What is urea as a fertilizer. Urea (fertilizer): instruction

Many gardeners, gardeners and flower growers today can not imagine how to manage without fertilizers. Thanks to complex top dressing, growth stimulators grow faster, form beautiful, lush foliage, strong root system, less exposed to diseases. In this case, the main thing is not to overdo it and to know exactly which fertilizers are suitable for anyone, so that later there are no unpleasant surprises.

What is urea?

As fertilizer, urea is widely used for activating growth, obtaining abundant harvests, maintaining plants in a presentable state. Nitrogen is needed for both vegetable and ornamental crops. It is present in the protein and promotes rapid growth. With a lack of nitrogen plants give little shoots, branches and leaves become thin, small, light green or yellowish. Flower buds can fall off, fruits do not tie.

What is urea? As a fertilizer it is used for private use. Urea is very concentrated, it contains about 45% of nitrogen. It can be called a universal fertilizer, suitable for all types of plants. In appearance, these are transparent or white granular beads, perfectly soluble in water and odorless. Carbamide may increase hygroscopicity with increased humidity. Used as a fertilizing for agricultural plants in neutral soils urea (fertilizer).

Instructions for use

Carbamide can be used on all types of soils, even waterlogged, because it is well fixed by the soil and is not washed out by precipitation, such as, for example, ammonium nitrate. Urea is used both as a fertilizer and as a main fertilizer. For vegetable crops, it is possible to make carbamide before planting, as well as top dressing during the growing season in a dose of 5-10 g per 1 m ² . Before flowering it is necessary to pour a solution of 50 grams per 10 liters of water, its approximate consumption is 3 l / 100 m ² . For decorative and fruit-berry bushes and trees, urea fertilization is possible immediately after flowering and again after about a month with a solution of 30 g / 10 liters of water.

Method of application of urea

Each fertilizer has its own characteristics, which must be taken into account before using it for its intended purpose. Ammonium carbonate decomposes very quickly in the air, it follows that surface application of urea is ineffective. This is money thrown to the wind, because the plant will not receive the substances necessary to it. Agrotechnicians recommend using urea in conditions of protected soil. After applying fertilizer, it must immediately be embedded in the soil, only this way it is possible to prevent losses of gaseous ammonia. It is necessary to know what urea is, like fertilizer, it is quickly washed out by sediments, so it is most effective to bring it into the root of the plant in the form of a solution.

Protection of bushes and trees

Carbamide is used not only as a fertilizer, but also as a remedy for pests. As soon as warm spring days come, immediately use a urea solution to fight such wintering insects as weevils, aphids, coffins, etc. This procedure should be done before the buds swell. Prepare a pest control agent is very simple, for this, in 10 liters of water, dilute 0.5 liters of a concentrated solution of the drug.

Urea also protects plants from purple patchiness and scab, spraying is carried out in autumn, when the leaves start to fall off. You need to process all the leaves - both fallen, and the one that remained on the bushes and trees. The solution is prepared the same as for destroying pests.

Top dressing of indoor plants

Absolutely all plants need top dressing, but you need to think carefully before using such an additive as urea (fertilizer) for domestic green pets. The use of nitrogen for indoor plants is necessary, because it allows the creation of a lush crown, to accelerate growth, to prevent yellowing and falling leaves. Urea is very concentrated, so its use should be approached with great care. If you lose with the dosage, you can lose your pet or spoil his appearance.

It is necessary to understand what urea is. As a fertilizer it is suitable for creating lush, succulent foliage. And for beautiful flowering plants, nitrogen is not so useful, since its excess slows down the formation of buds. Bulbous (hyacinths, hippeastrums), wood (oranges, ficuses, lemons), rhizome (irises, callas) from the first days of life require nitrogen fertilizing, so they can be fertilized with carbamide without any fear. But tuberous (caladium, gloriosus) should be fed after the appearance of the first leaves. Urea as a fertilizer for indoor plants is used as a solution. The preparation is prepared at the rate of 20 g per 10 liters of water, enough for 10 m ² .

Top dressing for vegetable and fruit-berry crops

Urea is suitable for the fertilization of almost all types of plants, especially it is effective in the period of vegetative growth. However, it should be remembered that for different crops, it is necessary to concentrate to a different degree, such as urea, fertilizer. Application for garlic, onion, cabbage, potato, pepper and tomatoes is possible at a concentration of about 20 g of carbamide per m ² . Under the peas and cucumbers fertilizer is applied in the calculation of 7 g / m ² .

Tomatoes, strawberries, cabbage and cucumbers can be fed occasionally with a solution of 25 g / l, and twice-reduced carbamide concentration before budding buds should be watered gooseberries, currants and other fruit and berry bushes. Urea contributes to the formation of a beautiful crown, so it is recommended to make it under apple trees (230-250 g), plums and cherries (110-150 g). Carbamide can be sprinkled on the hole, and then it is well poured with water. Allowed and top dressing solution, but exclude watering can not.

If you compare urea with other nitrogen fertilizers, for example ammonium nitrate, then it largely benefits: it accelerates growth as much as possible, is suitable for foliar dressings and, at normal concentration, does not completely burn leaves. Proper use of carbamide not only improves the appearance of plants, but also contributes to obtaining a rich harvest.
