Hello Everyone,

I Need to increase NPK of my Natural fertilizer which is from crab shell,it contains Nitrogen : 2.6%,  Phosphorus :  1.2% and   Potassium : 0.5.

But i Need to increase in the ratio of NPK        N= 4  P=3  k= 0.5.

Is  there any natural ingredient of marine waste or any other natural waste  to   increase Nitrogen and Phosphorus?; 

please suggest  me.

Thank you.
