Controlled release granules have two main types. One is controlled by moisture availability (which can be problematical if we have showery weather as all the nutrients are leached out in one go!)

The other type is temeperature controlled. If you imagine tiny golf balls filled with fertiliser which leach out from the 'dimples' as the temperature rises but if it's too cold retains the nurients as it contracts.
In my opinion the second type is better and can control release of fertiliser for up to 6 months! Cool

My white onions that I was so impressed with last year have arrived so will be planted along with the yellow and red onions when I prepare the beds for them. Smile

I really shouldn' ttell you this but before I retired I was Head Groundsman at a University. As such I had a sizeable budget and ordered tonnes and tonnes of  fertiliser and grass seed mainly for football and rugby pitches. I was getting sick of the short term gain from conventional fetiliser and the constant need to get manpower to spread it. After much experimentation I finally narowed it it down to a twice yearly application of temperature controlled release fertiliser (Spring & Summer with Autumn & winter spread later in the season) The Summer fert was higher in Nitrogen than the Winter stuff and each gave a constant feed for six months.
When I left the Uni, I didn't realise I had a bag of Autumn fertiliser left in the back of the car and this single bag has sustined me at the allotment ever since! Blush Its so long ago I honestly can't remember which brand it was,but it was suppied in 20Kg bags only.

My concern with controlled release fertilisers is the polymers they coat the granules with not being biodegradable. I've found empty blue plastic shells in pots, and the last time I bought compost with blue granules in was over 3 years ago.

We did tests and found the stuff we used totally degraded? We used it for many years and I can't say I ever found any 'shells' remaining in the substrate.We did add 100 tonne of Messingham sports sand to each pitch each year as a topdressing so thats maybe why I never found any spent fertiliser shells? I have seen slow release fertiliser with masive granular size from Sierrablen (which we tried and discarded) but ours were micro grans and not in the fluerecent colours I have seen sold in GC's. Cry
I like to grow organic but it isn't feasible on Sports pitches? (not then ,anyway) We once tried organic chicken manure based pellets on the cricket outfield. It was great until we had a shower of rain where all the criceters came off the oval holding there noses! Big Grin We had rat problems in storage with it as well! Sick

When I left my last job, the organisation was being shut down so we all left with the contents of the stationery cupboard and various other souvenirs. I have the name plaque from my office door somewhere - should put it on the shed .Big Grin

I have a terrible habit of making it all the way home with jelly (lubricant) and suppositories or enemas in my pocket. Of course I take them back again, but it sometimes takes a while before I remember. It's resulted in a couple of raised eyebrows when my parents have helped me to move in the past Big Grin
