With this approach, we could indicate their role in the soil food web [26]. For network analysis, a Spearman’s rank correlation approach was used to visualize the correlations between all individual members of the aggregated groups. All the positive correlations (p < 0.05) between groups ...
Earthworms redistribute organic materials within the soil, increase soil penetrability and, und certain conditions, influence ion transport in soils. Root
In research published this September, scientists found that earthworms may contribute to more than six percent of global grain production every year, because of their crucial role in soil ecosystems. Worms help to break down dead plant material, releasing nutrients plants need to grow, and their ...
