochemistry. I look at what the chemistry and the field evidence actually show behind the most popular soil health product claims.
Healthy soil is genuinely complex. Carbon cycling, nitrogen transformation, microbial communities, fungal networks. The science behind soil health is real and fascinating. The problem is that many eco garden products borrow that scientific language without delivering what the label implies.
Whether a mycorrhizal inoculant product actually contains viable fungal propagules. Whether a compost activator does anything a well managed compost pile would not do on its own. Whether biochar products justify their cost with real soil chemistry benefits. This section works through the evidence.
