Worm Castings last how long.....???
Here's some more info I've found on the topic......

I haven't heard anything about release rates for other mediums/conveyance methods but I have read that teas should be left to steep for 24 hours before application. The reason for that may be that worms coat their castings in polysaccharides and since those long chain carbohydrates are not soluable in water, they won't allow a great tea to be made right away.
A polysaccharide bond can be broken down by amylase<<<and there is a lot of that in urine. Urine also has a lot of nitrogen...
or you can just wait a while
Besides nitrogen, castings contain lots of other nutes. and they have growth hormones and vitamins. and they also act as good biocides against diseases and nematodes
There are some differences when it comes to exactly what nutes can be found in worm manure, just like there is for other manures. It can depend on the species of the worm and on what the worm ate.
here are some samples:
species of earthworm - Eisenia foetida
pH 7.40
Organic Carbon (%) 27.43
Total nitrogen (%) 0.60
Total phosphate (%) 1.34
Total potassium (%) 0.40
C: N ratio 45.70
species of earthworm - Perionyx excavatus
pH 7.00
Organic Carbon (%) 30.31
Total nitrogen (%) 0.66
Total phosphate (%) 1.93
Total potassium (%) 0.42
C: N ratio 45.90
red worm castings produced from dairy manure; there are some multiple results and these are from separate tests of the same farmyard
pH 6.3
EC (mmho/cm) 5.92
C:N ratio 14:1
Moisture 67%
Total N (TKN) 2.92% 3.21%
C: N ratio 45.70 45.90
Nitrate N (ppm) 630 420
Ammonium N (ppm) <37 35
Organic carbon (%) 40.2 49
Total P (%) 1.1 1.1
P2O5 (%) 0.187
Total K (%) 1.5
K2O (%) 0.434
Calcium (%) 3.1
Magnesium (%) 0.7
Sodium (%) 0.3
Iron (%) 0.3
Manganese (ppm) 295
Copper (ppm) 123
Zinc (ppm) 357
Boron (ppm) 75FYM
non-specified kind of worm
Nutrient - Percentage
Nitrogen 2
Phosphorus 1.2
Potassium 1
Sulphur 0.4
Calcium 1.5
Magnesium 0.4
