I live in the desert with red clay soil known for being horrible. I have a vegetable garden and over the last year I have worked in amendment and garden mix that has helped with the soil structure making it looser and better draining. However, I tested my soil the other day and it is still completely void of N and K with P only fairing slightly better. Someone at the local nursery recommended working in a broad fertilizer that is 16-16-16 (half fast-acting, half slow-acting, at least the N). However, I was leaning towards a similar product that is 7-7-7 instead (the 16-16-16 fertilizer bag has way too much for my needs).
I am also planning on adding Mycorrhizae, Azomite, and an organic starter fertilizer (slow-acting 4-8-4) to each transplant hole.
My question is, do you think the addition of the recommended amount of the 7-7-7 fertilizer (along with what will be added to transplant holes) is enough to help get the nutrients where it need to be to start off the season or do you have other recommendations for me. Also, I should mention, I am planning on transplanting seedlings and direct sowing seeds within the next 5 days. Thanks for any advice you can offer!
