Ash as a fertilizer, and, very valuable, has long been recognized. Many generations of gardeners use it to improve soil fertility. Since wood ash is obtained from plant material, it contains most of the essential nutrients needed for plant growth. What is its use? Is it safe to use in the garden? Yes and no! Ash is a good source of potassium, phosphorus, some trace elements. It depends on the type of wood burned.
- Composition of ash wood
- Ash solution or infusion of wood ash - how to prepare
- the soil is deficient in potassium, then ash can fix it. And if the soil in your area is very acidic( pH less than 5.5), then it can improve the acidic composition of the soil. But if the soil in your area is neutral or alkaline, then applying ash as fertilizer can raise the pH so high that your plants lose their ability to get nutrients from the soil. ↑ to content ↑
Composition of wood ash
When firewood burns, nitrogen and sulfur go into the air in the form of gases, and calcium, potassium, and magnesium, various trace elements remain. Carbonates, oxides, remaining after burning wood, when introduced into the soil neutralize its acidity.
The value of fertilizer from burned trees depends on the type of wood you burn. As a rule, ash from deciduous trees contains a higher percentage of nutrients than ash from coniferous trees.
In any case, wood ash is the alkaline complex fertilizer. Its main advantage is a high content of calcium, potassium, magnesium, sodium, phosphorus in a form accessible to plants.
Burned wood does not contain nitrogen, which volatilizes when burned. However, this is not a reason to bring nitrogen fertilizers with it. The benefits in this case will not be, as this will lead to the formation and release of ammonia, large doses of which are dangerous to plants.
The introduction of ash helps to reduce the acidity of the soil. It is not recommended to deposit it on soils with acidity indicators( pH) of 7 or more, as this will contribute to an even greater increase in the alkalinity of the soil. It is scattered under the digging of the soil or in the grooves, the wells during planting. The maximum consumption rate for soil digging should not exceed 1 cup per square meter.m. In this case, its action will be observed for 2 - 4 years after application.↑ to content ↑
Ash solution or infusion of wood ash - how to prepare
It is possible to use the so-called ash solution or ash extract for fertilizing plants. It is prepared as follows: 1 cup of wood ash( 100-150 g) is poured with a bucket of water, insist( I leave it overnight).Garden plants are watered with this solution. Before watering the infusion is stirred. Insoluble ash particles should be evenly distributed throughout the mixture.содерж to content ↑
Wood ash - use in the garden where it is possible and where it cannot be
The burned wood can be successfully used in compost heaps to help create the best conditions for microorganisms that process organic matter. Sprinkle ash on each layer of compost to enrich the latter with nutrients.
With reasonable use, it can be used to control various pests, such as slugs or snails, as it draws water from invertebrate organs. Sprinkle ashes around your plants to scare away creeping pests. But as soon as the ashes become wet, it loses its deterrent properties. Its continuous use for these purposes can increase the soil pH much, and this is harmful for plants.
Wood ash does not contain chlorine, so it can be applied for grapes, citrus fruits, strawberries, potatoes, raspberries, currants, since these crops do not tolerate chlorine. In addition, such a fertilizer protects, for example, cabbage from diseases of the keel( a disease caused by a fungus parasitizing on the roots) and a black leg.
Do not use wood ash around plants such as rhododendron, blueberries - they love acidic soil, and it reduces the acidity of the soil, which will have a depressing effect on these plants.
Potato responds well to its use in cultivation - potato crispiness increases by 1-1.5%, but still use it carefully when planting potatoes, as it contributes to the development of such a dangerous disease of tubers, such as rhizoctoniosis or scab.
Do not use wood ash to fertilize seedlings before the appearance of the third true leaf, as it contains too many salts harmful to weak plants. When planting seedlings of tomatoes, peppers, eggplants, you can add 1 tablespoon of zolka to the hole, but be sure to mix it with the earth, and also sprinkle it on top of the soil so that the roots of the seedlings do not touch it, otherwise they will get burned - the plant will hurt, take a long time to take rootin a new place.
Do not use wood ash to repel pests on radish, radish or turnips - you may be scared off by pests, but you will not wait for the crop of radish and the like - they will go "arrow", that is, the roots will stop growing, they will harden, they will become stiff.flower arrow.
Dry wood ash during storage does not lose its beneficial properties over the years. But when wetting, it loses almost all potassium. The percentage of potassium in the ashes depends on the breed and age of the burnt tree. The younger it is, the more it contains potassium.
In comparison with phosphorus potassium, ash contains little, but this phosphorus is used by plants better than from superphosphate.содерж to content ↑
Walnut ash as a fertilizer
Some summer residents are afraid to apply walnut wood ash to the soil. Their fears are most likely based on the delusion that the plants of the nut family( walnut, manchurian, gray and black) contain the chemical juglon( nuqing) belonging to the class of naphthoquinones. This substance has an adverse effect on plants growing next to the nut.
Their concerns are unfounded. In the walnut plant, the juglon is in green peel, leaves, roots, and also the bark. When fully burned, juglone, as an organic substance consisting of carbon, hydrogen, oxygen, completely decomposes, disappears. Ash from walnut wood, as well as from other woody crops, contains potassium( 15-20%), calcium( 6-9%), phosphorus( 5%), small amounts of magnesium, iron, sulfur, zinc. In addition, it includes many other trace elements needed by vegetable crops.
Ash walnut shells can be used as a cosmetic tool, for example, to remove unwanted hair. The following recipe is recommended: shells of nuts are burned, the ashes are diluted with water. On one teaspoon of gold take 0.5 liters of water. The resulting composition is used to lubricate the skin with unwanted hair.содерж to content ↑
What other ashes can be used as fertilizer
In the garden can be used as fertilizer ash from the burning of sunflower husk, rice husk.
When burning sunflower husk, it is formed in the amount of 0.5-1.0% of the total volume. It is very rich in potassium, can be used as a valuable potash fertilizer. Ashes from sunflower husk, as well as from buckwheat straw, are leaders in the content of potassium dioxide( K2O) in comparison with wood or from other plants. You should know that when burning sunflower husk, the nitrogen from it evaporates into the atmosphere. Therefore, ash, unlike husk itself, does not enrich the soil with nitrogen, as well as woody.
In addition to sunflower husk, in areas of the Krasnodar Territory, where rice is cultivated, a considerable amount of rice husk is obtained. It is estimated that about 200 kg of rice husk is used for each ton of rice crumbled. This is a very valuable raw material. Rice husk ash contains almost all the nutritional macro-and microelements - potassium, calcium, phosphorus, magnesium, sulfur, manganese, molybdenum, zinc, boron, cobalt, etc. However, when it is burned, such elements as oxygen, carbon, hydrogen and nitrogen evaporatein atmosphere.
Can hay or straw be used as a fertilizer? To be honest, the straw from the cereal is not so much contains nutrients. Moreover, it is very much required for feeding plants. I do not think that you have her whole ricks. Of course, you can use it for all garden crops. But remember, it is considered the best because of oats, rye and rice.
Do not use ashes on your site, which is obtained from burning garbage, cardboard, coal or chipboard. These substances contain trace elements that are harmful to many plants when used in excessive amounts. For example, the glue used in the manufacture of cardboard boxes or particle boards contains boron - a toxic element for many plant species.
When you work with wood ash, you should take some precautions. Wear gloves and goggles, and if it is shallow and windy, be sure to wear a respirator.
What else can I add? Wood ash as a fertilizer is a valuable assistant to the gardener and gardener. I think we figured out when, where and how best to use it.
