Carbon Fertilizer Plus is a humic acid–based fertilizer for base application. Supplied in 25 kg bags; other packaging on request.
How humic substances work in soil
- Humic acid has a high cation exchange capacity, so it can hold ammonium and potassium ions in the root zone.
- Humic acid can help soil particles form aggregates and can help the soil hold water.
- As a weak acid with buffering capacity, humic acid can help moderate soil pH.
- Humic substances are part of soil organic matter and have been studied for their effects on soil microbial activity; results differ between soils and products.
How to use
