AND HOW UNDERSTANDING IT CAN MAKE GARDENING EASIER FOR YOU The Hidden Soil Food Web

The Soil Food Web

Benefits of a healthy Soil Food Web Captures, stores, and makes available essential plant nutrients. Especially nitrogen. Builds healthy soil structure that stores water and holds nutrients Provides natural disease prevention, protection, and suppression

It all starts with plants

How do plants use carbon for their benefit? Root exudates in the rhizosphere

The Soil Food Web

Bacteria Bacteria capture, store, and make nutrients available

Bacteria Bacteria are “fertilizer packets” for plants

Bacteria Bacteria build healthy soil structure

Importance of organic matter in soil

Other roles of bacteria Bacteria keep pathogens in check

Fungi Fungi are the primary decomposers

Fungi Mycorrhizal fungi provide nutrients, water, and disease protection for plants

Fungi Fungi are fertilizer packets

Protozoa

Benefits of Protozoa Protozoa are fertilizer spreaders Protozoa keep bacterial and fungal populations balanced

Nematodes Nematodes are fertilizer spreaders

The rest of the soil food web

Benefits of a healthy Soil Food Web Capture, store, and make available essential plant nutrients. Especially nitrogen. Build healthy soil structure that stores water and nutrients Natural disease prevention, protection, and suppression
