Can urea be used as foliar fertilizer for flowers? What is the appropriate concentration of urea as

Yes, and this will allow the plants to grow faster and have a higher survival rate.

Depending on what kind of flowers are used, the biggest effect of urea is to make the branches and foliage more lush.

Urea can be used as a foliar fertilizer for many crops, and flowers are also commonly used. I first used urea as a foliar fertilizer 30 years ago when I was raising silkworms and mulberry seeds. In addition to the root application of farm fertilizer, mulberry leaves are rarely buried with chemical fertilizer, because the cost of chemical fertilizer is high, and the mulberry leaves with chemical fertilizer are easy to get diseases.

Can urea be used as foliar fertilizer for rhododendrons? What is recommended for foliar fertilizer and how to save it after a foliar burn.

Hello friend, let me tell you about the ingredients of the two and you will understand:

Foliar fertilizer components.

Macroelements: nitrogen N, phosphorus P, potassium K

Trace elements: calcium Ca, magnesium MG, iron Fe, boron B, manganese Mn, copper Cu, zinc Zn, molybdenum Mo, chlorine Cl

Bulking inducer, organic nano-potassium, composite biological bacteria.

Additional Ingredient: Active Ingredient Humic Acid.

Urea composition. Urea, also known as carbamide, is a white crystal. One of the simplest organic compounds. It is a neutral fast-acting fertilizer with high nitrogen content, low biuret content, colorless, tasteless, odorless, soluble in water, easy to apply, uniform particles, full and round, and less dust.

If you want to top dressing crops, I think you can use Dehua Xinlu foliar fertilizer to mention a large number of elements, trace elements and other components, and trace elements are absorbed by crops in the situation of multiple chelation.

Foliar fertilizer is better, but it still depends on what it is used for.

Urea is a compound fertilizer with high nitrogen content, the chemical name is carbon amide, containing carbon, oxygen, hydrogen, nitrogen 4 chemical elements, good instant solubility, under normal circumstances, can not be directly absorbed and utilized by cropsIt needs to be hydrolyzed into ammonium carbonate or ammonium bicarbonate before it can be absorbed.

In practical production applicationsUrea is mostly used as a base fertilizer and top dressing. Bottom fertilizer is usually not used alone, but will be mixed with potassium fertilizer to fully supplement nutrients, and top dressing is used more. When topdressing, it is mostly used for sprinkling, which can be used before rain or before watering.

Let's be honest,The use of urea as a foliar fertilizer is uncommon and may only be used when the leaves are yellowing and there is a severe nitrogen deficiency. This is because excessive concentration will burn the young parts of the crop, and there are many foliar fertilizers on the market, which have this function and are safer.

StillIf you have to insist on using urea as foliar fertilizer, you should keep in mind the following two precautions for concentration and use time:

A safe urea foliar fertilizer concentration of 500 times is a safe ratio, that is, 1 kg of urea to 500 kg of water. The reference here is to the urea content that is commonly found in the market. Usually the sprayer we use is 20kg capacity, then you can add 40g of urea, stir evenly, and then you can carry out foliar spray.

Foliar spray urea solution should pay attention to the use time of urea high nitrogen content, and when the temperature is too high, it is easy to burn the leaves. It is recommended that the prepared urea solution be sprayed in the early morning or evening, and never sprayed on the foliar surface at noon.

In order to improve the utilization of urea, it is best to water the urea solution before spraying it on the foliar surface to increase root viability and faster absorption.

StillThe use of urea solution as foliar fertilizer is a means of rapid nutrition supplementation after crops are extremely deficient in fertilizer and have shown obvious symptoms of yellowing and nitrogen deficiency.

If this is not the case, it is recommended that you use potassium dihydrogen phosphate or nitrogen, phosphorus and potassium foliar fertilizer or medium and trace element foliar fertilizer on the market.

Urea can be used as flower fertilizer, it is a fertilizer with the highest nitrogen element, can maintain foliar luster, can also adjust the amount of flowers, suitable for all crops and soil, can be used as base fertilizer and top dressing, sometimes also used as seed fertilizer. When urea is used as flower fertilizer, it cannot be used as a single fertilizer, and should be used in combination with other organic fertilizers or compound fertilizers, so as to meet the growth needs of flowers and plants.

Urea is used as flower fertilizer.

Urea can be used as flower fertilizer, suitable for all crops and soil, suitable for base fertilizer and top dressing, and sometimes used as seed fertilizer, after use, it can make the branches and leaves grow very luxuriantly.

Urea is directly used as flower fertilizer.

Urea can not be directly used as flower fertilizer, its concentration is too high to easily burn the roots of the plant, dilute it with water before using a good nucleus, the ratio is about 1:5000, urinary lead will make the seeds lose the ability to germinate, and may even harm the seedlings, so do not use urea on seedlings and seeds.

What kind of flowers are urea suitable for.

Urea is now a fertilizer with the highest nitrogen content, which can be applied to most plants, such as pothos, fortune tree, sunflower, etc., can maintain foliar luster, and can also adjust the amount of flowers, such as peony flowers, roses, white palms, etc.

Urea is used as flower fertilizer.

1. To make urea fertilizer, you can use a large beverage plastic tank to seal the urea, let it ferment to three months before you can use it, and use it with water according to the amount of water, generally with 50% of the water friends round digging on it.

2. When urea is used as flower fertilizer, it cannot be used as a single fertilizer, but should be used in conjunction with other organic fertilizers or compound fertilizers, so as to meet the growth needs of flowers and plants.

Urea is used as flower fertilizer.

Urea can be used as flower fertilizer, suitable for all crops and soils, can be used as base fertilizer and top dressing, sometimes can also be used as seed fertilizer, after use, it can quickly accompany the growth of branches and leaves.

Urea is directly used as flower fertilizer.

Urea cannot be used directly as a flower fertilizer. Its high concentration can easily burn the roots of plants. Dilute with water in a ratio of approximately 1:5000 before use. Urea can make the seeds lose their ability to germinate and may even harm the seedlings, so do not use urea on the seedlings and seeds.

What kind of flowers are urea suitable for.

Urea is currently the fertilizer with the highest nitrogen content. It is suitable for most plants, such as pothos, rich tree, purple-backed geranium, etc. It can maintain the luster of the leaves and adjust the amount of flowers, such as peonies, roses, white palms, etc.

Urea is used as flower fertilizer.

1.To make urea fertilizer, you can seal the urea in a large plastic beverage tank and let it ferment for three months before it can be used. Add water according to the amount when using, generally 50% water.

2.When urea is used as flower fertilizer, it should not be used as a single fertilizer, but should be used in combination with other organic fertilizers or compound fertilizers to meet the growth needs of flowers.

<> urea can fertilize the flowers. Precautions for the use of urea: If the urea concentration is too high, it is easy to burn the roots of the rotating plant, dilute it with water before use, and the proportion is 1:

around 5000; After pouring urea, the beam bridge cannot be watered directly; Urea can make the seeds lose their ability to germinate, and may even harm the seedlings. Urea cannot be used as a fertilizer alone, but should be used in combination with other organic fertilizers or compound fertilizers.
