First ever Vermicast Harvesting at UWIFoRT
On 11th August, 2022, with the generous contribution
of 1.5 Kg Tiger worms (Eisenia foetida)
from National Soil Services Centre, Thimphu, Ugyen Wangchuck Institute for
Forest Research and Training initiated Vermicomposting in the Nursery shed.
The earthworms were housed in a wooden tub of the dimension 2m*1m*0.5m
and fed with meticulously ground organic refuse that were carefully weighed each
time the worms were fed. Moisture content and temperature were vetted by the
nursery incharge on a regular basis.
On 27th January, 2023, the Institute made its first ever vermicast harvest that yielded four 25kg sacks of vermicast and hundreds of worm ova.
Worm castings contain five times more nitrogen, seven times
more phosphorus, and 11 times more potassium than ordinary soil, the main
minerals needed for plant growth (https://tpncorganic.com/product_details_38) accessed

We plan to further vermicomposting works and start breeding
worms in a separate chamber.
