Nitrogen is the basic resource for the normal functioning of both plant representatives and various living organisms. It is part of the so-called "life-four", which also includes oxygen, hydrogen and carbon. These elements constitute the most important part of the tissue composition of most living micro and macroorganisms and they are contained in special nitrogen fertilizers.

- On the negative effect of overdraftharvest using only natural resources of the soil is almost impossible. Therefore, needs to replenish the stock of nutrients. What will these substances be - the garden owners think over in their own way, and the choice is influenced by the types of crops, the time of year, and the experience of previous feedings.
The nitrogenous component is, for example, chlorophyll, which is important for the absorption of solar energy, alkaloids, lipids and many more other compositions that are vital for vegetation.Fertilizers based on this element are valuable when applied to the soil at the right time.
In the springtime, gives the saturation of young stems in the active growth stage, gradually moving to new buds, leaves and stems.
After pollination of plants, nitrogenous substances reach the reproductive organs, where they settle in the protein form. Protein acquires greater value in fruits, is observed as a more active growth of , the quantitative and qualitative component of the harvest is increasing.
How to understand that the plant lacks nitrogen fertilizers
A clear sign of nitrogen deficiency is the color of the foliage - jaundice , and a pale yellow version is possible. The process of yellowing is initiated from the edge of the leaves and spreads to the center. The lamina becomes thinner and softer.
The first leaves to turn yellow. In extreme cases, the foliage can dry out completely and fall off: all the nutrients are used to maintain the upper shoots or fruit.
There are two reasons for the lack of nitrogen in this case:
- The plant did not receive proper feeding;
- Soil strongly acidified , which complicates the absorption of nitrogen.
. However, the soil needs to be updated or replaced, and the time and rules for feeding are observed.
About the classification of
fillers The described fertilizers are obtained from ammonia synthetic properties and are divided into several types characterized by their features:
- Ammonia , with the described substance in the form of ammonia in combination with mineral acid. These include ammonium chloride, bicarbonate and ammonium sulfate, ammonium fertilizers of liquid type.
- Nitrate , which have salts of nitric acid. Sodium nitrate, potassium nitrate, calcium nitrate are considered to be this variant.
- Amide containing the substance in amide form. This type implies urea, calcium cyanide, urea formaldehyde fertilizers.
There are types of fertilizers where the nitrogen component comes in several forms. This is an ammonium nitrate species, with calcium-ammonium and ammonium nitrate. The latter can act both in ammonium and in nitrate form.
Classification and combination of additives with nitrogen are associated with soil type, climatic characteristics and differences in the care of that or another plant.
How much correct to make the application of fertilizer
It is important to understand that all specified values are very approximate.
- On average, ranks from 600 to 900 g as a base for fertilizing potatoes, vegetables, fruit and berries and flower crops.nitrogen per 100 square meters.meters
- If we are talking about top dressing, then for vegetable crops and potatoes make approximately 200 grams of per 100 square meters, and for berry and fruit varieties - 200-300 grams of .
- For a suitable liquid consistency, the calculation is from 15 to 30 g .on 10 l.water.
- When planning the use of a substance outside the root, you need 25-50 g .on 10 liters. Fertilizer is distributed on 100-200 m2.
For a larger guideline, we present a table with nitrogen content for any of the fillers with their name.
Fertilizer, 4% Calcium nitrate 13,5-15,5% organic and nitrate Ammonium nitrate 34-35% Calcium-ammonium nitrate 20.5% ary ammonium nitrate 20.5% Ace ammonium nitrate 20.5% Ace ammonium nitrate 20.5% Ace Ammonium Nitrate 20.5% Ammonium Nitrate0% Ammonia based on calcium nitrate 30.5-31.6% Ammonium sulfonitrate 25,5-26,5% Amide Calcium Cyanamide 18-21% Urea 42,0-46,2% Urea-formaldehyde and urea-methylene( slow acting) 38-42% on ammineurea-based 37-40%
For which crops it is advisable to use nitrogen
In essence, this component is important for any plant, including when grown at home, the only difference is its quantity. In this regard, crops are divided into:
- Plants that fertilize in the spring before planting in the ground. Calculation of ammonium nitrate - 25-30 g .on 1 square meter of the area of crops. These include potatoes, eggplant, pumpkin, cabbage like vegetables;Cherries, raspberries, plums, blackberries like fruit and berry crops, roses, peonies, phloxes, carnations, zinnias and others as floral options.
- Cultures that need less nitrogen fertilization - 20 g .per square meter. These are vegetables such as tomatoes, cucumbers, corn, beets, garlic;fruit varieties - apples, gooseberries, currants, all annual flowers and delphinium.
- The third group requires moderate element filling. This includes radishes, onions, early potatoes, pears, primroses, daisies.
- Plants that need minimal nitrogen — like aromatic cultures, peas and beans, as well as flowers such as heather, purslane, Japanese azalea, rhododendron.
On the negative effect of an oversupply of nitrogenous supplements
Both the lack of nitrogen and the excessive introduction of a substance have a negative effect. From this excess begins too active development of the aboveground mass of cultures. The leaves expand, become larger internodes.
The leaves are pompous and soft, and the flowering is fast and scanty, sometimes even absent. Therefore, the ovary is formed poorly, affecting the absence of future fruits and berries.With an overabundance of substance on the leaves, peculiar burns can be seen, and then the leaves quickly fall off, which can lead to partial loss of the root system.
All crops need nitrogen. It is important to determine its dosage and make all the rules, including the characteristics of each plant.
