What kind of fertilizer is plant ash, and what fertilizer is used instead of plant ash?

Grass ash is an alkaline fertilizer and cannot be used or stored with acidic fertilizers, pesticides, ammonium nitrogen fertilizers, calcium phosphate, etc. , otherwise it will neutralize the fertilizer efficiency and reduce the fertilizer efficiency.

Grass ash is a fast-acting fertilizer, which cannot be used together with after-effect farmhouse urine fertilizer, otherwise it will cause fertilizer volatilization and reduce the effect of fertilizer use.

Grass ash should not be mixed with superphosphate, which will reduce the effectiveness of phosphorus. Grass ash is a kind of ash fertilizer made from firewood, which is a kind of thermal fast-acting fertilizer with a loose texture. The main ingredient is potassium carbonate (K2CO3).

Fertilizer in plant ash Since plant ash is the ash after the plant is burned, almost all the mineral elements contained in the plant are in the plant ash. Among them, potassium is the most abundant element, generally containing 6-12% potassium, of which more than 90% is water-soluble, in the form of carbonate.

<> plant ash is a kind of inorganic farmhouse fertilizer with wide range, low cost, complete nutrients and obvious fertilizer efficiency. Grass ash is the ash after the plant burns, the main component is potassium carbonate, the mineral elements contained in the plant, almost all contained in the plant ash, the most abundant is potassium, generally containing 6%-12% potassium, followed by phosphorus, generally containing, but also contains calcium, magnesium, silicon, sulfur and iron, manganese, copper and other trace nutrients.

1. What kind of fertilizer is plant ash?

1. The residue of plants (herbaceous and woody plants) after burning is called plant ash. The fertilizer is due to the ash of plants after burning, and the main component is potassium carbonate (K2CO3).

2. Grass ash fertilizer is because plant ash is the ash after plant burning, so it is the mineral element contained in all plants, almost all of which are contained in plant ash, the most abundant of which is potassium, generally containing 6-12% potassium, of which more than 90% is water-soluble, in the form of carbonate, followed by phosphorus, generally containing, calcium, magnesium, silicon, sulfur and iron, manganese, copper, zinc, boron, molybdenum and other trace nutrients.

3. The ash and nutrient content of different plants are different, the potassium content of sunflower straw is the highest, and the fertilizer effect will be better than that of chemical potassium fertilizer when applying plant ash at the same potassium amount, so it is an inorganic farm fertilizer with low cost, wide range, obvious fertilizer efficiency and complete nutrients, light and alkaline, easy to go with the wind when dry, easy to go with water when wet, and easy to cause nitrogen volatilization loss in contact with nitrogen fertilizer.

2. How to store plant ash

1. Warehouse storage. Farmers with certain conditions can build a permanent ash silo of plants and trees, pour ash into the silo every day, so as to facilitate accumulation, the ash silo should be equipped with a canopy, the ground should be high to avoid water accumulation, and it should be moisture-proof.

2. Bagging. If conditions permit, the plant ash can 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 the puddle and mixing with organic fertilizer, straw, etc., and some put plant ash pad toilet or mixed with manure, human manure and urine, this practice is wrong, plant ash is alkaline, mixed with other farm manure will cause the volatilization of nitrogen in organic fertilizer, reduce fertilizer efficiency.

3. Precautions for the use of plant ash fertilizer

1. Grass ash is an alkaline fertilizer, which cannot be mixed with acid fertilizer, ammonia nitrogen fertilizer, calcium phosphate, etc.

2. Grass ash is a rapid fertilizer, which cannot be poured into delayed farm fertilizer and mixed together.

3. Grass ash cannot be mixed with superphosphate.

Humic acid compound fertilizer.

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 varies from plant to plant, with the highest potassium content in sunflower straw (see table below for details).

When the same amount of potassium was applied to plant ash, the fertilizer efficiency was better than that of chemical potassium fertilizer. Therefore, it is a kind of inorganic farm fertilizer with wide range, low cost, complete nutrients and obvious fertilizer efficiency.

Grass 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.

The main element in plant ash is potassium, and the plant ash is potassium oxide just burned. Because potassium hydroxide is generated after adding water, it is very alkaline and easy to hurt the roots. It is best to let it take a period of time for potassium oxide to convert into potassium carbonate and weaken alkalinity.

There is no plant ash to use a lot of potassium fertilizer, potassium chloride (tobacco leaves, potatoes, sweet potatoes, sugar beets, citrus, tea fields are not suitable for use), potassium sulfate, and now there are compound potassium chloride magnesium, potassium magnesium sulfate.

Grass ash corresponds to potassium fertilizer in fertilizer, so potassium fertilizer can be used instead of plant ash.

Don't throw away the plant ash, it is still a good fertilizer for raising flowers, throw it in the pot, and the flowers will easily burst the pot.

Grass ash is a loose heat-based fast-acting fertilizer.

Grass ash fertilizer because plant ash is the ash after plant burning, so all the mineral elements contained in plants, almost all plant ash contains, is a loose texture of thermal fast-acting fertilizer. 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 iron, manganese, copper, zinc, boron, molybdenum and other micro-nutrients.

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. Therefore, it is a kind of inorganic farm fertilizer that is extensive, low-cost, complete in nutrients and obvious in fertilizer efficiency.

Uses of plant ash

1. Accelerate rooting.

In seedling transplanting, using plant ash with organic fertilizer as base fertilizer, or preparing nutrient soil mixed with 5 -20 plant ash, can not only increase effective nutrients, promote root wound healing, and improve the survival rate of seedling transplanting.

2. Prevent falling leaves.

Spraying 8 to 15 plant ash leaching solution as topdressing outside the root can improve the photosynthetic efficiency of leaves, prolong the lifespan, prevent early defoliation, and enhance the photoconservation effect.

3. Inhibit pests and diseases.

The nursery sprinkles 30-50 kg of plant ash per mu, which can kill underground pests and bacteria, protect seeds, roots and stems, reduce the damage of pests and diseases, and prevent blight and anthracnose.

4. Increase ground temperature.

In winter, the base of the pepper tree is covered with a layer of plant ash to increase the ground temperature and prevent the roots from being damaged by frost.

Grass ash is an inorganic farm fertilizer.

Grass ash is a widespread, complete nutrients, low cost inorganic farm fertilizer, light texture and alkaline, because plant ash is the residue of herbaceous and woody plants after combustion, so its nutrient content is different, such as sunflower straw potassium content is the highest, and the use effect is significantly better than chemical potassium fertilizer.

You can pack the plant ash and put it in the rain shelter, and the ground of the rain shelter should be high to avoid water wetting the plant ash, or the plant ash can be packed in a plastic bag, and then sealed and preserved, and the plant ash should be stored separately, because it is alkaline, and the stacking with other farm manure will reduce the fertilizer efficiency.

When applying plant ash to plants, it should be applied separately, and should not be mixed with organic farm fertilizer, ammonium nitrogen fertilizer and phosphate fertilizer, so as not to lose nitrogen and affect the fertilization effect of plant ash.

The role of plant ash

The potassium in plant ash can promote the metabolism and transportation of nutrients in vegetables, enhance the ability to resist diseases and natural disasters, and make plants taller and stronger. If the potassium in the soil cannot meet the needs of vegetables, the vegetable plants will be weak and prone to lodging problems.

Grass ash has a great effect and a wide range of applications, and can be used for all kinds of vegetables, but it is more suitable for potassium-loving vegetables, such as sunflowers, sugar beets, potatoes, etc. When potato grass ash is applied, it can not only improve the soil and improve soil fertility, but also play a role in preventing potato rot.
