Soybean Meal vs Alfalfa Pellets?
New to owning and caring for a lawn and looking to go organic this year.
After conversing at length with dchall, and seeing some great pictures posted, I'm sold on organic fertilizers. As I began calling around for local prices, I found SBM for $18/50# and alfalfa pellets for $21/50#. Fairly close and I haven't shopped around yet.
From what I understand, key difference is protein/nitrogen content. SBM is somewhere around 40% protein/6% nitrogen and alfalfa is more like 14-17% protein/3% nitrogen.
I know nitrogen promotes leaf growth. But that's where it ends for me. Is more nitrogen better, or is more nitrogen better only at certain times of year? Does SBM or alfalfa have any other pros/cons beyond just the protein and added OM value?
I thought I read something about alfalfa having a growth hormone effect?
Your assistance in furthering my education is appreciated.
