However, the SRP keeps the nitrogen in the soil mix rather than allowing it to float away as ammonia gas.
It also allows the calcium to “stick” to the soil mix instead of leaching out due to electromagnetic proper-
ties of the SRP.
Powdered soft rock phosphate is great in mixes that contain lime
I use both granular rock phosphate and powdered SRP in my soil mixes, and SRP is going to be a very
important part of yours as well. The microbeasties seriously love their nitrogen and calcium. I'll say that
again: the microbeasties inside your soil mix, the little living things that make TLO growing work abso-
lutelylovenitrogenandcalcium.Youwoulddowelltotattoothatontheinsideofyoureyelidssoyou'llbe
reminded ofit even when you're asleep. Iuse rock phosphate as well because Irecycle mysoil mix. Ifyou
are not planning on recycling your soil mix, then there is no reason I know of that granular rock phosphate
should be used.

It possesses boron and silicon, to name just two of the 60 or so trace elements it has. I love this stuff and I
try and get it in the smallest particle size possible. Micronized is my favorite grade of this, and as you will
see in my custom soil mixes, a little bit of this goes a long way in container growing.
REV'S TIP
I get my SRP from a place called Nitron Industries online, 5 pounds at a time.
5 pounds will last me, with a personal size garden, probably 5 years or longer—and it is a little ex-
pensive. I think it costs me as much to have it sent as the product itself. Anyway, my point is you
want some of this—it's fantastic stuff full of good things for a living soil mix.
