It is difficult to imagine a good harvest of cucumbers without fertile soil.
Therefore, the gardener’s task is to ensure that the area allocated for growing cucumbers becomes fertile.
What needs to be done? Dig the area to a depth of 40 cm and fill it with organic matter - straw or last year's grass.
To speed up decomposition, you can add a small amount of ammonium nitrate.
Now cover the organic matter with soil, then thoroughly moisten the area. After about 2 weeks, the soil will settle and compact - now it is saturated with all the necessary nutrients, suitable for planting cucumbers.
When planting seedlings in open ground, fill the bottom of the hole with any potassium fertilizer - for example, potassium sulfate.
Alternatively, use a fertilizer that contains nitrogen (nitrogen phosphate or urea).
Of course, you can not bother and not put anything in the hole - in the event that you are the happy owner of fertile soil. However, experienced gardeners advise not to neglect this trick in order to achieve maximum benefit from mineral fertilizers with their minimum costs.
