HOW TO FEED ONIONS ON THE HEAD: ONION ORGANIC AND MINERAL FERTILIZERS

Onion is one of the most favorite gardeners crops. At any time of the year, it will give the dishes a distinctive spicy taste, saturate them with vitamins and trace elements. But in order to ensure a good harvest, the summer resident must know how to feed the onions.

Did you know? The most common food in the world - namely onions.

Onion fertilizer on fertilizer

It was revealed that for growing from 1 hectare 300 centners of onion, the vegetable consumes from the soil:

75 kg of potassium;
81 kg of nitrogen;
48 kg of lime;
39 kg of phosphoric acid.

When applying mineral fertilizers culture consumes:

25-30% phosphorus;
45-50% potassium;
100% nitrogen.

This information should be considered when feeding onions on a turnip.

You also need to know that phosphorus is consumed evenly throughout the maturation period, nitrogen - mainly in the first growing season, and potassium - in the second. The question of how to fertilize onions is decided on the basis of the type of fertilizer, soil conditions, agricultural cultivation, etc.

It has been studied that phosphate and potash fertilizers significantly accelerate the ripening of vegetables, the bulbs become dense and large, and are well stored. At the same time, if fresh manure is applied simultaneously with the entire rate of mineral fertilizers, this will reduce the crop yield. The effectiveness of feeding onions per head also depends on the amount of heat and light.

for the third time, all attention is focused on the formation and maximum growth of the bulb (mineral fertilizers with a predominance of phosphorus).

First feeding

Experts advise two weeks after planting a vegetable diluted in 10 liters of water 40 g of superphosphate, 30 g of saltpeter, 20 g of potassium chloride. This liquid is introduced into the soil under a vegetable.

You can also use the following solution: 2 tbsp. l spoons of the drug "Vegeta" and 1 tbsp. l urea poured into a bucket of water. The mixture is also watered garden bed. One bucket of nutrient solution is spent on 5 square meters. m of soil. The best option organic fertilizer will be a solution of manure. One glass of manure is taken for 10 liters of water.

Second feeding

At the second stage, it is decided how to feed the onions so that it is large.

This feeding is carried out 30 days after planting the crop and 15-16 days after the first application of fertilizers. This time, 60 grams of superphosphate, 30 grams of sodium chloride, and 30 grams of saltpeter are added to 10 liters of water. This mixture can be replaced with the solution of the drug "Agricol-2". In a bucket of water pour 1 cup of the substance. On 2 square. a meter of land 10 liters of nutrient will be enough. For feeding onions in the spring on the head and use organic matter. The best option would be cooking herbal slurry. For this, any weeds are placed for three days in water and under a press. A glass of such liquid is enough for a bucket of water.

Third dressing

Onion feeding in spring is completed when the bulb grows up to 4 cm in diameter. For every 5 square meters. m of soil should be added 30 g of potassium chloride, 60 g of superphosphate dissolved in a bucket of water.

This solution can be replaced with "Effecton-O" and superphosphate. In 10 liters of water add 1 tbsp. l superphosphate and 2 tbsp. l substances. Feeding onions with ash will saturate the culture with the necessary organic substances. To do this, 250 g of ash is poured with boiling water (10 l) and allowed to infuse for 3-4 days.

Important! When applying fertilizers ensure that they do not fall on the foliage of the vegetable.

How to get a rich harvest of onions, organic dressing

Often gardeners wonder if onions like manure and other organic fertilizers (compost, chicken dung, etc.)?

Organic compounds improve the soil structure under the bow, enrich it with nutrients. As a result, the earth is better saturated with oxygen and air. In addition, the introduction of organic matter contributes to a better absorption of the culture of mineral compounds. However, when they are made according to the scheme described above you need to consider that:

it is not recommended to apply fresh, undiluted manure, as this can provoke onion diseases and slow down the formation of heads;
together with low-quality organic matter, weed seeds can get into the garden, which will have to be disposed of later;
When applying too large a dose of organic fertilizer, all the forces of the plant will be directed to the growth of abundant greenery, so the bulbs may not mature.

Onion fertilization rules with mineral compounds

When using mineral fertilizers for feeding onions should be remembered:

it is strictly forbidden to dilute liquid fertilizers in the dishes used for human or animal consumption of food;
do not increase the maximum dose recommended by the manufacturer;
if the mineral composition is on the green feathers of the onion, they must be rinsed with water from a hose;
before making a liquid with a mineral composition, it is desirable to slightly moisten the soil under the plants;
if one of the main elements (phosphorus, nitrogen, potassium) is lacking, fertilizers must be applied along with it, otherwise the other components simply will not work;
for sandy soils, the amount of dressings should be increased, but the concentration of the solution should be reduced. If clay prevails in the earth, it is advisable to slightly increase the dose;
with simultaneous application of mineral and organic fertilizers, the amount of the first must be reduced by 1/3.

Did you know? When perekormke mineral fertilizers in the bulbs of plants, nitrates can accumulate.

How to feed onions mixed fertilizers

Onion fertilizer may contain both mineral and organic substances at planting. In this case, feeding is carried out as follows:

the first is to add water (10 liters) with the addition of urea (1 tbsp. l.) and slurry (250 ml);
the second is preparing a mixture of 2 tbsp. l nitrophosphate and 10 liters of water;
the third one involves adding an aqueous solution to the soil: add 1 g of potassium salt to 1 bucket and 20 g of superphosphate.

Features onion feeding
