The output of peanuts without fertilization is called the yield of empty fields. The nutrients they absorb come from the soil and nitrogen fixation of rhizobia. Based on the principle that the output of peanuts is derived from soil production and increased yield from fertilizers, subtracting the yield of empty fields from the target yield is the increase in yield from fertilization. Fertilizer requirements can be calculated according to the following formula.

Fertilizer requirement amount = crop unit yield nutrient absorption amount (target output - blank field yield)
Fertilizer nutrient content (%) fertilizer utilization in the season (%)
For example, for a farmer's peanut field, the output of each 667m 2 blank field is 150kg and the target output is 300kg. The amount of urea should be applied every 667m2:
Urea consumption = 0.068 (300-150)/0.460.50 = 44.35 (kg)
If 60% of nitrogen comes from rhizobia, the actual amount of urea should be 17.74 kg per 667 m2.
Per 667 m2 should be applied to the amount of calcium phosphate:
The amount of superphosphate = 0.01 (300-150)/0.180.20 = 41.7 (kg)
The law applies to areas where there is no test method. The disadvantage is that the yield of empty fields is affected by many factors, and it is impossible to express the abundance of certain elements in various elements.
