Improvising fertilizer

I have a soil garden in a town where the nearest hydroponic supply is about 1600 km away... thats maybe 1000 miles or so.

I have a minimal wal-mart and canada's favourite hardware store, Canadian Tire in town. I wish Canada Tire had a hydroponics department but it doesn't and it's gardening department stock is reflective of the foot of snow we already have on the ground.
We are heavy into winter already.

Is anyone improvising a decent veg and a bloom fertilizer out of small town limited resources.

couldn't you just order something offline? it's cheaper than going to the store too. try plantlightinghydroponics.com theyre pretty cheap and reliable.

Id like to know how to make a home made boom booster too.
