Can potassium fulvic acid and urea be applied together, and what is the dosage?

Hello,Ore sourcePotassium fulvic acidYes andUreaUsed togetherUrea is a good nitrogen fertilizer, so potassium fulvic acid can be mixed with fish protein, polyeffect, urea and other fertilizers.

1. Potassium fulvic acid and urea can be mixed in the mining institute

Mineral sources of potassium fulvic acid can be used and fertilizers (such as urea, ammonium sulfate, potassium dihydrogen phosphate.

potassium sulfate and other compound fertilizers) together, but it is necessary to pay attention to the compatibility ability of its mineral source potassium fulvic acid products;

Most chemical fertilizers are acidic after being soluble in water, but the general potassium fulvic acid is insoluble in acidic solutions, so there will be a corresponding flocculation limit if the cations in the fertilizer solution.

High will also cause flocculation, fertilization is recommended to choose sea food fertile water-soluble fertilizer.

Precautions

It is recommended to do a small batch experiment before mixing, if there is a flocculation and precipitation, it is recommended not to use it on drip irrigation or sprinkler irrigation, which is easy to cause the problem of clogging the drip irrigation belt or sprinkler irrigation belt.

However, there is no problem with flushing, because only humic acid is present in flocculation.

Or xanhumic acid and cation complex synthesis of macromolecular compounds, which will affect the fertilization effect, this complex.

It will also improve the utilization rate of nitrogen, phosphorus and potassium.

It can be flushed with urea.

Mineral potassium fulvic acid is a kind of soil synergistic fertilizer and soil dynamic regulator, which is chemically alkaline, and has a high activation functional group in the application to adjust the soil structure and water and fertilizer retention capacity. In use, it can be mixed with urea, paclobutrazole, fish protein fertilizer, etc.

Mineral potassium fulvic acid is mixed with urea, which can timely and effectively replenish the nitrogen, phosphorus and potassium components required for crop growth. Urea is a kind of fast-acting high-content nitrogen fertilizer, and the two fertilizers are mixed to work well, promote crop growth, and improve the photosynthesis rate of crops. Urea can be regarded as a kind of nitrogen fertilizer with a good effect of increasing production and income, and the combination with mineral potassium fulvic acid can also improve the absorption and utilization rate of mineral potassium fulvic acid.

Mineral potassium fulvic acid is used together with urea, which can be mixed evenly and sprinkled, or can be sprayed after water dissolving, it should be noted that the nitrogen content of urea is relatively high, and foliar spraying needs to pay special attention to concentration and dosage to avoid the possibility of fertilizer damage caused by excessive concentration.

Urea, also known as urea and carbaamide, is an organic compound composed of carbon, nitrogen, oxygen, and hydrogen, and is a white crystal. One of the simplest organic compounds, it is the main nitrogen-containing end product of protein metabolism in mammals and some fish.

As a neutral fertilizer, urea is suitable for a wide range of soils and plants. It is easy to preserve, easy to use, has little damage to the soil, is a chemical nitrogen fertilizer with a large amount of use, and is also the nitrogen fertilizer with the highest nitrogen content. Ammonia and carbon dioxide are used in industry to synthesize urea under certain conditions.

Urea is a highly concentrated nitrogen fertilizer, which is a neutral fast-acting fertilizer, and can also be used to produce a variety of compound fertilizers. No harmful substances remain in the soil, and there are no adverse effects after long-term application. Animal husbandry can be used as feed for ruminants.

However, if the temperature is too high in granulation, a small amount of biuret will be produced, also known as biuret, which has an inhibitory effect on crops. China stipulates that the content of urea biuret for fertilizer should be less than. When the content of biuret is more than 1%, it can not be used as seed fertilizer, seedling fertilizer and foliar fertilizer, and the urea content in other application periods should not be too much or too concentrated.

Urea is an organic nitrogen fertilizer, which can be absorbed and utilized by crops after being hydrolyzed into ammonium carbonate or ammonium bicarbonate by urease in the soil. Therefore, urea should be applied 4 to 8 days before the fertilizer requirement of the crop.

Urea is suitable for base fertilizer and top dressing, and sometimes also used as seed fertilizer. Urea is molecular before conversion, which cannot be adsorbed by the soil, and should be prevented from being lost with water; The ammonia formed after conversion is also volatile, so urea should also be deeply covered with soil. (A small part of the soil is dissolved in the soil solution in a molecular state, adsorbed by the soil through hydrogen bonding, and most of the other is hydrolyzed into ammonium carbonate under the action of urease, and then carbonic acid and ammonium hydroxide are generated.)

Then the ammonium ions can be absorbed by plants and adsorbed by soil colloids, and bicarbonate ions can also be absorbed by plants, so that urea does not leave any harmful components after being applied to the soil. In addition, urea contained in biuret can also be decomposed into ammonia and carbonic acid under the action of urease, the transformation of urea in the soil is affected by the soil pH value, temperature and moisture, and the soil has a neutral reaction, the higher the soil temperature when the water is appropriate, the faster the transformation; It takes 7 to 10 days for urea to be completely converted into ammonium nitrogen when the soil temperature is 10, 4 to 5 days when it is 20, and 2 to 3 days when it is 30. Ammonium nitrogen is generated after urea hydrolysis, and surface application will cause ammonia volatilization, especially on alkaline or alkaline soils, so the soil should be deeply applied when applying urea, and the paddy field should be deeply applied to the reducing layer.

Urea is suitable for all crops and all soils, and can be used as base fertilizer and top dressing, and can be applied in dry-paddy fields. Because urea can accumulate a large amount of ammonium ions in the soil, it will cause the pH to rise by 2 to 3 units, and urea itself contains a certain amount of biuret, and its concentration at 500ppm will inhibit the young roots and shoots of crops, so urea should not be used as seed fertilizer.

Potassium fulvic acid is a type of putrefaction. Acids used to raise flowers. This tends to be potash.

Note that it is better to have a reasonable ratio with nitrogen and phosphorus fertilizer. General potassium fertilizer is easy to lose, and it is enough to use fertilizer in small quantities many times. Nitrogen fertilizer grows leaves, potassium fertilizer strengthens the stem and resists disease, and phosphorus fertilizer promotes roots.

Since it is fertilizer, follow the principle of fertilization.

Question: I am a foliar spray, can I still spray it with water fertilizer?

Question: Okay, thank you.

You're welcome, I hope it helps.

Summary. Hello, glad for your question. The ratio of mineral potassium fulvic acid to urea is urea and mineral potassium fulvic acid combined with foliar spraying, urea can promote the faster and better absorption of mineral potassium fulvic acid by crop foliage, and the utilization rate of mineral potassium fulvic acid is also greatly improved.

The proportion of potassium fulvic acid and urea from mineral sources.

If you want to add urea to the grape seedlings, please ask the teacher how much urea should be used for 1000 catties of water.

The dosage of potassium fulvic acid per mu is 500-1000 grams. 1000 kg of water should be 30 kg of potassium fulvic acid and 2 kg of urea according to the proportion.

30 kilograms of mineral source potassium fulvic acid, 1000 kilograms of water, is the amount of potassium fulvic acid a bit large.

If you make a mistake, three thousandths is 3 catties of potassium fulvic acid and catty urea.

1000 catties of water, 3 catties of mineral source potassium fulvic acid, 2 catties of urea, is it so with the teacher.

Yes, dear.

Summary. Flush application or bottom application, plus 1 tael of mineral source potassium fulvic acid or 2 taels of biological source potassium fulvic acid per 40 kg of urea.

The ability of urea to penetrate the cell membrane of the leaf is very strong, and the permeability coefficient is close to that of water. Urea and potassium fulvic acid were applied with foliar sprays, which could promote faster and better absorption of potassium fulvic acid in the foliar surface of crops, and the utilization rate of potassium fulvic acid was also greatly improved.

Flush application or bottom application, plus 1 tael of mineral source potassium fulvic acid or 2 taels of biological source potassium fulvic acid per 40 kg of urea.

I'm going to rush how to match.

The dosage of potassium fulvic acid per mu is 500-1000 grams, and urea is determined according to the growth.

Oh, more urea and less urea, it's fine.

It's okay, it doesn't matter.

Can potassium fulvic acid and urea be applied together, and what is the dosage?

The role of potassium fulvic acid from mineral sources 1, the root system is developed, the germination rate is improved, and the transplanting is prosperous. 2. Improve fertilizer utilization rate, disease resistance, phosphorus and potassium and nitrogen fixation, and improve fertilizer utilization rate by more than 50%. 3. Improve the ability to resist cold and drought.

4. Promote the absorption of micro-fertilizer, prevent deficiency of nutrients, and improve quality. 5. Improve the soil, adjust the pH value, purify heavy metals, and alleviate the damage of pesticides and fertilizers. 1. Together with urea, we know that the utilization rate of urea is very low, and the utilization rate of urea in China is only 30.

It can inhibit urea mold and digestive enzymes, increase the utilization rate of urea to 70%, and extend the duration of the effect to 100 days. It can not only improve the utilization rate of chemical fertilizers, but also dissolve phosphorus and potassium. 2. For example, when we plant tomatoes, we will use some, sheep manure, chicken manure or something of the hole skin, these manure will acidify or salinize the soil after high temperature stuffy shed, plus we use phosphate fertilizer and potassium fertilizer when we use crops, and many unused ones have been fixed.

At this time, we use some yellow rot when flushing fertilizer.

Summary. Hello, there are three kinds of potassium fulvic acid in the mineral source: powder, granules and water-soluble fertilizer, which are used as base fertilizers, and the granular mineral source can be sprinkled with compound fertilizer for ploughing and land preparation.
