Complex fertilizers for plants are used at all stages of their cultivation, and are also applied in the autumn and spring periods for digging. They are considered the most balanced and useful for all horticultural crops. One of these top dressings is nitrofoska. The composition of this fertilizer can be called universal.
Nitrofoska contains nitrogen (16%), phosphorus (16%) and potassium (16%). In addition, it contains various trace elements necessary for plants: manganese, boron, copper, magnesium, molybdenum, zinc and cobalt. This allows you to significantly increase the yield of vegetable, fruit and berry crops.
Nitrofoska, the composition of which is perfectly balanced, among other things, does not contain impurities harmful to humans. For example, nitrates are not present in it. Therefore, using this fertilizer, you can get an excellent crop of vegetables and fruits, environmentally friendly and healthy, and they will have excellent natural taste.
To increase productivity, it is necessary to strictly observe the dosage of fertilizers, including such as nitrofoska. Its use is advisable mainly on acidic and neutral soils. In the event that this top dressing is used to increase the fertility of the soil of the entire garden as a whole, about 90 g is applied per square meter. The nitrophoska is especially effective on sandy, clay and peat-bog soils.
If nitrofoska, the composition of which is designed for top dressing of both fruit and vegetable crops, is applied to any of them specifically, the following dosages are observed:
- cherry - about 200 g;
- adult apple tree - about 450 - 600 g;
- strawberries - 35 - 45 g;
- gooseberries and currants - 120 - 150 g;
- raspberries - 60 - 75 g.
This top dressing is produced in the form of readily soluble granules. Therefore, nitrofoska, the composition of which is strictly balanced, is easy to use. Due to the fact that manufacturers prudently process granules with various condensing additives, the fertilizer does not coalesce, since individual particles do not stick together. This dressing can be stored for a long enough time.
Often, to increase the fertility of the soil in the area, it is not nitrofosk that is used, but nitroammophosk - a fertilizer whose application is identical. She is somewhat more nutritious. Its indicators in this regard exceed the nitrofoska indicators by about 11%. Therefore, when applying nitroammophoski to the soil, all of the above figures need to be reduced by one and a half times. Most often it is used before sowing
vegetable crops. Further, it is added to the soil directly during planting. This fertilizer is produced in the form of pink granules. Both of these top dressings are stored in closed rooms in order to prevent soaking under the influence of rain or groundwater.
It is best to use these complex fertilizers in dissolved form. For example, after flowering of fruit and berry crops is completed, they are fertilized with 2 t / l nitrophoski or 1.5 t / l nitroammophoski dissolved in a ten-liter bucket. This dose is designed for one bush of any berry culture and for 5-6 rows of strawberries.
