Strawberry bushes in the spring need recuperation spent on confrontation harsh conditions of winter. A major role in strengthening the capacity of bio-productivity plants plays nitrogen. Spring delicacy for a strawberry among its useful components should be sure to include this element that determines the profusion and quality of the future harvest.

The purpose of introducing nitrogen-containing dressings
Nitrogen - a stimulant of growth of plant organisms. Deficiency of this element leads to the following negative consequences:
- slowing the growth of plants,
- replacing the rich green color of leaf plates to paler shades;
- stop development,
- reduce the number of stems, directly determines the amount of the crop.
However, an excessive content of nitrogen in the basal layer of soil strawberry plantation also adversely affects the culture which grows:
- berries are saturated with excessive nitrates;
- reduced the duration of storage of a ripe harvest;
- the formation of abundant green mass of the plants prevents the development of a sufficient number of stems.
In addition to the application rate of nitrogen fertilizer, you must abide by the rules of dressing. As a preparatory phase activities must be carried out purification beds from last year foliage, under cover which usually winter eggs or larvae of pests and pathogens. After removal of potentially hazardous residues is necessary to loosen the soil.
Application of nitrogen fertilizer on land occupied by planting strawberries, must be as careful - you need a nutrient solution pour the basal portion of the soil under the bushes of plants in contact with the active mixture on the surface of the leaves, they should be rinsed with clear water.
After the procedure, feeding strawberry beds need to zamulchirovat spruce or pine needles. This kind of mulch has antiseptic properties - protects against attacks strawberries pathogenic microbes and slugs.
When selecting a suitable mulch should take into account the composition of the soil and climatic features of the agricultural landscape.
Varieties of nitrogen application
The principles of organic farming ideal nitrogen fertilizers for strawberries find nutrient solutions on the basis of:
- infusion of mullein;
- chicken manure.
First Embodiment active mixture is prepared by diluting the infusion water, observing a ratio of 1:10, the second - 1:15. Fertilizer consumption has to be maintained at 1 liter per hive.
Among complex organomineral fertilizer strawberry suitable chlorine-free balanced compositions containing humate additive. Besides filling stock nitrogen in the soil, they are provided with the active layer it with macro- and microelements, ensuring normal growth and development of growing crops. The good performance is characterized by fertilizer "foppish".
How to prepare a fertilizer
Organo-nutritional composition for the inmates strawberry beds can be prepared independently of the 1 st. l. ammonium sulfate and 2 cup brew through cow manure. These components need to be dissolved in a 10-liter bucket of water. After thorough mixing, can be used to feed the resultant solution (the rate of 1 liter per bush). This species is able to enrich the nitrogen fertilizer even extremely depleted soil.
A beneficial effect on planting strawberries provide fertilizers. Nitrogen, which is part of carbamide (urea), well digestible feed cultures due to water solubility. It is used in dry form by making 1 tsp for 1 m² aisle or in solution form (3 tbsp. l / 10 l of water -. an amount sufficient nutrient mixture 1 m) for irrigation. Ammonium nitrate as a fertilizer for strawberries must be made for 1.5 h. l.
For the use of all types of nitrogen fertilizer has a rule: make early spring, when the awakening plants need to accelerate the microbiological processes in the soil.
