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.
