Effect of Californian Red Worm (Eisenia foetida) on the Nutrient Dynamics of a Mixture of Semicomposted Materials

The efficiency of composting processes with and without the addition of Californian red worms (Eisenia foetida) was evaluated, using manure of dairy cows to generate organic fertilizer. Several parameters were assessed as physio-chemical indicators of maturity, such as temperature, pH, C/N ratio, ph...
