Dynamic Accumulators
Deep-rooted plants that mine nutrients from subsoil and make them available
What Are Dynamic Accumulators?
Dynamic accumulators are plants with deep tap roots or extensive root systems that access nutrients from deep in the soil profile. They concentrate these nutrients (phosphorus, potassium, calcium, magnesium, trace minerals) in their leaves and stems. When these plants are cut or die back, the nutrients become available in the topsoil for other plants. This is nutrient cycling at its finest.
Benefits
- Bring deep minerals to the surface without digging
- Improve topsoil fertility over time
- Break up compacted subsoil with powerful tap roots
- Provide nutrient-rich mulch and compost material
- Many accumulate specific minerals (comfrey = potassium, dandelion = copper)
Example Plants
Comfrey
Symphytum officinale
The king of dynamic accumulators. Accumulates potassium, calcium, phosphorus. Produces massive amounts of biomass. Can be cut 4-5 times per season for mulch.
Dandelion
Taraxacum officinale
Deep tap root mines minerals from 10+ feet down. Accumulates copper, potassium, calcium. Edible leaves and flowers. Self-seeds readily.
Chicory
Cichorium intybus
Tap root penetrates compacted soil. Accumulates potassium, calcium, phosphorus. Edible leaves and roots. Supports pollinators with blue flowers.
Yarrow
Achillea millefolium
Accumulates copper, phosphorus, potassium. Medicinal herb with pest-repelling properties. Attracts beneficial insects. Drought tolerant.
Stinging Nettle
Urtica dioica
Accumulates iron, calcium, nitrogen, trace minerals. Makes excellent compost activator and liquid fertilizer. Edible when cooked.

Implementation Tips
Cut accumulator plants 2-4 times yearly and use as mulch or compost
Plant around fruit trees and perennial vegetables
Make liquid fertilizer by fermenting accumulator leaves in water
Let roots remain in soil to decompose and create channels for water/air
Combine different accumulators to mine diverse mineral profiles
Use comfrey as a potassium-rich mulch for tomatoes and fruiting plants
