What pesticides can be mixed with plant ash? What is the reason?

Question: What pesticides can be mixed with plant ash?

Answer: Grass ash is a solid powder, which contains charcoal particles, wood residue, dust and other impurities. Grass ash is a kind of potassium fertilizer with a very high potassium content in farmhouse fertilizer, with a potassium content of 5 8%, of which more than 90% is water-soluble substance, which exists in the form of potassium carbonate in plant ash.

It also contains phosphate fertilizers, which are soluble phosphorus-containing compounds. Grass ash is an alkaline substance and cannot be mixed with acidic substances, such as ammonium nitrogen fertilizer, decomposed human and animal manure, acidic pesticides and other acidic substances.

Pesticides are generally sprayed with aqueous solution as the main method of use, and dust is rarely used. Because the use of dust will pollute the atmospheric environment, it is not environmentally friendly. Acidic pesticides include dimethoate, dimethoate, ethephon, methyl parathion, malathion, carbaryl and other acidic pesticides, which cannot be mixed with plant ash leach.

Otherwise, it will reduce the fertilizer efficiency and pesticide effect.

In short, plant ash is an alkaline substance, whether it is used in dry matter or in the form of leaching solution, it cannot be mixed with acidic pesticides and chemical fertilizers to avoid reducing the efficacy and fertilizer effect, resulting in the waste of plant ash, pesticides and fertilizers. Be careful when using it.

Thank you: Grass ash, high-quality farmhouse potash.

It's a pity that for the sake of environmental protection, no smoke is allowed now. Therefore, the farmer has no plant ash. At all, there is no need to worry about the application problem.

Grass ash, weak alkaline fertilizer.

Do not be associated with acidic and slightly acidic fertilizers.

Boric acid, which is often sprayed, is alkaline and can be sprayed with plant ash leaching solution. Potassium supplementation and boron supplementation, Bordeaux liquid, and stone sulfur mixture are alkaline, but they cannot be applied together.

Commonly used, most of them are acidic or slightly acidic, and they should not be mixed with them. Thank you!

No; Since the potassium contained in plant ash is mainly potassium carbonate, which is an alkaline fertilizer, potassium carbonate in plant ash reacts with ammonium nitrogen to produce volatile ammonia and lose nitrogen. Therefore, plant ash should not be mixed with farmhouse fertilizer and ammonium nitrogen fertilizer. If it is not suitable for mixed use with ammonium carbonate, ammonium chloride, ammonium sulfate, ammonia, etc.

In addition, although urea is a neutral organic nitrogen fertilizer, urea is hydrolyzed into ammonium carbonate or ammonium bicarbonate when applied to the soil. Therefore, plant ash is still not suitable for mixing with urea.

As for the mixing of plant ash and superphosphate. Due to the acid-base reaction between superphosphate (Ca(H2PO4)3·H2O) and potassium carbonate (K2CO3) in plant ash, the product is mainly potassium dihydrogen phosphate (KH2PO4), and the sulfuric acid partially retained in superphosphate reacts with potassium carbonate in plant ash to form potassium sulfate (K2SO4).Both potassium dihydrogen phosphate and potassium sulfate are soluble in water and easily absorbed by plants.

However, in the process of chemical reaction between superphosphate and potassium carbonate in plant ash, its carbonate and calcium ions will be transformed into calcium carbonate. Whereas, calcium carbonate is a poorly soluble compound.

Therefore, the mixing of plant ash and superphosphate should be used with the mix, otherwise it is easy to produce agglomeration and reduce the due fertilizer effect. Although, plant ash should not be mixed with livestock manure, human manure, ammonium nitrogen fertilizer, etc. However, for the soil modification of fruit trees planted in mountainous areas, organic fertilizer and plant ash can be layered and deeply applied.

In this way, even if the ammonia produced by the two fertilizers is in contact, as long as the soil is covered in time after application, the nitrogen loss caused by the escape or waving of the pants will be greatly reduced.

Rational application methods of plant ash.

1. As a base fertilizer, it can supplement the phosphorus and potassium elements required by plants, and can also improve the soil quality and make the soil loose and breathable.

5. Grass ash has medicinal value. When I was a child, due to my greed for play, I bumped and bumped everywhere, and there were inevitably a lot of small wounds on my body, but at that time, I generally didn't go to the clinic in the village, and I felt that it was a trivial matter, and the old people would use the grass and wood ashes at the bottom of the pot to put it on it, and it would be better after a while, and I thought it was amazing at that time. At that time, due to my young age, I didn't know the reason, but now I know that plant ash can reduce inflammation and is good for wounds, so now people use it as medicine.

Grass ash cannot be used with fertilizers such as ammonium sulfate, ammonium nitrate and ammonium bicarbonate. Grass ash is alkaline fertilizer, can not be mixed with ammonium sulfate and other acidic fertilizers, if they are mixed with plant ash, after the occurrence of acid and alkali neutralization, the nitrogen in the nitrogen fertilizer will disappear into ammonia.

Plant ash. It is a common item in the countryside, which family does not burn firewood and grass? In some areas, it is forbidden to burn firewood and grass, but I have not heard of it here, and in winter, it is all about burning kang with corn stalks and cutting the branches of fruit trees. The embers left over from the fire are plant ash, also known as small ash.

Most are used as fertilizers.

Wood ash contains potassium, calcium, phosphorus, magnesium, sulfur, sodium and other elements, and the amount of components contained in the embers after ignition is different from different raw materials, which is also related to the level of incineration. But in general, plant ash contains more potassium, mainly ammonium bicarbonate.

This is followed by ammonium sulfate.

Very little chlorine than potassium, all water-soluble.

of potassium; Then there is phosphorus and so on. Grass ash contains a lot of trace elements.

Therefore, it is called high-quality organic fertilizer. Because plant ash contains more potassium, it is also called high-quality potassium fertilizer. Grass ash can be used as base fertilizer, fertilization and leaf fertilizer.

Mix the plant ash with appropriate water, and after depositing it statically, take its solution too carefully, which is a water-soluble fertilizer, which can be sprayed on the leaves. Grass ash liquid plus moderate water spraying, because it contains a variety of potassium, phosphorus, calcium, magnesium and other large, medium and nutrient elements, can be digested and absorbed by crop leaves, stems and fruits, promote the growth and development of crops, make them thick, green, fruit, improve efficiency.

Most bacteria in nature prefer to grow and develop in acidic conditions, but the ash water of plants and trees is alkaline, and when sprayed on the foliage of crops, it changes the natural environment in which pathogenic bacteria survive.

It has been inhibited from growing, so it has the effect of sterilization and disinfection. For example, downy mildew, rust, etc. of crops, spraying grass and wood ash water will obtain certain control. For example, everyone here will soak 3 catties of plant ash in 6 catties of water, soak it overnight and then think about the gray water, and spray shallots with 2 buckets of water.

Small seedlings, sprayed once every 7 days, after spraying 2-3 times, the growth and development of onion seedlings is good, the production of pests and diseases is less, and the ability to resist disease damage and lodging are significantly enhanced.

Grass and tree gray water has a certain destructive effect on leaf pests such as cotton aphids and planthoppers, and the key is also due to alkaline. Like before, we used plant ash to get rid of insects, and when the dew was not dry, we sprinkled grass ash on the bean leaves to destroy the bean insects.

and other insect pests. <>

If you soak 10 catties of plant ash in 50 catties of water, soak it overnight, and spray it on the human body of raw cotton aphid or planthopper after consideration, which has excellent actual effect of insect removal, and also has the effect of applying potassium fertilizer to improve the resistance of plants to lodging.

All in all, plant ash water can supplement vitamins, is a good leaf fertilizer, and can have the effect of insecticide, sterilization and disinfection. But after all, plant ash is a alkaline fertilizer, so it cannot be mixed with acidic chemicals; In addition, the ash water contains calcium, and it is not necessary to mix it with phosphorus and potassium fertilizers containing organic matter, so as to prevent reducing the effectiveness of phosphorus and potassium fertilizers, it is best to spray alone.

It helps to fertilize crops, absorb some nutrients from plant ash, and also help prevent insect infestations; When spraying fertilizer, you must be careful not to apply more fertilizer to avoid overnutrition.

Grass ash is a common thing in the countryside, who doesn't burn firewood and grass? In some places, it is said that it is not allowed to burn firewood and grass, but I have not heard of it here, and in winter it is burned with corn stalks and pruning the branches of fruit trees. The ashes left over from the fire are plant ashes, also called small ashes, and most of them are used as fertilizer.

Grass ash contains potassium, calcium, phosphorus, magnesium, sulfur, sodium and other elements, and the amount of components contained in the ash after burning different raw materials is different, which is also related to the degree of combustion. But all in all, plant ash contains the most potassium, mainly potassium carbonate, followed by potassium sulfate, and very little chlorine than potassium, all of which are water-soluble potassium; Then there is phosphorus, etc.

Grass ash is known as a high-quality organic fertilizer because it contains a lot of nutrients. And because plant ash contains the most potassium, it is also called high-quality potassium fertilizer. Grass ash can be used as base fertilizer, top dressing and foliar fertilizer.

Mix the plant ash with an appropriate amount of water, and after static precipitation, filter its aqueous solution, which is water-soluble fertilizer, which can be sprayed on the foliar surface.

Grass ash liquid is sprayed with an appropriate amount of water, because it is rich in potassium, phosphorus, calcium, magnesium and other large, medium and trace elements, which can be absorbed by crop stems, leaves and fruits, promote the growth of crop stems and leaves, make them thick, green, good fruit quality, and improve yield.

In short, plant ash water can supplement nutrients, is a very good foliar fertilizer, and can play a role in insecticide and sterilization. But after all, plant ash is an alkaline fertilizer, so it cannot be mixed with acidic substances; In addition, the ash water contains calcium, and it should not be mixed with inorganic phosphate fertilizer, so as not to reduce the effectiveness of phosphate fertilizer, and it is best to spray it alone.

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. It is strictly avoided to mix and stack 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 method 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.

Therefore, plant ash should be applied separately, and cannot be mixed with organic farm fertilizer (human manure, manure, compost manure, 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.

In planting, can human manure and urine be mixed with plant ash? Hear what the agricultural experts have to say.

It should not be mixed with acidic fertilizers.

Can plant ash be mixed with Fubang tobacco stem yeast organic fertilizer?

Grass ash is the ash or ash left over from the burning of plants. Grass ash contains about 6% 12% potassium oxide, which is a good potassium fertilizer. In fact, plant ash not only contains potassium, but also contains more phosphorus and calcium, as well as magnesium, boron, zinc, sulfur, molybdenum, copper and other trace elements.

Therefore, plant ash is a more ideal veritable high-quality fertilizer.

If you want to give full play to the fertilizer effect of plant ash and achieve good results, you must understand its characteristics and use it scientifically and reasonably

1. Because the plant ash contains more potassium salts, especially the content of potassium carbonate, followed by potassium sulfate, and a small amount of potassium chloride, it is a physiological alkaline fertilizer. Therefore, plant ash should not be mixed with ammonium nitrogen fertilizer, nor mixed with organic fertilizers such as circle fertilizer and human manure. The best way to do this is to accumulate and use it separately so that the fertilizer efficiency can be maximized.

2. Because more than 90% of the potassium fertilizer contained in plant ash is soluble in water, plant ash is a fast-acting potassium fertilizer. Therefore, plant ash can be used as both base fertilizer and seed fertilizer, as well as top dressing. In addition, its aqueous solution can also be used as an extra-root top dressing.

3. Although plant ash can be applied in holes and strips, it is best to apply it intensively. When applied, the depth is generally 8 10 cm, and the upper edge should be covered with soil after application. The amount of plant ash per mu is generally about 30 50 kg.

In order to prevent the ashes of the grass and trees from flying, it can be sprayed with a little water when applied, or it can be mixed with an appropriate amount of wet soil before application.

Grass ash is alkaline and cannot be mixed with ammonium nitrogen fertilizer, unripened organic fertilizer, human manure and other fertilizers. It is also not suitable for mixing superphosphate for a long time for later use.

It can be mixed with potassium nitrate and potassium chloride.

Grass ash is an organic fertilizer rich in elements, because of its unique personality, it is best to store it alone, and do not mix it with other fertilizers. If you want to mix it, only potassium nitrate is not an ammonium nitrogen fertilizer, and it can be mixed with plant ash.
