Onions are in great need of timely, correctly selected dressings. A feature of this crop is a high level of responsiveness to mineral fertilizers, in fact, the onion "absorbs" all the nutrients that are introduced, depleting the soil.
How to fertilize onions to get a high yield? To begin with, the soil for the plant must be prepared in the fall. The selected area is fertilized with humus or compost, 10 kg of fertilizer are applied per square meter. If the soil is poor, then you can use mineral fertilizers. After that, the site is dug up.
Immediately before planting the onions, a spring digging is carried out, which is less deep than the first. Then nitrogen fertilizers must be applied to the site in the following proportions: 5 g per 10 liters of water.
For normal vegetation, onions really need phosphorus. Therefore, the second feeding, which is carried out after the appearance of the first full-fledged leaves, is phosphorus. 30 g of superphosphate is diluted with 10 liters of water.
Liquid organic fertilizers are also used for feeding. To do this, 1 liter of manure or manure is poured into 5 liters of water and left for 2-3 weeks, by the beginning of the fermentation process. Then the resulting infusion is diluted, six parts of water are used for one part of manure, and 1 to 20 for poultry droppings.
Fertilizers not only promote high yields, but also attract pests such as onion flies. Therefore, before fertilizing the onion, it is imperative to dust the plant with tobacco or wood ash.
During feeding, it is necessary to adhere to the recommended ratios, since an overdose can adversely affect the onion.
