Fertiliser having high nitrogen content is :
(1) Urea
(2) Ammonium sulfate
(3) Ammonium nitrate
(4) Calcium citrate
Answer: (3) A growth fertilizer will have a high N content and relatively low P and K content. Ammonium nitrate is the highest Nitrogen fertilizer you can buy, and it is potent stuff. It is usually rated as 33-0-0 or 34-0-0. The bag contains 33% or 34% Nitrogen, and the other 66% or 67% is an inert material. Other formulations of growth fertilizers will contain 5, 6, or even seven times more Nitrogen than anything else.
