What are the fertilizer requirements for scallions? Please give an introduction. Scallions are heavy feeders, but their demand for fertilizer is not high. The root system of scallions has weak absorption capacity, so to increase scallion yield, attention must be paid to applying more fertilizer.

According to measurements, for every 1000 kg of fresh scallions grown, about 2.7 kg of nitrogen (N), 0.5 kg of phosphorus (P2O5), and 3.3 kg of potassium (K2O) need to be absorbed from the soil. Scallions absorb the most potassium, followed by nitrogen, and the least phosphorus. In addition, calcium, magnesium, manganese, boron and others also play a certain role in the growth of scallions.
