The commonly used nitrogen fertilizers in rural areas are ammonium sulfate, ammonium nitrate, ammonium bicarbonate, ammonium chloride and urea, with different cost performance. The more cost-effective the nitrogen fertilizer is, the higher the nitrogen fertilizer is.
The nitrogen content of urea is 46.67%, and 1 0,000 yuan can buy nitrogen 1 0,000/1,080 * 46.67% = 0.432.
The nitrogen content of ammonium sulfate is 20.69%, and 1, 000 yuan can buy nitrogen 1, 000/450 * 20.69% = 0.460.
The nitrogen content of ammonium nitrate is 35%, and nitrogen can be bought for 1000 yuan1000/810 * 35% = 0.432.
The nitrogen content of ammonium bicarbonate is 17.28%, and 1000 yuan can buy nitrogen1000/330 *17.28% = 0.524.
