Usually, mineral supplements are chosen, the components of which are most useful and at the same time are 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.
This fertilizer is used 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:
- sulfuric acid - sulfur, introduced together with nitrogen, participates in the synthesis of plant proteins and promotes better absorption of nitrogen. Additionally, it repels some pests (mites). Great for feeding cucumbers, tomato, cabbage and beans. It manifests itself best on sod-podzolic soils;
- sulfate is characterized by a high potassium content. It is most effective when used for growing flowers. Since potassium is an important element for the full formation of flower buds and determines the size of flowers, their number and color saturation. It is recommended to use sulfate nitrophosphate when breeding deciduous ornamental plants;
- phosphorite nitrophoska is valued as a top dressing for tomatoes, as it promotes the formation of ovaries.
It is allowed to use nitrophoska as the main fertilizer for sowing, transplanting and during the growing season of plants. Fertilizing in the form of granules or solution:
- when using dry 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).
Not to be confused with nitrophosphate azopho (nitroammophos). These are substances that have approximately the same set of elements. However, the application rates do not coincide. Because there is more phosphorus and nitrogen in azophos (moreover, phosphorus is contained in a completely water-soluble form).
Use at their summer cottage
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 culture. It is recommended to add fertilizer to the soil in the spring, directly when digging a 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). Fodder is applied with deep digging of the earth at the rate of 75-80 g per square meter of area.
For potatoes
Nitrophoska is important for a high yield. Choosing a composition must be chlorine-free. Lay the granules when planting tubers (put 1 tbsp. L of the mixture in each hole and mix well with the ground). On large areas, it makes sense to scatter fertilizer when digging the entire site (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 acid 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, when growing seedlings, the soil was not fed, then nitrophoska is applied when planting seedlings.A teaspoon of granules is poured into the hole and mixed 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 no fertilizer was 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 in 10 liters of water is already diluted 30 g of the mixture.
Fertilizing the soil for cucumbers
Nitrophoska increases the yield of vegetables by about 20%, and all three components are actively working: 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 are poured at the rate of 30 g / sq. m. During 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
For this culture, phosphorite nitrophoska is best suited. When planting seedlings on the site, 1 tbsp is poured into the holes. l of granules and mix well with the soil. Or the transplanted seedlings are watered with a solution (50 g of granules are diluted in 10 liters of water). After half a month, re-feeding of tomatoes is carried out.
Various vegetable crops
It is also very common to use nitrophoska for feeding other crops. Individual norms for vegetables are recommended:
- zucchini are fertilized twice. The first time feeding 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 nitrophosphate is diluted in 10 liters of water. Fertilizers are re-applied during the formation of lashes;
- Bulgarian pepper is fertilized when planting seedlings on a site or when 4-5 leaves appear (if seeds were planted in the ground). Dissolve 50 g of granules in 10 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 nitrophosphate.
Or you can simply add 70-80 g of granules per square meter when digging.
Fruit trees and shrubs
In areas with sandy and sandy loam soils, the likelihood of rapid leaching of nitrogen increases, therefore, nitrophosphate is sprinkled in the spring when digging or directly when planting plants:
- when fertilizing fruit trees, the dry mixture is poured into a hole around the trunk (on highly moistened soil). For pome trees, take 40-50 g of granules per square meter of area. Pour 20-30 g per square meter under stone fruit trees;
- dry granules are usually also poured under the bushes and the earth is dug shallowly. For gooseberries, currants, 140-155 g per square meter are enough. 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 room. Since the mixture is considered flammable and explosive, it must not be stacked near a fire.
Security measures
Nitrophoska is harmless to skin, does not affect 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 your eyes, it is recommended to rinse them thoroughly with clean water. If the solution accidentally gets into the stomach, it is advisable to rinse.
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 harmonious development of seedlings and intensive fruiting of crops.
