Onions have long been considered an unpretentious culture, but even it needs various feeding. It would be ideal to take care of future onion beds in the fall and add cow dung or bird droppings, compost or humus to the soil in advance. But if this did not work out, then fertilizers with minerals or on the basis of organic matter, as well as mixed feeding, will come to the rescue. And this will already be in the onion growing season.
Top dressing for onions is applied two or three times throughout the season. The first fertilizer must be nitrogen-containing. It is applied approximately 2 weeks after planting. Nitrogen stimulates the growth of green mass. After another 2-3 weeks, a second top dressing is introduced, which includes not only nitrogen, but also potassium, phosphorus.
On fertile soils, these two dressings will be enough, but for depleted land, during the formation of the bulb, a third dressing (potassium-phosphorus) will be required, only this time without nitrogen.
Each recipe is based on ten liters of water.
Fertilizers are applied during watering, but only after sunset or in cloudy weather. On a sunny day, fertilizers can kill vegetable plants. The liquid dressing should be applied directly to the bulb and not to the greens. On the next day, it is advisable to wash off fertilizer residues with plain water.
SUPER MEANS FOR FEEDING AND PROTECTING ONION FROM ONION FLY !!!
Bulbs are a well-known type of this vegetable. They give a high yield, are distinguished by their taste, a good ability to preserve for a long period. Rarely does a vegetable compete with such popularity. Grown without the use of mineral fertilizers, onions are distinguished by their taste. Today you will be presented with onion feeding: mineral and organic fertilizers for onions.
12-15 days after planting, when seedlings appear, it is necessary to create conditions for the rapid growth of green feathers, that is, the first feeding should be rich in nitrogen.
In humid years, nitrogen fertilizers can be omitted on humus-fertilized soils, otherwise the leaf will grow strongly, delaying the formation of bulbs. And in general, it is worth paying attention to the condition and color of the pen. If the seedlings are strong, bright green, then there is enough nitrogen in the soil.
As a top dressing for onions, you can use mineral or organic fertilizers. And you can use both of them in combination.
15-20 days after the first feeding, the second is carried out, reducing the proportion of nitrogen fertilizers and increasing the content of potash and phosphorus.
For the third time, onions are rarely fed. Only if it grows on poor soils and looks unimportant: the feathers turn yellow, the head does not form. It is during the period of the initial formation of the head that onions are fed for the third time. At this stage of development, nitrogen is no longer necessary for plants, therefore fertilizers with a high content of potassium and phosphorus are used.
Nitrogen is the main component of feeding onion feathers. When the crop has just emerged, it is fed with urea or ammonium nitrate (30 g / m²). The preparations are scattered on the beds, after which watering is carried out. If the second agent is used dry, then after 10 days use 1 of the compositions:
The first composition is used in liquid form, the second in dry form.
It is advisable to fertilize the soil with organic matter before or after planting onions with an interval of 2 weeks.
Many gardeners, including those with experience, prefer to make organic fertilizing. Often such funds are at hand and do not need to be purchased additionally, which is an excellent savings. One more and, perhaps, the main advantage of organic fertilizers is environmental friendliness and safety for humans and plants.
Poultry manure is considered one of the most valuable fertilizers. It contains many micro and macro elements. Fertilization with droppings accelerates the growth of green mass. To prepare the solution, take 1/2 liter of droppings and dilute with 10 liters of water. Top dressing is applied directly under the roots.
Manure is also often used for feeding. Use only well-rotted manure. It is evenly scattered over the site and well dug up.
Spring feeding onions and garlic involves preparing a mullein solution. For 1 part of the mullein, take 7 parts of water. Watering is carried out.
Contains potassium. For ash feeding onions, take 200 grams of dry matter and fill it with well-settled water at room temperature. One bucket is enough.
For digging the soil, they also take 400 grams of ash per 1 m2 and apply it directly to the ground. This will protect the crops from root decay.
No more than three dressings are made per season.
Home garden owners, trying to use as little chemistry as possible, often use folk remedies that are no less effective than mineral supplements.
Ordinary table salt can be used with benefit in the beds. Sodium chloride acts as a growth stimulant, activating the absorption of nutrients by plants. In addition, salt is a reliable remedy against infections and parasites. Watering with saline solution (200 g 10 l) will help to cure feathers from yellowing as a result of onion fly attacks, from powdery mildew, and save from rot. The liquid is applied not under the root, but along the grooves 8 cm from the roots, carefully, trying not to spill it on the leaves. The first feeding is carried out at a plant height of 10 cm, the second - after 2 weeks. Before and after applying the solution, the beds should be spilled with clean water. The concentration of the saline solution should not be exceeded and after harvesting the onions, it is imperative to apply a larger amount of organic fertilizer.
Table salt promotes better absorption of nutrients by plants
An effective vegetable feed that improves their development is baker's yeast. The basis of yeast biomass is formed by fungi, which are rich in proteins, amino acids, macro- and microelements. The yeast introduced to the garden, thanks to fungi, activates the activity of microorganisms, creating a favorable environment for them. As a result, organic matter is processed faster, releasing nitrogen and potassium into the soil, which are so necessary for plants.
Both dry and fresh yeast are used to prepare the nutrient solution.
The activity of yeast fungi is manifested only in a warm environment, at a temperature of at least +20 0 C. Therefore, the use of a yeast solution is effective only in well-heated soil; in cold soil, yeast fungi quickly die.
The first feeding with yeast is carried out with the establishment of warm weather, at the end of May, one month after planting the onions. Yeast can be used no more than 3 times per season. And since calcium and potassium are absorbed during fermentation, it is recommended to add ash (200 g / m 2) to the solution to replenish the missing elements.
You can apply yeast feeding throughout the entire growth period.
Prepare top dressing from fresh or dry yeast. For 10 part of fresh yeast, take 5 parts of warm water. Withstand 1 hour, add 50 l of water and the resulting liquid is poured into the root. Dry yeast (10 g) is dissolved in 10 liters of warm water, 60 g of sugar, 200 g of ash are added and left in a warm place for 2 hours. The yeast starter culture is diluted with water (50 l) and used for watering vegetable beds.
Experienced summer residents use ammonia to saturate plants with nitrogen. A week after the emergence of shoots, 2-3 sprays are carried out with an interval of 7 days with an ammonia solution (50 ml 10 l of water).
Ammonium is used to saturate growing onions with nitrogen.
When signs of nitrogen starvation appear - premature yellowing of feathers - use daily watering with ammonia (1 tbsp. L. 25% solution per 1 l of water). The resulting solution is applied to the root in the morning or evening hours. When the color of the greens becomes deep green, fertilizing watering with such a composition is stopped.
After dressing with ammonia, onions acquire a bright green color.
Comfrey infusion is prepared for spring feeding. Green fertilizer can only be used at the beginning of the growing season, as it contains a lot of nitrogen, a large amount of which in a later period of development can lead to excessive feather growth and the formation of small bulbs. Comfrey also surpasses manure in the presence of potassium and contains almost the same amount of phosphorus. To prepare the infusion, 1 kg of chopped grass is poured into 10 liters of water and left for 7 days. The filtered liquid is diluted with water (1: 9) and used for irrigation.
The rich content of macro- and microelements has made comfrey a popular plant among gardeners.
All feeding should be stopped 3 weeks before harvesting the turnip. Otherwise, the ripening of the onion will be delayed and its safety will worsen.
I use eggshells as a natural fertilizer for onions. The shell of the egg is 95% calcium carbonate, which improves the growth of the aboveground parts of plants. In addition, it also contains iron, copper, phosphorus, potassium and other useful elements necessary for the formation of a high-quality crop. I add the shells crushed to a powdery state to the holes when planting onions (30 g / m 2), when forming a turnip, I water it with a fertilizing infusion (I pour 3 liters of hot water into ground raw materials from 5 eggs and after a week of infusion dilute with water 1: 3). Eggshells not only enrich the soil with nutrients, but also reduce acidity.
Eggshells contain a lot of calcium, as well as iron, phosphorus, potassium and other substances necessary for growing onions
Hydrogen peroxide has been used in crop production for many years. It has a fungicidal effect, aerates the soil, strengthens the root system of plants and helps the development of the aerial part.
Hydrogen peroxide oxygenates the soil and improves water quality when watering vegetables
Gardeners use peroxide to soak seeds, improve water quality during irrigation, and for fertilizing. With the weekly introduction of a solution of hydrogen peroxide (2 tbsp. L. 3% peroxide 1 l of water) pathogenic bacteria are suppressed into the soil, beneficial microorganisms are activated, which contributes to a better assimilation of micro- and macroelements. Onions fed with such a solution grow with a strong root system, juicy green feathers and large heads.
Timely feeding guarantees large onion turnips
Onions are an unpretentious crop, but in order to get a good harvest, they must be provided with the necessary nutrients. Top dressing of a vegetable should begin already at the stage of preparing the soil for onion planting. And in the future, at all stages of the growing season, plants should receive nitrogen, phosphorus, calcium and other components. For feeding, you can use mineral and organic substances, folk remedies. The main thing is to comply with the rate of fertilization and adjust the fertilizer composition taking into account the phases of development and state of the plants.
Currently, gardeners widely use a variety of folk remedies for feeding vegetable crops. Some of them are more growth stimulants than fertilizers, but they all have a beneficial effect on the development of plants, if used within reasonable limits.
Hydrogen peroxide has long been used by aquarium hobbyists to remove unwanted microorganisms from them.
The fact is that an aqueous solution of hydrogen peroxide in its composition resembles melt water, known for its regenerating properties. It contains atomic oxygen, capable of killing all harmful bacteria and saturating the soil with oxygen.
For watering and spraying onions and garlic, use the following solution: add two tablespoons of 3% hydrogen peroxide to one liter of water. Garlic winter seedlings can be watered with this composition at the earliest stage of development. Older plants can be sprayed with the same formula, which will significantly accelerate the growth and development of garlic and onions.
Yeast has such a rich composition that this fact could not fail to interest gardeners. In general, they have rather a stimulating effect on the development of plants. So, with the help of yeast, you can enhance root formation, increase plant resistance to diseases, accelerate the growth of vegetative mass. If we talk about the action of yeast as a fertilizer, then they more affect the activity of soil bacteria, activating it. And those, in turn, begin to actively process organic substances, transforming them into a form convenient for plants.
To prepare yeast fertilizer, you need to take 0.5 kg of fresh yeast and dissolve in a small amount of warm water. Then in a bucket of water you need to stir 0.5 kg of bread crumb and 0.5 kg of any herb. Finally, add diluted warm yeast. The resulting liquid must be infused for about two days. You can water plants with it in the usual way under the root.
Since it is potassium that is a vital element for these plants.
Ammonia is a 10% aqueous solution of ammonia, so it is natural to use it as the main nitrogen-containing fertilizer. This concentration is low enough that it does not cause root burns when watering, on the other hand, it would be an excellent protection against onion flies and other pests. Often, it is because of the invasion of pests that the leaves of garlic and onions turn yellow before they have time to grow.
Usually, onion plantings are watered with a solution of ammonia for prophylaxis when the first true leaves appear. For these purposes, two tablespoons are diluted in 10 liters of water. This amount is enough for the strait of two square meters of onion plantings. Then the ridges are watered with twice as much water. This is necessary so that the ammonia solution gets directly to its intended purpose - into the deep layers of the soil.
At the same concentration, ammonia solution can be used for foliar treatment of both crops in early spring. Additional protection from pests and the first feeding will be made.
