amending new veggie garden’s soil
I took a home soil test and my soil has a pH of 5, so it's pretty acidic. The potassium level is on the high end, but the nitrogen is extremely low and the phosphorous level is low. What should I add to it this fall so that it will be ready for planting in the spring? I live in Massachusetts. I have just rototilled the plot. It is 300 sf. It is also brand new. I would like to use organic amendments. I saw wood ash is good for bringing the pH up - and I have three fireplaces so I have a source! But I also read that it brings up the potassium level which is also really high. So maybe that's a bad idea. What do you suggest I do? I am not far from a beach - would seaweed help somehow? I added a little chicken poop I bought in a bag.

The two most common types of lime are allowed in organic farming/gardening, but slaked lime and burnt lime are not considered organic:
Seaweed does help with soil fertility and is great for plants:
