This is one of two 176.7 µha worm plots under cultivation.
Full disclosure: This worm farming project has been a bitter disappointment. It seems the YOSJ staff are - so far - utterly incompetent worm farmers. But we remain undaunted and will bash on ahead in the face of adversity!
Note: There are plenty of suitably sized (if you happen to be a worm) holes in the farm underground.
