Are they assuming cow and steer or grass fed or grain fed with this numbers?!thistlebloom said:Interesting chart of the NPKs of different manures. Rabbit came out as twice as much nitrogen than even chicken manure- go buns!
It is curious to me that cow and steer had different ratings.......?
I suppose that what they are eating would make a difference in the NPK, maybe cows get less protein than steers?
