Nitroammophoska

Thanks to nitroammophoska, plants get a good start in spring due to nitrogen (N), which is responsible for the growth of stems and leaves, phosphorus (P), which becomes available gradually and stimulates the development of the root system, and potassium (K) – which is responsible for the formation of flowers and fruits .

The minimum chlorine content and the classic NPK formula make nitroammophoska a universal fertilizer for almost all types of soil. However, it is not recommended to use fertilizer for more than 2 seasons in a row – it should be alternated with the introduction of organic matter.

What is nitroammophoska

Nitroammophoska is a complex complex mineral fertilizer intended for pre-sowing and sowing application. In the first case, the fertilizer is applied under incorporation over the entire area of ​​the site. In the second – into the grooves between the rows to a depth of 6 – 8 cm. 

The value of this fertilizer is that when it enters the soil, phosphorus becomes readily available to plants. 

Nitroammophosic composition

The classic composition of nitroammophoska is nitrogen (N), phosphorus (P) and potassium (K) in a ratio of 16:16:16 or 17:17:17. The first brand contains potassium sulfate, the second – potassium chloride.

The chemical formula of the fertilizer is NH₄H₂PO₄ + NH₄DO NOT₃ + KCL (1).

Properties of nitroammophoska

Nitroammophoska is a granular loose powder of milky pink color. The fertilizer does not produce dust, has good flowability, is not washed out of the soil, and has the ability to release nutrients gradually. 

However, like all nitrogen-containing fertilizers, it tends to quickly lose nitrogen, therefore, nitroammophos is applied for embedding into the soil to a depth of at least 6 cm. It is also effective to apply fertilizer in liquid form into irrigation grooves, followed by mulching.

Apply fertilizer on moist soil or with subsequent watering. In the south, especially on alkaline soils, nitroammophoska is used subject to regular irrigation.

When using nitroammophoska, application rates are strictly observed, since excessive doses can lead to the accumulation of nitrates in fruits, especially in green crops.

The use of nitroammophoska in the garden and vegetable garden

Nitroammophoska is recommended for use on any type of soil, in open and closed ground, for almost all cultivated plants: fruit and ornamental trees and shrubs, vegetables, flowers, lawn grasses (2).

making Dates 

Nitroammophoska brings the greatest efficiency when applied in the spring, as soon as the soil warms up, and in liquid dressings in the first half of summer.

For use in the fall, choose brands of nitroammophoska with a low nitrogen content. In general, autumn fertilization is not rational.

Dosage of application

Doses of introduction depend on time and culture.

• for continuous application in spring – 40 – 50 g (3 tablespoons) per 1 sq. m;
• for spring feeding of perennials and lawn grasses – 40 g (8 teaspoons) per 1 sq. m;
• for spring feeding of trees and shrubs – 30 – 40 g (6 – 8 teaspoons) per 1 sq. m near the trunk circle;
• in planting holes when planting seedlings of eggplant, peppers, tomatoes, cucumbers, zucchini and pumpkins – 2,5 g (0,5 teaspoon) per 1 hole;
• in the planting hole when planting potatoes – 5 g (1 teaspoon) per 1 hole;
• for feeding vegetable and flower crops, roses and indoor plants in May-July – 20-30 g (4-6 teaspoons) per 10 liters of water.

Application methods

Gardeners and gardeners use 2 ways to apply nitroammophoska.

• application of dry fertilizer – for digging or in grooves with obligatory soil or mulch: it is better to do this as soon as the soil warms up, but it should still be wet, or in dry weather, providing watering;
• watering with fertilizer solution – in May-July (up to 2 dressings) under the root: 20 – 30 g (4 – 6 teaspoons) fertilizers are dissolved in 2 – 3 liters of warm water (18 – 22 ° C), stirred well until completely dissolved, then the volume is adjusted up to 10 l and is used for irrigation under the root on moist soil (3).
