Urea for tomatoes
Content:
Tomatoes need nutrients for normal growth and development. One of the main nutrients, without which plants will not grow at all, is nitrogen. There are many fertilizers, both mineral and organic, containing nitrogen. Today we will talk about one of them, namely urea. Tomato urea has major benefits when diluted and used correctly.
Urea for tomatoes: description and composition
Urea is a mineral fertilizer. Has the appearance of white granules, odorless. It contains nitrogen, approximately 50%. The bacteria in the soil decompose urea, turning it into ammonium carbonate, which is well absorbed by tomatoes.
The main Benefits application urea for tomatoes:
Accelerates plant growth.
Urea for tomato seedlings makes plants strong.
Helps the plant to become more resistant to diseases and pests.
Increases the protein content of fruits.
With the correct dosage, it does not accumulate in fruits and soil.
It dissolves well in water.
Can be applied at any time during the season.
Disadvantages of using urea
In the air, part of the nitrogen evaporates in the form of ammonia, so fertilizers must be embedded in the soil or dissolved.
At high concentration, it burns plant roots.
Acidifies the soil.
Cannot be mixed with other mineral fertilizers.
Top dressing of tomatoes with urea: terms
Urea for tomatoes is used both in dry and liquid form. You can apply it under the bush itself or spray the ground part of the plant.
Urea is introduced into the ground before planting the plant at a dosage of 3 grams per hole. Mix well with the ground so that the granules do not remain on the surface. You need to make it in two or three days so that the urea has time to decompose and does not damage the roots of the seedlings. ash or lime can be added to prevent soil acidification.
Two to three weeks after planting, you can water the tomatoes with a urea solution.
The last time you can fertilize during fruiting.
The rest of the time, feeding should be done if the plant shows signs of a lack of nitrogen. You do not need to feed the plant with this fertilizer constantly, since nitrogen affects the growth of the green mass of the plant. But for the formation of flowers and ovaries, it is not needed.
How to dilute urea for feeding tomatoes. Root and foliar feeding with urea of tomatoes
When fertilizing plants with urea, the most important thing is to observe the correct dosages. Urea for tomatoes is diluted in certain proportions.
When applying dry granules to the soil, take 20 grams of fertilizer per square meter.
To prepare a solution for root feeding, take 30 grams and dilute in 10 liters of water.
To prepare a foliar solution, you need to take 15 grams and dilute in 10 liters.
Errors when using urea
Excess dosage. May cause burns, nitrate buildup.
The use of urea in acidic soils. The earth is acidifying even more.
Fertilize plants on dry soil. The soil must be moistened.
Leave dry on the soil surface. Since some of the nitrogen will evaporate as a gas.
Conduct feeding constantly. Use urea no more than 2-3 times per season.
For foliar dressing, use the same dosage as for root dressing. The concentration should be lower.
