Help me find the right fertiliser?

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.

Plant growth is about much more than N P & K. - unless you're advertising NPK fertilisers! You could keep your cash in your pocket, be self sufficient, and make your own (free) natural fertilisers?

There are loads of resources out there - here are some I've used
18 day fast composting
Info about NPK content of organic fertilisers
Explore David the Good's compost resources
8 best natural fertilisers according to the Farmers Almanac
Here in France locals make and use Purine d'ortis - Nettle tea. Pull up nettles, soak in water till it's rotted and stinks - dilute and water plants.
Same with Comfrey leaves
Same with weeds you're pulling up
If you're eating fresh food, you're creating waste from peelings etc - make compost tea with those, dilute and water your plants.

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

Add:
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.

Trace, how much does that run you?  It makes a little over 5 quarts, right?  How many square feet does that cover?

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.
