Mineralization and nutrient release pattern of vermicast-sawdust mixed media with or without addition of Trichoderma viride.

A combination of vermicast and sawdust mixed medium is commonly used in horticulture, but the added benefit of microbial inoculation and mechanism of nutrient availability are unknown. This study was done to determine nutrient mineralization and nutrient release patterns of different combinations or...
