Now introduce a simple standardized fertilizer equivalent to other fertilizer calculation methods: standard nitrogen fertilizer (nitrogen 21%), generally refers to iron sulfate; standard phosphate fertilizer (phosphorus 12%), generally refers to superphosphate; standard potassium fertilizer, potassium sulfate Potassium nitrite and potassium oxide are both around 60%. The calculation method is as follows: a certain amount of chemical fertilizer = standardized fertilizer dosage × standardized fertilizer content / a certain fertilizer content. For example: 50 kg of standard nitrogen fertilizer for urea: 50 × 21% / 47% = 23 (kg) that is 50 kg of standard nitrogen fertilizer equivalent to 23 kg of urea; another example: 70 kg of standard phosphate fertilizer to diammonium phosphate: 70 × 12 %/42%=20 (kg). That is, 70 kg of standard phosphate fertilizer is equivalent to 20 kg of diammonium phosphate, and 20 kg of diammonium phosphate is also equivalent to 21 kg of ammonium bicarbonate (algorithm as above). The rest are analogous.
