In autumn during soil preparation, you can make ammonium nitrogen fertilizer (ammonium sulphate, ammophos, urea, etc.).

Nitrate nitrogen moves with water, so mineral water of the group of nitrate, add in advance is not necessary, all of the nitrogen will be washed out.

It also takes into account the type of soil. Ammonium fertilizer acidified the soil, they are better suited to alkaline and slightly acid, and nitrate to take, they should be used on acid soils.

Potassium on heavy soils is fixed, and the lung is washed out. Therefore, in the first case make in autumn to a depth of 20-25cm, and the second in the spring.
