What is the main ingredient of plant ash?

The main component of plant ash is potassium carbonate. Potassium carbonate is a strong alkali and weak salt, which is hydrolyzed in water to produce oh- ions, and plant ash is a kind of farmhouse potash fertilizer widely used in rural areas. The main component of plant ash is potassium, which is an organic fertilizer rich in potassium, calcium and phosphorus, and also contains a small amount of boron, aluminum, manganese and other trace elements.

The main component of plant ash is potassium carbonate (K2CO3), which is an organic fertilizer rich in potassium, calcium and phosphorus, and also contains a small amount of trace elements such as boron, aluminum and manganese. K2CO3 is a strong alkali and weak salt, which is hydrolyzed in water to produce OH- ions, and the mixing with nitrogen fertilizer can easily lead to the decline of nitrogen fertilizer efficiency.

Plant ash. The main ingredient is potassium carbonate.

The most abundant of these is potassium.

Generally, it 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. When the same amount of potassium was applied to plant ash, the fertilizer efficiency was better than that of chemical potassium fertilizer. Anhydrous is a white granular powder, and the crystalline product is a white translucent small crystal or particle, odorless, with a strong alkaline smell, it is a kind of inorganic farm fertilizer with extensive and low cost, complete nutrients and obvious fertilizer efficiency.

The main component of plant ash is potassium carbonate (K2CO3) with a relative molecular weight of 138.

Hello, it is calcium carbonate, which is generally used externally, or to stop bleeding, which is very commonly used, such as paracaust ash.

The main component of plant ash is potassium carbonate (K2CO3).

The relative molecular weight of plant ash is 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.

The role of plant ash:

1. Grass ash is a very high-quality alkaline potassium fertilizer and medium and micro fertilizer, which contains a variety of trace elements required for plant growth, which has the effect of promoting crop growth, development and maturity, improving the quality of agricultural products, and increasing yield. Note that plant ash is an alkaline fertilizer, which usually cannot be mixed with acidic fertilizer to avoid chemical reaction and reduce fertilizer efficiency.

2. It can promote the formation of plant roots and enhance the ability of root system; Cultivating strong seedlings and promoting reproductive growth; Promote the ripening of orange fruits; It has the effect of inhibiting and assisting some pests and diseases of crops; Regulates and improves the acidic environment for crop survival.

3. Because the plant ash is dry ash and does not contain a little moisture, it can be used to keep some agricultural products fresh, such as eggs at home, which can be placed in the plant ash, especially the most commonly eaten sweet potatoes, potatoes, and peppers.

4. The plant ash itself is alkaline, which can kill some pests that are afraid of alkaline, so the plant ash can be released to 10% with water sparse bends, and in the season when the pests are about to break out, the whole plant can be watered with plant ash water in advance, which can achieve the purpose of reducing insect pests.

The main component of plant ash is potassium carbonate (K2CO3), which refers to the residue of burning plants (herbaceous and woody). It is an insoluble substance. Grass ash fertilizer Because plant ash is the ash after plant burning, almost all the mineral elements contained in plants are contained in plant ash.

The gray matter of plants and trees is light and alkaline, which is easy to go away with the wind when dry and easy to go with water when wet, and it is easy to cause nitrogen volatilization loss when it comes into contact with nitrogen fertilizer.

Life: The earthen stoves of rural families burn more firewood and grass, and the grass ash produced should be collected at any time according to the above methods.

Production: Straw that cannot be transported back for use in the field is mostly burned on the spot. Attention should be paid to concentrated burning, and the ashes of plants and trees should be recovered and returned to the field.

Factories: Some power plants use straw and the like as raw materials for power generation. A large amount of plant ash produced after combustion can be returned to the field as a high-quality potassium fertilizer.

It can be made into a bagged commercial plant ash fertilizer. After adding other ingredients, it can also be made into plant ash fertilizer with a variety of uses. Some plastic products factories will also produce a large amount of plant ash when burning boilers, all of which are firewood, and the ash produced is pure white grass ash or off-white, powdery, without any impurities, and the pH value is about 12 after testing.

Storage: The gray matter of plants and trees is light and alkaline, which is easy to dig forward with the wind when dry, easy to go with water when wet, and easy to cause nitrogen volatilization loss in contact with nitrogen fertilizer. Therefore, the following methods should be taken to accumulate plant ash:

1. Storage, farmers with conditions should build a permanent plant ash warehouse, and pour the ashes into Li Chun's warehouse every day for accumulation. The ash silo should have a canopy, the ground should be high (to avoid water accumulation), hardened, and moisture-proof.

2. Bagging, if conditions permit, the plant ash should be packed in a plastic bag in time and sealed for preservation.

3. Single storage, strictly avoid mixing with other farm manure. Some farmers are accustomed to pouring plant ash into puddles and mixing it with organic manure and straw, while others put plant ash in toilets or mixing it with human manure and manure. It is very wrong to do so.

Because the plant ash is alkaline, the result of the above practice will cause the volatilization of nitrogen in organic fertilizer and reduce the fertilizer efficiency. Treating plant ash in this way will not only cause waste of fertilizer, but also cause environmental pollution. <>
