I keep reading about 5-10-10 fertilisers being good for root vegetables (trying to grow swede/rutabagas), but I can't seem to actually find any available? Or maybe they are and I'm just being dumb. Could someone take a look at some Australian stores for me (Bunnings.com.au is the main garden store here) and link me to something suitable? The best I can find is this which doesn't seem to have any nitrogen or potassium at all? Don't I want something with all three but in the right ratio? Should I use a regular all rounder fertiliser AND this to balance it out? I'm just afraid of killing my young swedes by giving them the wrong thing.
I'm developing a pretty large new garden area, as well as several smaller ones from a weedy, pasture-like area. This is the first time trying it, but I'm using Steve Soloman's Complete Organic Fertilizer recipe. This is it, copied from a webpage:
3 quarts oil seed meal such as soybean meal, cottonseed meal or canola seed meal or 1 1/2 quarts feather meal or fish meal (smelly)
or, the very best combination is probably 2 quarts oil seed meal, 1 pint feather meal and 1 pint fish meal
1 quart soft or colloidal rock phosphate (the best choice by far) or bone meal
1 quart kelp meal and/or 1 pint Azomite (for trace minerals) (And/or apply liquid kelp every 2 weeks as a foliar throughout the season.)
Add lime: choose one of these two options:
If you garden where the land originally grew a forest, add these two:
1 pint agricultural limestone, 100# (fine grind) and
1 pint agricultural gypsum;
or if you garden where the land originally grew prairie grass or is a desert add:
1 quart agricultural gypsum
If you do not live in Cascadia, add 1/3 cup potassium sulfate.
The following last four items are optional:
1 teaspoon laundry borax or a smaller quantity of Solubor (1/2 gm actual boron)
1 1/2 teaspoons zinc sulfate
2 teaspoons manganese sulfate
1 teaspoon copper sulfate
Mix all ingredients are very thoroughly before spreading.
I'm using alfalfa meal in place of the seed meal, and this summer I am going to dry a bunch of comfrey from my plants for use in the mix next year in it's place. I also have Sea-90 that I will use alternately with the Azomite.

That amount is to cover 100 sq ft. I haven't figured out the cost yet. I think all total, I have approximately 6000 sq ft of garden space. It will take some time to figure out totals because of course the bags are sold by weight, not quarts. I get all the ingredients from agricultural supply stores. If you try to buy things at your local big box Wal-Mart type store, it will be cost prohibitive, at least for me.
