Usually, mineral additives are chosen, the components of which are most useful and at the same time easily absorbed by plants. Nitrophoska is a complex fertilizer, the main elements are nitrogen, phosphorus, potassium. The drug is produced in white or blue granules, which do not cake during storage, quickly dissolve in water.
Apply this fertilizer on soils with any composition, but it is preferable to use it on neutral or acidic soils.
Fertilizers
Since granules are produced using different technologies, the end results are slightly different compositions:
- sulfate – sulfur, introduced together with nitrogen, is involved in the synthesis of vegetable proteins and promotes better absorption of nitrogen. Additionally repels some pests (mites). Great for feeding cucumbers, tomatoes, cabbage and beans. Best manifested on sod-podzolic soils;
- sulfate is characterized by a high content of potassium. Best used when growing flowers. Since potassium is an important element for the full formation of flower buds and determines the size of the flowers, their number and color saturation. It is recommended to use sulfate nitrophoska when breeding deciduous ornamental plants;
- Phosphorite nitrophoska is valued as a top dressing of tomatoes, as it promotes the formation of ovaries.
It is allowed to use nitrophoska as the main fertilizer during sowing, transplanting and during the vegetation of plants. Feed in the form of granules or solution:
- when using dry top dressing, a mixture with an equal amount of all components is used (16:16:16);
- if you plan to use a solution, then choose a composition with the presence of magnesium (15:10:15:2).
Do not confuse nitrophoska with azofoska (nitroammofoska). These are substances that have approximately the same set of elements. However, the application rates do not match. Because there is more phosphorus and nitrogen in azophoska (moreover, phosphorus is contained in a completely water-soluble form).
Use in the suburban area
Since the production conditions and composition are indicated on the packaging, it will not be difficult to choose a top dressing taking into account the needs of a particular plant crop. It is recommended to add fertilizer to the soil in the spring, directly when digging the site or when forming holes, because nitrogen is easily washed out. Sometimes the mixture is added to the ground in the fall – in the case of heavy dense soils (clay, peat). Top dressing is applied during deep digging of the earth at the rate of 75-80 g per square meter.
For potatoes
Nitrophoska is important for getting a high yield. It is necessary to choose a composition that is chlorine-free. Granules are laid when planting tubers (1 tablespoon of the mixture is placed in each well and mixed well with the ground). On large areas, it makes sense to scatter fertilizer when digging the entire area (in spring or autumn) at the rate of 80 g / sq. m.
Top dressing of cabbage
To obtain a crop rich in vitamins, salts, proteins, sulfuric nitrophoska is used. A week and a half after picking cabbage, fertilizer is used in the form of a solution (10 g per liter of water).
If the soil was not fed during the cultivation of seedlings, then nitrophoska is applied when planting seedlings. Pour a teaspoon of granules into the hole and mix well with the ground. An excellent feeding option is a mixture of 1 kg of vegetable compost, 1 tsp of wood ash, 1 tsp of nitrophoska.
If fertilizer was not applied when planting cabbage, then after two weeks you can water the plants with a nutrient solution (for 10 liters of water – 60 g of nitrophoska). Some gardeners add 200 g to the solution wood ash for the prevention of plant diseases. Re-fertilize the soil after two weeks. Only 10 g of the mixture is already diluted in 30 liters of water.
Soil fertilizer for cucumbers
Nitrophoska increases the yield of vegetables by about 20%, and all three components actively work: nitrogen increases the germination of seeds and promotes the active growth of shoots and leaves, potassium improves the taste of fruits, and phosphorus increases the density and juiciness of cucumbers.
When digging a site in the spring, the granules fall asleep at the rate of 30 g / sq. m. With subsequent watering of cucumbers, a fertilizer solution is added (40 g per 10 l of water). About 500 ml of solution is poured under the root of each cucumber.
Top dressing of tomatoes
Phosphorite nitrophoska is best suited for this crop. When planting seedlings on the site, 1 tbsp is poured into the holes. l granules and mix well with the soil. Or transplanted seedlings are watered with a solution (10 g of granules are diluted in 50 liters of water). After half a month, repeated top dressing of tomatoes is carried out.
Various vegetable crops
It is also very common to use nitrophoska for feeding other crops. Recommended individual norms for vegetables:
- zucchini is fertilized twice. The first time top dressing is applied before flowering, and the second time – before fruiting. In 10 liters of water, 200-300 g of nitrophoska are diluted. About 1-1,5 liters are poured under the plant;
- it is recommended to fertilize the pumpkin when 4-5 leaves appear. In dry weather, 15 g of nitrophoska is diluted in 10 liters of water. Re-fertilizers are applied during the formation of lashes;
- Bulgarian pepper is fertilized when planting seedlings on the site or when 4-5 leaves appear (if seeds were planted in the ground). 10 g of granules are dissolved in 50 liters of water;
- it is recommended to fertilize eggplants half a month after transplanting seedlings to the site. For 10 liters of water, take 20 g of nitrophoska.
Or you can just add 70-80 g of granules per square meter when digging.
Fruit trees and shrubs
In areas with sandy and sandy loamy soils, the likelihood of rapid nitrogen leaching increases, so nitrophoska is scattered in the spring when digging or directly when planting:
- when fertilizing fruit trees, the dry mixture is poured into the hole around the trunk (on highly moist soil). For pome trees, take 40-50 g of granules per square meter of area. Under stone fruit trees pour out 20-30 g per square meter;
- under the bushes, dry granules are also usually poured out and the earth is dug up shallowly. For gooseberries, currants, 140-155 g per square meter is enough. You can pour 60 g under raspberries.
When nitrophoska is applied in granules, they are evenly distributed over the soil surface. After digging the soil, it is recommended to water the earth abundantly.
Fertilizer storage
The granules are packaged in paper / plastic bags weighing 1, 2, 3 kg. Store the fertilizer in a dark, dry place. Since the mixture is considered flammable and explosive, it should not be stacked near a fire.
Safety Precautions
Nitrophoska is harmless to the skin, does not affect the mucous membranes. However, as when working with any mineral fertilizers, it is better to use special protective equipment (rubber gloves).
If the solution gets into the eyes, it is recommended to rinse them thoroughly with clean water. In case of accidental ingestion of the solution into the stomach, it is advisable to do a lavage.
Due to the presence of various nutrients, nitrophoska is widely used. Since the elements of the mixture dissolve well and are evenly distributed, the fertilizer contributes to the friendly development of seedlings and intensive fruiting of crops.
