What is nitrophoska fertilizer: application of the product

Fertilizer description

Nitrofoska is a complex mineral fertilizer containing nitrogen, potassium and phosphorus. It is produced industrially from apatites or phosphorites, after their interaction with acids and the addition of several more components. It is sold in the form of light-colored granules with a diameter of 5-6 mm. Packaged in 1, 2 or 3 kilograms in polyethylene or triple paper bags, it is well stored in dry, cool and ventilated rooms. It can be used for feeding almost all agricultural and cultivated plants, with laying in the soil during autumn or spring digging or directly during planting, or with additional feeding, in the form of granules or solution.

What is included

The fertilizer contains nitrogen, phosphorus and potassium, usually in equal proportions, and not less than 10-11% of each microelement. Nitrogen is contained in the form of ammonium chloride and ammonium nitrate. Phosphorus - in the form of superphosphate and precipate. Potassium nitrate provides two trace elements - potassium and nitrogen. Ammophos is phosphorus and nitrogen. The fertilizer also contains calcium-containing salts and compounds. If sulfuric acid was used in the production and the finished fertilizer contains sulfur, it is well suited for cucumbers and beans.

Fertilizer with a high content of potassium and sulfates is good for ornamental plants. Nitroammophoska with additional phosphorus compounds is ideal for tomatoes and other nightshade crops. Also on sale there is a nitrophoska with an additional magnesium content. With the usual action of nitrophoska on plants, nitrogen is first absorbed and allows you to build up green mass, then, when fruit setting begins, phosphorus, which gives a good dense tissue structure, and a little later, when the fruits enter the phase of active growth, potassium, which has a positive effect on taste. ...

Instructions for use

Application is possible on all types of soils and under all crops, the exact dosages should be found in the instructions. Digging a vegetable garden in the fall, you can close up 70-90 grams per square meter. If the soil is heavy, then the fertilizer should be filled deeply.

If the soil is sandy or sandy loam, then there is a danger that nitrogen components will quickly be washed out of the soil. Therefore, on such soils, nitrophosphate is applied during spring digging or directly during planting. Top dressing of fruit trees and shrubs should be done in the spring. Apple trees are fed after flowering - 50 grams of fertilizer must be dissolved in 10 liters of water. Under each tree, up to 25-30 liters of solution is applied; for a large tree, the amount of solution can be increased.

If the weather is rainy, then the granules are introduced into the soil by digging. Conversely, before feeding, dry soil should be watered with plain water so as not to burn the roots. If the seedling is planted in good garden soil, then no additional fertilizing is needed before fruiting.Fertilizer for pear trees can be applied in a similar way, although nitroammofosk is more useful for them. For stone fruits, you need to choose nitroammophoska or apply nitrophoska in lower concentrations.

After flowering, no more than 200 grams of nitrophoska is applied under the cherry bush, in the form of granules or solution. For gooseberries or currants - up to 100-150 grams. For raspberries - 60 grams per square meter. You can also feed garden strawberries - add a few granules in the hole when planting, or 30 grams (2 tablespoons) per 10 liters of water - and up to half a liter of this solution for each bush at the end of flowering.

The general application rates of nitrophoska for garden crops are up to 70-80 grams per square meter during spring digging or for each plant according to its own standards when planting (first feeding). Additional top dressing during the season - in the first half of the season, before the start of active fruiting - up to 30-40 grams. They are very fond of nitrophosphate, especially phosphorite, tomatoes. If the quality of the seedlings leaves much to be desired, then the first feeding can be carried out even before planting in open ground, after a pick. To feed the seedlings, take 15 grams of fertilizer and dissolve in a liter of water. This concentrate can be used for 40-50 seedling bushes. When planting seedlings, up to 15 grams of granules can be added to each hole by mixing them with the ground.

Or water the planted seedlings by dissolving 50 grams of nitrophoska in 10 liters of water. It is recommended to repeat this feeding two weeks after planting. Bell peppers are fed with nitroammophos or nitrofos in the first feeding (when planting seedlings or, if the seeds were sown directly into the ground, then at the stage of the third or fourth shoot). Eggplants can be fed with a solution of 20 grams of nitrophoska per 10 liters of water, two weeks after planting the seedlings in the ground.

For potatoes, nitrophoska can be added during autumn digging or directly during planting - 1 spoon of granules per hole, mix well with the ground, make sure that the granules do not come into contact with the planting tubers. For cucumbers, fertilizer is used before sowing in the soil or in the first feeding - at the moment the first ovaries appear, a tablespoon of granules (maximum two) per bucket of water, up to half a liter of solution for each plant. Under zucchini and squash, nitrophoska is applied once or twice a season. The first is before flowering, the second is at the beginning of fruiting. Dissolve 20-30 grams of fertilizer in 1 liter of water, up to one and a half liters of solution for each plant. Pumpkin also loves nitrophosphate. The first feeding with this fertilizer is carried out at the stage of the appearance of true leaves (fourth to fifth leaf) - while adding 10 grams of dry granules to the soil. The second time - at the beginning of the formation of lashes, 15 grams of granules are dissolved in 5-10 liters of water (depending on the weather) and the plant is watered.

Differences between nitrophoska nitroammofoska

These are fertilizers of the same class, based on a mixture of nitrogen, phosphorus and potassium in equal amounts. But the concentration of nutrients in nitroammofosk is from 16% each. Based on this, we can say that nitrophoska and nitroammophoska are interchangeable, but their use must be adjusted for the concentration of nutrients. In addition to the inscription on the package, nitroammophoska can be distinguished by its color - usually these are pink granules. As for the composition, in nitroammofosk nitrogen, phosphorus and potassium are in easily digestible chelated forms, and therefore, when fertilizing the soil, they will be needed less. In any case, the main thing when using fertilizers is moderation. It is better to under-feed the plants a little than to ruin them by “gluttony”.
