How do various organic sources rank in terms of speed of release?

Post by Green »

Things like biosolids, Protein Hydrolysate, feather meal, chicken manure, grains, etc...

Which are the slowest N sources, and how do they all rank on that scale in terms of how long they last?

Nice link.

Now, anyone know where biosolids and Protein hydrolysates fit in?

I guess I should have used the word breakdown or availability rather than release.

I'm racking my brain to recall if I ever saw biosolids listed with "organics" in a chart. Quite possibly, I have. However, most sources nowadays poo poo biosolids as not being "organic", even though they are definitely a carbon based renewable, and a great source of organic nitrogen. In fact, Milorganite removed the "organic nitrogen" verbiage from their labeling (I believe they were forced to do so). OMRI and the gov't no longer consider biosolids as "organic", and cannot be used to grow crops labeled as "organic". What a joke! A rose is still a rose, even by another name.

Sorry for the rant, but it is the truth as far as I know. If I come across a chart with biosolids and/or protein hydrolosate, I'll link to it.
