Earthworms' Contribution to Global Food Production
Earthworms' Contribution to Global Food Production
Earthworms play a crucial role in global food production, contributing to a significant portion of the annual harvest. The study estimates that their impact is comparable to the production of a major agricultural power, like Russia.
How Earthworms Improve Soil Health
How Earthworms Improve Soil Health
Earthworms improve soil health by creating tunnels that loosen and aerate the soil, allowing water to drain and be stored underground. They also churn organic matter making nutrients more available to plants resulting in healthy growth.

Study Notes
Earthworm Impact on Plant Growth
-
Earthworms significantly enhance soil, boosting global food production by an estimated 6.5% (or 140 million tons annually). This is comparable to Russia's annual grain harvest.
-
A Colorado State University (CSU) study analyzed earthworm populations, soil properties, and crop yields globally, focusing on rice, maize, wheat, barley, soybeans, and peas.
-
The study found a substantial positive impact in developing countries, increasing grain yields by 10% in Sub-Saharan Africa and 8% in Latin America. This suggests a correlation with limited chemical inputs such as fertilizer and pesticides and increased reliance on organic matter.
-
Earthworms improve soil by creating channels, enhancing aeration and water drainage, and churning organic matter, making nutrients more accessible to plants.
Earthworm Resistance to Microplastics
-
Separate research at Japan's Nankai University showed that earthworms can protect plants from microplastic pollution.
-
Tomato plants exposed to microplastics thrived when earthworms were present. This suggests that earthworms help boost plant immune systems.
-
Additionally, the presence of earthworms repelled common insects that feed on plants.
