The acidity and alkalinity of plant ash water, whether plant ash is acidic or alkaline

Grass ash K2CO3 is an alkaline fertilizer, which can provide crops with a variety of nutrients mainly potassium. In addition to this, plant ash has the following uses:

1. Prevention and control of fruit tree root rot. Take the soil near the fruit tree with root rot, remove the rotten roots, cover it with plant ash, and then cover it with new soil.

2. Control aphids. The grass ash is sifted, sprinkled on the aphid body in the morning when the dew is not dry, and sprinkled again every 3-5 days, and the control effect is better.

3. Improve the insecticidal effect of trichlorfon. For leaf mites, scale insects, aphids, etc., every 1 15 hectares (1 mu) with kilograms of plant ash, plus % trichlorfon powder kilograms, mixed after the effect of powder is good.

4. Store jujubes. Spread a layer of 7-10 cm of plant ash at the bottom of a clean jar or other utensils, spread a layer of kraft paper or 3 layers of newspaper on the upper layer, and place it in turn according to a layer of jujube and a layer of plant ash, and the thickness of the top layer of plant ash should reach 12-16 cm, and it can be placed in a cool place.

5. Humidity, waterlogging and disease prevention. In summer, the fruit trees are waterlogged, which is easy to cause root rot and death, and a layer of 10 cm thick plant ash is sprinkled in the tree tray to prevent the fruit trees from being waterlogged, and provide potassium fertilizer for the fruit trees to improve the quality of the fruits.

Grass ash K2CO3 is an alkaline fertilizer.

Grass ash K2CO3 is an alkaline substance.

The main component of plant ash is potassium carbonate, potassium carbonate is a strong alkali and weak salt, the hydrolysis is alkaline, and the aqueous solution is alkaline.

Grass ash is alkaline.

Grass ash is the ash left over from plant incineration, and the potassium content in it is quite high, and when used, plant ash can be absorbed by plants without fermentation. But do not directly bury the plant ash in the soil or sprinkle it on the surface of the pot soil, because the plant ash is alkaline, and the alkaline is very large, which can easily lead to the situation of yellow leaves and dead seedlings in plants.

It is necessary to put the plant ash in a large container, seal it with water, and soak it in the sun for more than 24 hours, so that you can water the flowers directly or spray it on the leaves.

Ingredients

The main component of plant ash is potassium carbonate (K2CO3) with a relative molecular weight of 138. Grass ash fertilizer is the ash of plants after burning, so it is the mineral element contained in all plants, and almost all plant ash contains it.

Among them, the most abundant is potassium, which generally contains 6 12% potassium, of which more than 90% is water-soluble and exists in the form of carbonate; followed by phosphorus, which generally contains; It also contains calcium, magnesium, silicon, sulfur and micronutrients such as iron, manganese, copper, zinc, boron, molybdenum, etc.

The nutrient content of ash of different plants is different, and the potassium content of sunflower straw is the highest.

Summary. If you add too much, the plant ash will be completely lost, and it will become carbon dioxide and water.

How plant ash becomes acidic.

Hello. You can mix plant ash with water and add acetic acid.

Mix it up and it can become acidic.

Grass ash can be used with acid.

The ash is alkaline, so we can add acid.

Can be used with acids.

We add some acetic acid to make it acidic.

Acids and plant ash do not react chemically.

It can be a chemical reaction.

But when you add an appropriate amount of acid, it is also acidic, and there is also the original plant ash, and the ingredients still have a role.

After the chemical reaction, it was said to be useless.

After the chemical reaction, some of it is useless, but if you add the right amount of acetic acid, it will make it acidic and have the composition of plant ash.

Because of chemistry, there is a balance.

That's not what it means, I can't add too much.

If you add too much, the plant ash will be completely lost, and it will become carbon dioxide and water.

Okay thank you. If you don't mind, move your little hands, give a thumbs up, and wish you a happy life.

to give. Okay, if you have any questions in the future, you can click on my avatar to consult.

Grass ash is an alkaline fertilizer that has the ability to neutralize acidic soils. Grass ash mainly increases potassium fertilizer, and if the plant ash is mixed with bean cake fertilizer, the fat of bean cake can be precipitated. Grass ash not only has a certain insecticidal function, but also can promote the fermentation of bacteria and promote the decomposition of organic matter.

If the right amount of plant ash is mixed with composting, it can help the organic matter to decompose. Grass ash is good for drought and frost resistance, so plant ash is a very good fertilizer.

Precautions for the use of plant ash:

1. Grass ash cannot be mixed with organic farm fertilizer (human manure, manure, compost fertilizer, etc.) and ammonium nitrogen fertilizer, so as not to cause nitrogen volatilization loss; It should also not be mixed with phosphate fertilizer, so as not to cause phosphorus fixation and reduce the fertilizer efficiency of phosphate fertilizer.

2. Because the plant ash is alkaline, it is advisable to apply clayey soil, acidic or neutral soil.

3. More than 90% of the potassium contained in the grass ash is soluble in water and is a fast-acting potassium fertilizer. According to this characteristic, plant ash can be used as extra-root top dressing, that is, foliar spraying with a concentration of 1% plant ash leachate.

4. Priority crop plant ash is suitable for all kinds of crops, especially for potassium-loving or potassium-loving chlorine crops, such as potatoes, sweet potatoes, tobacco, grapes, sunflowers, sugar beets, etc. Grass ash is used in potatoes, not only for soil application, but also for coating potato tuber wounds, which can be used as seed fertilizer and prevent wound infection and rot.

How to use plant ash:

Grass ash is a fertilizer that is often used. It is composed of plant straw, firewood grass, dead branches and leaves and other residues after combustion, mainly containing potassium. Grass ash is gray-black or black, not nitrogen and organic matter, only ash and a large number of trace elements, the most of which are potassium and calcium.

Because the form of potassium in plant ash is mainly potassium carbonate, followed by potassium sulfate, a small amount of potassium chloride, more than 90 can be soluble in water, high effectiveness, so it is an ideal fast-acting potassium fertilizer.

Grass ash is an alkaline fertilizer, which can not be mixed with ammonium nitrogen such as sulfate and nitrate, and can not be mixed with human feces and livestock feces, otherwise it will cause rapid volatilization of nitrogen and become ineffective. Grass ash is suitable for all kinds of soils except saline-alkali soils, especially for acidic soils. It can be used as base fertilizer and top dressing, generally with a maximum of about 50-100 kg per mu, and mixed with wet soil before use, but not too much water, otherwise it will cause nutrient loss.

Grass ash can be mixed with culture soil in a certain proportion in potted flowers, which not only increases potassium fertilizer, but also makes the potting soil loose, drains well, and is conducive to roots. Regardless of cuttings, seedlings, and potted flowers, plant ash can be used.

The main ingredient of plant ash is potassium carbonate, so it is alkaline. It is moderately alkaline, which can neutralize the acidity of the soil, improve the soil, and help the growth and development of plants. In addition, plant ash is also rich in minerals, which can promote the growth of plant roots.

Grass ash is alkaline, but not very alkaline. Grass ash is one of the important nutrients for planting flowers and trees and ensuring that seedlings grow well.

It is alkaline, and the alkalinity is not large, because the alkali of plant ash is a weak alkali, and the alkalinity is very low.

Grass ash contains potassium carbonate, and there is no objection that the aqueous solution of potassium carbonate is alkaline.

But in fact, the alkaline nature of plant ash, potassium carbonate is not the main **. The main ** is the ash in the plant ash, that is, calcium oxide, magnesium oxide and other alkaline oxides. The aqueous solution of these substances is much more alkaline than the potassium carbonate solution.

The main component of plant ash is potassium carbonate, the chemical formula is K2CO3, and the aqueous solution is alkaline.

Grass ash contains potassium carbonate, which is alkaline.

Grass ash is alkaline.

The chemical composition of plant ash is K2CO3, and the acid corresponding to carbonate is a weak acid (H2CO3 carbonate), and the weak acid group is ionized after being dissolved in water. Carbonate ions react with hydrogen ions ionized from water to form bicarbonate ions and hydroxide ions, which in turn react with hydrogen ions ionized by water to form carbonic acid and hydroxide ions. The hydroxide ion is alkaline, and the potassium ion is not hydrolyzed, so the plant ash solution is alkaline.

Grass ash is a good inorganic agricultural fertilizer, rich in nutrients, such as potassium, phosphorus, etc., which is very beneficial to the growth of crops.

Grass ash is alkaline, if it is planted with vegetables or plants that like acidic soil, you can not use plant ash as fertilizer, so as not to damage the growth of plants, such as sweet potatoes, potatoes, greens, etc., it is suitable to use plant ash as fertilizer.

How to use plant ash

1. Use alone.

Grass ash is generally used alone. It can not be mixed with organic farm fertilizer and ammonium nitrogen fertilizer, so as not to neutralize the acid and alkali and volatilize the ammonia, thereby reducing the fertilizer efficiency; It should also not be mixed with phosphate fertilizer, so as not to cause phosphorus fixation and reduce the fertilizer efficiency of phosphate fertilizer.

2. Soil application.

Soil application should be cohesive, acidic or neutral soil. Soil application can generally be used as base fertilizer, seed fertilizer and top dressing. When making base fertilizer and seed fertilizer, the amount of fertilizer should not be too large and should be isolated from the seeds to prevent seed burning.

The amount of slippery dust per mu is generally 50-100 kg, which is suitable for hidden socks. When topdressing, it is advisable to apply intensively, using strip application and hole application, with a depth of 8-10 cm, and covering the soil after application.

3. Top dressing outside the roots.

The potassium contained in plant ash is more than 90% soluble in water, which is a fast-acting potassium fertilizer. According to this characteristic, it can be used as extra-root top dressing, that is, foliar spraying with charcoal ash leaching solution with a concentration of 1%.
