Urea (carbamide) fertilizer: application in the garden, instructions

Anonim

Urea is a fertilizer used by many gardeners when growing various types of vegetables. It is worth noting that it has another name - urea. Proper feeding with urea helps to improve the fruiting of plants and stimulates their development. However, before using such top dressing, you need to familiarize yourself with what urea is and how to use this fertilizer in the garden.

What is this

Carbamide, or urea, is a chemical compound with carbonic acid. Outwardly, humated carbamide looks like ordinary transparent crystals that are odorless.They dissolve easily in ethanol, ammonia and warm water. Grade B carbamide contains quite a lot of nitrogen and may have a white or yellowish tint.

Currently, urea fertilizer is used in various fields of activity. For example, in the medical industry, carbamide is used to create drugs that can remove water from the human body and relieve severe swelling. Also, the substance is often added to various sleeping pills.

Sometimes urea is used as a food additive to improve the flavor and taste of foods. Quite often it is added to chewing gum and baked goods.

However, urea is most commonly used as a fertilizer. The use of urea in agriculture allows you to increase the amount of nitrogen in the soil. This improves soil fertility and increases the yield of grown vegetables. Such a nitrogen fertilizer is characterized by increased activity and due to this it is quickly absorbed by plants.It is recommended to use it for feeding vegetable crops during pre-sowing preparation of the site or when the bushes begin to gain green mass. In summer, during the formation of fruits, you should not use urea, as this can significantly worsen the yield.

Pros and cons

Granular carbamide, like any other plant nutrition product, has its advantages and disadvantages. Benefits of urea as a fertilizer include:

  • increasing the rate of green mass formation;
  • increase in the amount of protein in almost all cereals that were fertilized with carbamide;
  • improve plant immune system and prevent pests;
  • low nitrate levels even after frequent feeding.

The use of urea does not have many disadvantages, but they should still be familiar with before applying the fertilizer. The disadvantages include the fact that:

  • if the dosages are not observed, serious burns may appear on the seedlings, which in the future will lead to the death of the bushes;
  • The temperature of the solution is much lower than the air temperature, so it should only be used on warm days;
  • Urea is not recommended to combine with other fertilizers.

How to breed urea

Urea liquid solution can be used to feed almost any horticultural or horticultural crop. Before using urea, you need to familiarize yourself with its varieties. There are two main markings:

  1. Marking "A". This brand is produced to create special feed additives for animals. Sometimes a top dressing with this name can be granulated to create a resin or glue.
  2. Marking "B". This carbamide fertilizer is granulated for feeding plants grown in the garden.

It is brand “B” that is used for breeding fertilizing fertilizer, since marking “A” can negatively affect the quality of the resulting crop. To create high-quality top dressing, you should familiarize yourself with the features of the preparation of the solution. At the same time, it is recommended to observe the correct proportions of urea, which depend on the plants being fed. For example, foliar feeding of potatoes with urea is carried out using a solution prepared from 50 grams of fertilizer and 10 liters of water.

To properly feed the potatoes, 3-4 liters of the prepared mixture is spent on each bush.

The optimal dosage of urea when creating a feed mixture for fertilizing shrubs and trees is 30 grams per 10 liters of water. The preparation of such a mixture is carried out in several successive stages. First, all the granules are poured with two liters of cold water and stirred until they are completely dissolved. After diluting the granules, add another 8 liters of liquid to the mixture.

How to apply top dressing

After reviewing the features of the preparation of the working solution, you should figure out how to carry out foliar feeding with urea. Instructions for use of this feed mixture will help improve the yield of vegetables in the future.

Feeding

Quite often, potatoes are fed with urea. It is recommended to do this during planting.However, some use this method during the cultivation of bushes. To do this, near the potato bushes, urea granules are dug in to a depth of about ten centimeters. In this case, it is necessary to observe the correct dosage. When adding granules to the soil, it must be remembered that 130 grams of the substance can fit in a two-hundred-gram glasses, 15 grams in a matchbox, and only 10 grams in a tablespoon.

If manure or any other organic fertilizer with a lot of nitrogen was added to the soil before applying urea, the dosage will have to be reduced by half.

Granules need moisture, so almost immediately after adding them to the soil, abundant watering is carried out. Under each bush you need to pour at least a liter of water.

Dry granules are often used during soil preparation for planting vegetables. It is customary to do such preparatory work in the fall during the digging of the site.In this case, about 150 grams of carbamide will have to be spent per square meter of the garden.

Irrigation

Urea with the addition of humates is an organic fertilizer that can be used to irrigate vegetable crops. There are various folk recipes for preparing a liquid for watering plants. For the treatment of shrubs and low trees, a very concentrated solution should be used. Therefore, to prepare a working mixture in 10 liters of water, you will have to add at least 350 grams of the substance.

Currants and other berries do not need such a concentrated liquid. In this case, to prepare the mixture, only 40 grams of urea is added to a ten-liter container with water. Vegetable crops need nitrogen fertilizers, so more concentrated mixtures are used for their irrigation. To create them, you will have to mix 10 liters of water and 200 grams of urea.

However, when using fertilizer such as urea in the garden, one must remember that it oxidizes the soil. Before using it, it is recommended to normalize the acidity of the soil and add about 400 grams of chalk to it.

Spraying

Many are wondering if carbamide can be used to spray vegetables. You can spray seedlings with such a solution, and there is nothing wrong with that. Spraying of potatoes and other vegetable crops is carried out in the evening or in the morning when there is no sun.

To prepare the urea solution, it is recommended to add 30-50 grams of top dressing to five liters of cold water. If no plant has yet been sprayed with mineral solutions, you can make the mixture more concentrated. To do this, 120 grams of urea is added to a ten-liter saucepan. About two liters of liquid should be spent on one plant.

You can use the prepared mixture not only to stimulate the development of seedlings, but also to protect them. The prepared spray liquid is able to destroy all pests on the bushes and protect plants from the most common diseases. It is best to use this solution against suckers, weevils and flower beetles.

Before spraying, be sure that there will be no heavy rains in the coming days. If it rains in the first two days after spraying, then you will have to process the seedlings again, as the urea will be washed off the leaves.

How to replace urea

Many are interested in whether one fertilizer can be replaced by another. Since carbamide contains a large amount of nitrogen, any other nitrogen mixture can be used instead.Sometimes, in the absence of urea, vegetables are fed with calcium, ammonium or potassium nitrate. You can also use diammophos or ammophos.

Conclusion

Currently, many gardeners use urea fertilizer. Before using urea, you need to familiarize yourself with the features of its use. To do this, you should study in detail the instructions for the use of top dressing with a detailed description and photo. You can also read reviews of vegetable growers who use urea every year.
