One of the important conditions for obtaining a good potato harvest is the introduction of certain nutrients into the soil.
Moreover, the use of certain fertilizers must be timely.
In other words, a gardener should not only familiarize himself with the list of fertilizers needed for garden crops, but also learn about the most optimal time to replenish the deficiency of compounds in the soil.
There are four essential fertilizers for potatoes: without them, the growth of tubers will not be complete.
Mandatory fertilizers for potatoes
To ensure that the yield of garden crops is high, the following agents should be added:
- ash;
- ammonium nitrate;
- potassium sulfate;
- superphosphate.
As you can see, potatoes need both mineral fertilizers of all main types (potassium, phosphorus, nitrogen), and “organic” fertilizers.
When to apply fertilizer
Ammonium nitrate should be used at the first stage of plant development. And in the period when the stems are thin and the leaf blades are yellowish.
To create the product, add 20 grams of fertilizer to a bucket of water.
During budding, the garden crop needs unburned wood residues and potassium sulfate. In both cases, 20 grams of the product will be needed per 10 liters of clean liquid.
The final stage (when tubers have already begun to form) should be accompanied by the addition of superphosphate.
