I know it must be really hard without proper equipment to check the quality of vermicompost, but is there, still, another way to test the quality?
To me, this doesn't look like vermicompost at all. It feels like soil mixed with some white seeds-like stuff.
They were all black in the bag it came in and when I applied it as a topsoil and watered it, most of the "castings" went from black to light brown and pale yellow. Is this casting drying out in sun or it is some other cheap material? How do I know it is real worm casting?
