Fertilizer Ammofosk – application features for growing potatoes

We always plant large quantities of potatoes on the site, but there is not always enough organic matter to fertilize all plantings. After small calculations, I concluded that it is more economical to use mineral fertilizers. A neighbor has long recommended trying Ammofoska. Tell me how to use Ammofoska correctly and in what quantity for fertilizing potatoes?

ammophoska Among the complex mineral fertilizers, ammofoska is very popular among gardeners. This is due to the fact that it contains many nutrients necessary for the development of crops. A small amount of the drug can be used to fertilize the entire garden, while the plants will receive a full range of trace elements, which is very beneficial from the financial point of view. That is why ammophoska is often used to fertilize potatoes, which occupy most of the garden..

Composition of the preparation


The main constituent elements of ammophos are:

  • potassium (15%);
  • phosphorus (15%);
  • sulfur (14%);
  • nitrogen (12%).

All four trace elements play an important role in the growth and formation of root crops and are the key to a plentiful and high-quality potato harvest..
