Blood meal is correct at 12. What is wrong is cottonseed meal which is 4-6 instead of 46.

 

[Rajesh Sethi]

Blood meal is correct at 12.

I thought it might contain some P and K, blood meal contains other micronutrients also, don't you think!

Yes, blood meal contains a lot of iron plus a bunch of other trace elements but no P or K

My are banned using fertilizer that contains NP for the next 3 months. My plants will have to suffer for a little while.

And what about vermicompost? What I put for my worms to eat will affect the liquid fertilizer?

Only to the extent that their digestive tract influences their fecal output

Is there a reason why blood meal is listed twice? I feel like I've seen this before, but I'm not sure.

 

[Chuck]

I suppose it means fish blood meal and fish bone meal. Blood Meal is from cattle and hogs.

ooooooh fish blood meal. Thanks Chuck!

The fbb is just a pre-blended popular organic combo product. The blood meal is the stand alone component. From what I gather of the boards, it seems more common in Europe but here in the states we get the separated component on the shelf mostly.
