What are the hazards of excessive use of plant ash to the soil?

Growing up in the countryside, I am particularly familiar with making fertilizer from various materials in my daily life, and after the wood and hay are burned, I can not only get ashes, but also a lot of grass and wood, which is very suitable for raising flowers. They are good fertilizers and also good fungicides. However, it should be noted that excessive use of grass wood before using grass wood can cause the soil to be alkaline, but in the southerly regions, the soil is slightly acidic, and grass wood can be used to regulate the acidity of the soil.

It's also more practical. Usually we use wood, and what is left after the fire is the wood meeting, and the one that burns with hay and various leaves is the first meeting, which have slightly different nutrients, but are generally very similar.

The charred wood material is silvery-white and contains a lot of calcium carbonate.

It is a pure natural lime compound. Chuhui also contains a lot of potassium, but not as much as Muhui, which has about 35% potassium, as well as trace elements such as magnesium and iron.

When growing vegetables in the countryside, if you are afraid of all kinds of insects in the vegetables and do not need to spray pesticides, then spraying plants and trees is a good choice. It also plays a bactericidal role, driving away pests and making plants grow better. Grass and wood contain a lot of calcium carbonate, soak grass and wood in clean water and pour water on the soil.

This solution can appropriately reduce the acidity of the soil and is a good substitute for lime. However, if the soil has already heard that plants and trees, especially plants raised in pots, long-term spraying of tap water can easily alkalize the soil, so do not use plants and trees at this time.

Let's see what plants do. Because grass and wood are the remaining ashes of plant burning, grass and wood contain a variety of minerals in the plant, but the main content includes potassium, phosphorus, calcium, iron, zinc and other trace elements. Potassium is involved in the activation of enzymes, photosynthesis, and carbohydrates during plant growth and development.

Sex ratio of proteins.

Therefore, the application of super wood in the process of flower cultivation can promote the growth of plant roots, increase the photosynthesis of plants, promote flowering, reduce leaf litter, make branches lush, and at the same time prolong the flowering period and improve the ornamental effect.

Potassium ions. The presence of plant leaves weakens the effect of plant leaves on transpiration and promotes the transport of carbohydrates, so the resistance of plants to drought and resistance to high temperature pests and diseases can also be effectively strengthened. We should know how to use plants and trees.

In general, plants and trees are placed at the bottom of the pot and used as a base fertilizer. After soaking the plants and trees for 4-6 hours, spray the asphalt suspension directly on the surface of the plants. Soak directly in an aqueous solution to water the flowers.

The main component of plant ash is K2CO3, which is a strong alkali and weak salt, the solution is alkaline, which can neutralize the acid in the soil and achieve the purpose of improving the soil. It will reduce soil fertility.

If the plant ash is used too much, it will not cause some damage to the plant, in fact, we should always remember the truth that it is too much, and the proper use of plant ash can make the flowers and plants grow more quickly, and the flowers bloom bigger, more beautiful and beautiful. At the same time, plant ash is an alkaline substance, which can play a role in killing viruses and effectively reduce the probability of pests and diseases.

However, we also need to keep in mind that plant ash is an alkaline substance, and if used in excess, the pH of the soil will change, and the growth of plants may be inhibited. After all, different plants have different requirements for the pH of the soil, and the growth of alkaline plants may be affected to a certain extent.

The main active ingredient of plant ash is potassium carbonate, which is a weak acid and strong alkali salt, and after hydrolysis, potassium ions exist completely in an ionic state, and a part of carbonate ions forms bicarbonate ions, and at the same time hydroxide is generated, and the soil forms alkaline.

By the way, any concentration of potassium carbonate solution is alkaline.

When using plant ash, you can use organic fertilizer as a base fertilizer, or you can add plant ash to the soil appropriately when preparing nutrient soil, so that the plant can fully accept nutrients, but also speed up the growth rate of the plant, and usually you can also use plant ash for the fruit tree, which can improve the drought resistance of the fruit tree.

First of all, a brief introduction to what plant ash is. Plant ash is the ash left after the burning of grass or leaves and branches, which belongs to the inorganic fertilizer of farmers, and is an easy-to-obtain potassium fertilizer with light texture and loose texture (because the organic matter is burned out when the vegetation is burned, leaving inorganic matter that cannot be burned, such as potassium, calcium, magnesium, phosphorus, iron, etc., of which the potassium content is the highest, containing 5% 15% of available potassium).

The first use of plant ash: to promote germination.

<> vegetables, flowers, seedlings and other surfaces such as sowing or seedling fields to level the soil, cover 1 2 cm with plant ash, can effectively increase the temperature of the land, promote the early germination of seeds (especially for some plants that are not easy to germinate or germinate for a long time, can germinate 7 10 days in advance), the germination rate is high, and the growth of flower seedlings will be more neat and robust.

Therefore, for friends who sow flowers in early spring, if there is no condition to provide a suitable room temperature, then you might as well use this way, which is to cover the potting soil with a layer of plant ash for insulation, so that the seeds can germinate smoothly, and the seedlings are also very robust, with good resistance and not easy to die. Mama Mei planted pepper seedlings in this way in early spring, because the weather in March and April is very unstable, with rain, snow and hail occurring from time to time. Grass ash really helped a lot.

It acts like a plastic film.

In practice, pay attention to the fact that the texture of the plant ash is very light, and you should choose to let the plant ash scatter with the wind in the morning and evening. If there is a lot of dew at night, the plant ash tends to adhere to the ground, and if the soil surface is very dry, it is recommended to spray the plant ash first.

After all, plant ash is a potassium fertilizer that does not cost money, and it can also effectively improve the acid-base balance of the soil by supplementing grass ash at the same time, and plant ash contains more potassium and phosphorus, and contains other medium and trace element fertilizers. Therefore, for sprinkling in wheat fields, it can be a good supplement of trace elements. At the same time, it can also improve the soil environment.

The second use of plant ash: to prevent wounded flow.

When we prune flowers or crops or prune the root system, we will find that some plants have a lot of sap, such as keel, tiger plum, fig, grape, etc. Under normal circumstances, it doesn't matter if a little sap is a little bit, the wound will slowly shrink and scab over, but in the humid season, the season of bacterial growth, such a wound is easy to be infected with bacteria, causing black rot (called wound flow), and even the whole plant will gradually die.

When grass and wood are used as fertilizer, they should not be mixed with organic farm fertilizer and ammonium nitrogen fertilizer. When fertilizing, it can be used as basic fertilizer, seed fertilizer, autumn fertilizer, and can also be used as seedling raising and transplanting sets. The fertilizer should not be too large, separate the seeds, and do not let the seeds burn.

The amount of graves used is generally 50 100 kilograms. Soil application is suitable for concentrated application, which can be used at the same time as the morning market and the blood market, with a depth of 8 10 cm, and the soil is covered with soil. Mix the wet soil 2 3 times before application or spray it with a little water and then use.

More than 90% of the potassium contained in super wood is soluble in water, which is a fast-acting potassium fertilizer. According to this property, ultra-wood can be used as an extra-root autumn rain, i.e. ultra-wood leachate with a concentration of 1%, which is sprayed on the foliage. Grass timber is suitable for a variety of crops, especially dilute potassium or dilute potassium goat crops such as potatoes, sweet potatoes, tobacco, grapes, sunflowers, sugar beets, etc.

Grass wood is used for potatoes, not only for soil application, but also for sweet potato tuber wounds, which can be used as fertilizer to prevent wound decay. Grass and wood can be used as a base fertilizer seed ratio or autumn ratio, and its aqueous solution can also be used as an extra-root autumn ratio. Southern grass and timber have a great use for fertilizing rice seedling fields, which can provide nutrients, increase ground temperature, prevent rotting seedlings, loosen the topsoil, seedlings and other effects.

Grass timber is the mulch on seedlings, which is ideal for growing fertilizers, which both provide nutrients and loosen the soil and raise soil temperature.

Growing crops and using bone meal in rural areas are good sources of phosphate fertilizer. Bone meal is made by processing the bones of animals. However, bone meal is insoluble in water and fertilizer is inefficient, so it is suitable as a base fertilizer (most suitable for acidic soils).

There is the problem of untreated bone meal, which contains a lot of fat, floating in the rice fields. Therefore, it is necessary to apply a spell, and a small amount of alkaline substances, such as plants and trees, can be added together to accumulate and decay, and saponification. This is also a method of disposing of the chemical fee (bone meal) with a more prominent effect of plants and trees.

Ultra wood should not be mixed with fertilizers containing amide or ammonium nitrogen. Grass and wood are rich in properties, but some of its components are products of inorganic salt combustion, such as potassium, magnesium, calcium, etc. These elements are products formed after combustion and have a certain alkalinity.

Therefore, when mixed with fertilizers containing amide nitrogen or ammonia nitrogen, amide nitrogen or ammonia nitrogen will undergo a substitution reaction in an alkaline environment, resulting in nitrogen fertilizer waste. In particular, fertilizers such as urea, ammonium sulfate, ammonium carbonate, etc.

The ultra-wood composition is quite complex. The ash elements contained in the plant body are all in phosphorus, potassium, calcium, magnesium, sulfur and other super wood. It is rich in potassium, phosphorus and calcium, and the general potassium content is 5% to 10%.

No matter what plant ash, the potassium contained in it is soluble, fast-acting, and can be directly absorbed and utilized by crops. Plants and trees are alkaline fertilizers and cannot be mixed with ammonium sulfate and ammonium nitrate. Ammonium sulfate, ammonium nitrate, and ammonium bicarbonate are all ammonium nitrogen fertilizers, and when mixed with plant ash, the nitrogen in the nitrogen fertilizer will turn into ammonia.

When plants and trees are used with acidic fertilizers, care must be taken not to mix them together.

Grass ash is easily mixed with ammonium nitrogen fertilizer, nitrate nitrogen fertilizer and rotten and ripe human and animal manure and urine, which will cause nitrogen volatilization loss, which should be avoided. If acidic fertilizers and acidic organic fertilizers, such as ammonium sulfate, ammonium chloride, superphosphate, human urine manure, livestock manure and other acidic fertilizers, chemical reactions will occur to make the fertilizer ineffective.

First, grass and gray fertilizers are alkaline fertilizers, which must be avoided mixed with acid fertilizers, the main component of grass ash is potassium carbonate, but at the same time it contains all plant mineral elements, only potassium elements have the most content, more than 90 can be water. As a typical alkaline fertilizer, grass ash cannot be stored or mixed with acid fertilizers. Second, the amount of grass ash is not suitable for alkaline soil, because grass ash itself is alkaline, if alkaline soil is given, it will increase the amount of alkalinity of soil to a certain extent, resulting in a more biased bias of soil, which is not conducive to soil improvement.

Therefore, we use grass as a companion to acidic or neutral soils, on the one hand, we can achieve soil improvement effects. On the other hand, the effect of grass ash can be achieved. When using grass ash, it is better to cover the soil so that the effect can be guaranteed.

Or after administration, proper water allows nutrients such as grass to enter the soil road, accelerating the crop and accelerating the crop's uptake of grass.

Grass ash should not be mixed with human feces and livestock feces. In rural areas, it is customary for farmers to pour grass ash into pits or manure, which is wrong. Animal manure, human manure, etc. is a kind of delayed acidic nitrogen fertilizer, the alkaline plant ash is poured into the acidic livestock manure, human manure, acid and alkali neutralization, will reduce the fertilizer efficiency.

Plant ash is the residue of the plant after it has been fully burned, containing various elements in the plant, and the composition is relatively complex. Since it contains potassium carbonate, many people tend to think of it as a potash fertilizer. In fact, plant ash contains the most calcium, up to about 30%, potassium about 5% to 10%, phosphorus 1% to 4%, nitrogen.

The form of presence of the main components, especially potassium, is also different at different combustion temperatures of plant ash.

<> industrial plant ash (plant ash produced by industrial boilers such as power plants) is formed by the burning of plants at high temperatures. Potassium and silicic acid form potassium silicate (K2SiO3), the solubility is low, potassium silicate is gray, so the appearance of industrial wood ash is darker, dark gray or black gray, and the fertilizer effect is not as good as that of conventional burning wood ash.

Plant ash burned at low temperature (conventional combustion) is generally dark black, with potassium carbonate predominantly potassium carbonate, followed by potassium sulfate, and potassium chloride is the least. It is about 90% soluble in water, which is particularly effective and has high fertility.

Plant ash is an available potassium fertilizer that can be used as a base or surface fertilizer. It is often used as a base fertilizer in actual production.

The aqueous solution of potassium carbonate (K2CO3) is alkaline, so plant ash is an alkaline fertilizer, which has the ability to safely regulate acid, and the effect is more obvious under acidic soil conditions.

Because plant ash contains a certain amount of carbon and the color is dark black, it has a strong ability to absorb heat and heat up quickly, and its use in spring is conducive to increasing ground temperature. Plant ash should not be mixed with ammonium nitrogen fertilizers, human excreta and urine to avoid nitrogen loss. It is generally not recommended to mix it with cooked soil 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.
