Most protein for the dollar: Poultry feed vs. soybean meal

15 years ago

I'm going to try out organic fertilizer and have been checking the local feed stores and finding out what provides the most protein for the dollar. I heard soybean meal is high in protein and can find that for about $10 per 50# bag. But doesn't SBM have less than 10% protein?

The best I can find for amt of protein per dollar is a 50# bag of Meat Maker Poultry Feed with is $11, but is 21% protein. Would this work out fine as fertilizer?

I plan to rotate other organic fertilizers into the mix, but would just about any high protein animal feed make decent organic fertilizer? Do the soil microbes eat virtually any protein that is added to the lawn?
