The percentages of nutrients in these is so low that they are more accurately thought of as supplements. Otherwise they are both beneficial to plants. I use worm castings in every soil mix that I make for my own use.
A year-long study out here in commercial orchards has shown that worm castings applied topically
alone are no better than topically applying composted mulch alone. This is significant because worm castings cost 20 times more than composted mulch. Another find of interest to homeowners and perhaps no surprise to many of you: the best scenario by far was topical worm castings covered with a 3-4 inch layer of composted mulch.
The "composted mulch" in the study was produced by first "cooking" enormous piles of shredded greenery clippings for 90+ days, then using mechanized sorters to produce several grades of products. The composted mulch is the 1-inch screened material.
