The process of tuber formation of potatoes is accompanied by intensive absorption of "sprouts" of nutrients from the soil. But even chernozem is not able to fully provide the culture with all the chemical elements necessary for it to develop actively. To achieve high yields of its sotkas, it is necessary not only to properly cultivate plots, but also to actively use fertilizers.
What kind of "feeding" is best suited for potatoes, the features of the application of its various types and will be the subject of conversation.
Next - only a general overview of some types of fertilizers for potatoes. A single recommendation for all climatic zones, various soils and so on simply does not exist. On what all the same to stop?
- Try those fertilizers that are listed below. If the crop area is significant, then it is advisable to divide it into parts and use one of each segment. By results of the first couple of years it will be possible to come to a conclusion, what exactly is the most effective top dressing in local conditions.
- Ask the experienced truck farmers in their region how they solve the problem of fertilizing potatoes.
- The general opinion of those who independently cultivated this culture, the best solution is a complex method of fertilization. This means that it is necessary to use both organic and mineral compounds for top dressing.
Types of fertilizers for potatoes
Organic
It is believed that the introduction of such fertilizers allows you to water the plots less often. If they are far beyond the city, and even on wastelands, the problem of water delivery is quite acute. Many truck farmers do not do this at all, completely relying on natural irrigation - rain.
Dung

The question of the expediency of using manure causes a lot of controversy. This technology has both explicit adherents and irreconcilable opponents. Summarize all the opinions.
"For"
- Availability.
- This fertilizer will be free;owners of living creatures in the private sector will also be grateful for their help in recycling.
- The introduction of manure increases yield almost doubled. It promotes the retention of moisture in the soil, makes it soft, enriches with oxygen.
"Against"
- Probability of entering into the soil of the larvae of the May beetle along with the manure.
- The risk of the appearance of potato, scab, on the tubers.
Ash
This representative of the group of organic fertilizers has no opponents. The only thing that requires clarification - the ash is not used, but wood. Its additional attractiveness is that, in addition to the function of feeding with useful substances, it provides reliable protection of tubers from various biological pests.
Ciderates
This is how some representatives of the flora are called - peas, sweet clover, lupins and the like. Vegetable mass simply wrapped in a cultivator or a tractor in the ground.
Application of organic
It has been introduced into the soil since the fall, before preparing the site for winter. Organic fertilizers are scattered on top, about the amount of buckets per hundred square meters.

In principle, the technology is simple and straightforward.
In addition to manure, effective organic fertilizers are bird droppings, humus, peat. The method of introduction into the soil is identical.
Feature of organic

- Potassium sulphate - 2.
- Superphosphate - 1.

Application - spring soil fertilization.

To go through the whole assortment is pointless, without knowing all the features of the climate and the specific site. But the most interesting compositions from the point of view of increasing crop yields should be stopped.
Precise advice on the use of a particular product is provided on its packaging or insert.

Here are the fertilizers of this group and should be selected first.
- When applying fertilizers, you must follow the measure. Their excess can have the opposite effect - reduce the yield of potatoes.
- This does not apply directly to the topic of fertilizers, but it improves yields. Before planting potatoes( which is not known to everyone, but who are aware of it, they are often ignored), it is processed by prepared( or purchased) solutions. They must contain elements such as copper, manganese, boric acid. This stimulates the production of vitamin C. in the tubers.
