This vegetable has long been grown in Russia, is one of the important products in the preparation of a huge number of dishes. Previously, cabbage was fertilized with organic matter, but today, after planting it in the ground, more and more spraying is carried out with agrochemicals, which allows getting good yields from small areas. Many gardeners do not trust mineral supplements and prefer to feed it with natural means. They believe that vegetables are saturated with nitrates, which have a bad effect on health. Opinion is fundamentally wrong. After all, with proper use of the compounds are no more dangerous than organic fertilizer. They are also useful not only to pour into the wells, but also to splash against pests, although vinegar, ammonia and other special means are more suitable for the purpose of saving the plant.

Do i need top dressing white cabbage planted in the garden?
To answer the question whether to feed or not, we should recall biology and chemistry, the order of plant nutrition and their growth. Nutrient components fall from the soil composition, dissolved in water, pass through the stem, penetrate the leaves. Organic substances are created from exposure to sunlight and water, carbon dioxide and mineral components.which are needed for growth. From them and formed cells - the plant grows. The process is called photosynthesis.
Substances consumed by the roots of the earth, are divided into macro - and micronutrients. Most plants need:
- nitrogen;
- phosphorus;
- potassium;
- sulfur;
- magnesium;
- calcium;
- gland.
In the trace elements the plant needs less, but they are necessary for normal development. This group should include:
- boron;
- silicon;
- manganese;
- copper;
- zinc and others
Without nitrogen and phosphate additives, cabbage will slow down in growth, foliage will change its shade. Lack of calcium will negatively affect the entire development of the plant, which will remain small. A copper-free vegetable will die at the seedling stage. So it turns out that a normal harvest can be achieved if you feed a culture transplanted into the soil in a timely and correct manner. So if you want the stalks to be plump and the heads are strong, you should definitely fertilize the plants.
It’s still important to remember that fertilizers should be used in a timely manner. For example, from the beginning of seed germination and before foliage formation, phosphorus is most needed for a plant. And as soon as the root system begins to develop, it should be sprayed with nitrogen and potassium. But at the time of aging there is a need for nitrogen, potassium and phosphorus at the same time. Of course, cabbage care is a painstaking task.
In short, for the entire growing season, the vegetable must perform three to four supplements in order to achieve a good harvest. The first two (mandatory) are in the initial stage of growth, the third and fourth (if necessary) are performed in June and August, respectively.
Types of fertilizers for proper fertilizer seedlings
Seed transplanted in the spring in the open ground must be fed at least twice. The first procedure is carried out a couple of weeks after planting, the second - at the initial stage of the formation of the fetus (after picking - required).
For the first feeding use potash, phosphorus and nitrogen fertilizer compositions at the rate of two hundred grams per hundred area. This is necessary to speed up the setting of a head of cabbage. But if organic matter, compost or humus were used for fertilizing the soil, then five hundred grams of ammonium nitrate should be added to each planting area.The second time it is necessary to process the days after twenty, for which it is necessary to water chicken droppings and mullein, likes vegetable and slurry.
Nitrogen, well podsypat under the root for the formation of the fetus
This group may include the following drugs:
- ammonium nitrate. It looks in the form of crystals of a dirty white color. The price of fertilizer is acceptable, the composition contains more than thirty percent of the nitrogen available to plants. Fertilizer composition is considered the most concentrated of the entire group. Applying it It is not recommended to exceed the dosage, so that the culture does not accumulate excess nitrates in itself;
- ammonium sulfate. These are salts of sulfuric acid. In appearance, the fertilizer represents white crystals, contains about twenty percent of nitrogen and a sufficient amount of sulfur. To make it at the rate necessary in the amount of one hundred and fifty percent of the nitrate to give the plants the right amount of nitrogen. But at the same time, remember that this fertilizer can increase the acidity of the soil compositionthat is not very desirable. And it is not necessary to spray the plant to get rid of pests;
- urea. These are ammonium salts of carbonic acid. White crystals contain up to forty six percent of nitrogen, which entails a decrease in the additional feeding rate by one and a half times.
Potash need for growth head
Cabbage, like Bulgarian pepper, is in great need of potassium, which is necessary for the formation of roots and the development of the aerial parts, so that the head can be tied, especially at an early stage of development. Otherwise the plant will be tall, but empty. It performs an important function in the transfer of organic compounds. You should always remember about this and feed the vegetable so that it forms a head with potassium-containing compounds:
- potassium chloride. In its pure form, it is represented by white crystals, resembling ordinary salt. In nature, in this form it is rare, but the natural version is distinguished by reddish tones. Available potassium in the composition - about sixty percent. Chances of soil acidification are high;
- potassium sulfate.These are potassium salts of sulfuric acid, containing up to fifty percent of the component. In most cases, the composition is used for chlorophobic crops, which do not include cabbage. It is possible to apply as top dressing structure.
Phosphoric, chemicals for processing at the end of the growing season
Phosphorus is not very necessary for cabbage, but it is not recommended to ignore its use. It plays an important role at the time of heading and the collection of nutrients at the final stage of the growing season. Superphosphate treatment is most often used. The compositions can be of two types, according to the amount of phosphorus, so it is necessary to check the packaging.
Natural fertilizers - the ability to feed and pest control
Culture responds well not only to fertilizers purchased in the store, but also to nutritional formulations made according to popular recipes. They also help the plant to form a large and strong head.
Sprinkle with manure - accelerate growth
This is one of the best options, especially if it is a white or color variety. Pre-manure is diluted with water at the rate of 1 to 5.The first time such a composition can be used two weeks after the seedlings are transferred to unprotected soil. After the procedure, the feed beds must necessarily spud. The second feed is performed before the formation of the ovary. But in this case, it is recommended to add wood ash in the amount of forty grams to the slurry.
The third time, manure is applied through a three-week interval after its second application. Watering with manure also allows you to save the plant from pests and save you from further trouble.. It is good for this to also sprinkle liquid ammonia, this is both protection and fertilizer.
The use of yeast helps to save from diseases
They contain a lot of useful components, vitamins and amino acids. Such an additive will help the seedlings fight diseases and it is good to transfer the transplant, we don’t need black spots on the leaves. This activates the development of the root system, improves the overall soil composition.
Yeast feeds three weeks after the introduction of the first feeding composition. Two hundred grams of dry yeast is diluted with a liter of warm water, a teaspoon of sugar, infused for two hours. Then the whole mass flows into a bucket of water. Consumption of the resulting composition should be from three to four hundred grams per plant;
Urea, popular source of nitrogen
Chemical compound, originally derived from the product of human activity. Today, urea is produced from mammalian proteins and individual fish individuals. With this feed, the plant gets the right amount of nitrogen, gaining more quickly in green mass. Before dressing should be thirty grams of urea diluted in a bucket of water. Under a single plant poured half a liter of the composition.
How to process cabbage before planting?
As soon as the saplings form two or three leaves, it is allowed to transplant it into an open garden bed. For its good adaptation, you should begin gradual tempering in advance.. In addition, the seedlings are fed with humate solutions or mineral fertilizers are used, of which Agricola and Kemira can be considered as examples.But they do this only if the soil composition contains a small amount of useful elements. As a preventive measure against harmful parasites, spraying the leaves and dusting the beds with tree ash are performed. This will protect the plant from pests such as slug, flea and caterpillar.
How to water after planting in open ground
Water culture should be carefully, observing some interval in a couple of days during the first two weeks. Water consumption for each square of the plot should be from seven to eight liters. Then the number of procedures can be reduced to once a week, pouring ten to twelve liters per square meter of beds.
Often, water treatments are combined with the application of fertilizers. This helps the root system better assimilate the beneficial components entering the soil.
It should be noted that the application of fertilizers should be performed on cloudy days or in the evenings, combining them with abundant watering.Compliance with all recommendations will help you grow a rich harvest of this tasty and healthy vegetable.
