Among the popular mineral preparations emit: ammonium nitrate, superphosphate, urea, potassium sulfate, sodium, calcium and potassium nitrate, ammophos, nitroammophoska, potassium chloride, ammonium sulfate, etc. Some mineral fertilizer solutions can be studied below.

  1. 2 weeks after germination, it is recommended to apply nitrogen fertilizers. 15 g of ammonium nitrate interfere with 20 g of superphosphate and pour into 5 liters of water. You can optionally add 10 g of potassium chloride.

  2. 14 days after the first feeding, potassium phosphate preparations are applied. 25 g of superphosphate and potassium sulfate is poured into 10 liters of distilled, warm water and mixed well. The resulting solution can be watered culture. If the growth of greenery stopped at this time, you can make ammonium nitrate in a small concentration.

  3. For the second feeding of onions, it is also recommended to use a solution from a tablespoon of nitrophoska, diluted in 5 liters of warm water.

Important! Many mineral fertilizers acidify the soil, therefore with regular use of them it is necessary to lower the acidity of the earth from time to time.
