Fertilizing the garden on a budget

In addition to kitchen compost, how are permies fertilizing the garden?
I was very inspired by this article, Why Vermont farmers are using urine on their crops
Any suggestions on avoiding the high prices for organic fertilizers?

What a great question!

Compost tea is my favorite suggestion though weed tea works.

Chop and drop method of getting rid of weeds works, too.

In a word - mulch!

I'm still working it out, but a chop and crop in situ of green weeds and comfrey leaves is my plan. I use urine on the comfrey rather than direct on the vegetables but really it doesn't matter.

Thanks for the great ideas Anne and Nancy. With ideas like these, gardening doesn't have to be so expensive!
Here is another frugal fertilizer story from my garden that makes me happy.
Over the years, my fruit trees have become more prolific. Pruning, watering, and fertilizing takes time but not money, thanks to a friend who came up with a brilliant exchange. As background, my friend lives in a condo where the landscape is planned and maintained for the residents. There are no fruit trees. My friend really enjoys the fruit that I grow and she is committed to reciprocating for the harvest. Like me, she is pretty thrifty.
So she came up with a strategy that really works. Every other day she drives to the local coffee shop, picks up three 5 gallon buckets of coffee grounds and drops off 3 empty buckets for the shop to fill over the next couple of days. The coffee shop is really pleased to get rid of the grounds to help gardeners.
A few times a week, my friend stops by and scatters spent coffee grounds along the drip line of my fruit trees.
We are both so pleased with this casual arrangement! The fruit trees thrive with layers of coffee grounds around the fruit tree drip lines (covering the mulch as Nancy describes above). My friend receives boxes of cherries, plums, apples and pears at peak flavor. What could be better than free fertilizer for me and free fruit for my friend?

We are using our home compost as well as the hot compost of our local solid waste facility. Compost tea (lazy bokashi) and diluted urine too!
