Currant is one of the most common shrubs in personal plots. To some extent, it is unpretentious, but for a good harvest and growth it is picky about the nutritional value of the soil. Therefore, fertilization should be systematic, but with an eye on the characteristics of the soil. Then, like any plant, the currant will gratefully respond to the attention of the owner.
- For the main fertilizer, per 100 sq. M.:
- - rotted manure 3-4 centners;
- - superphosphate 3, 5 - 4 kg;
- - potassium salt1 - 1, 2 kg;
- - ammonium nitrate - 2 kg.
- For top dressing per 100 sq. M.:
- - ammonium nitrate 13 kg;
- - wood ash (as a substitute for potash salt) 250-300 g per bush.
The main fertilization of the soil under currants in the fall
Dig up the soil under the currant bushes. When digging, keep the shovel with the edge towards the bush to reduce damage to the roots. Dig shallow near bushes, the farther from the base of the bush, the deeper you can dig the earth.
During digging, add well-rotted manure. It is rotten, since fresh will burn the fibrous roots of the currant. Use manure at the rate of 3-4 kg per sq. Be sure to add superphosphate (30-40 g / m2) and potassium salt (10-12 g / m2). Instead of potassium salt, you can use wood ash (240-300 g / m2)
The main fertilization of the soil in the spring
Apply this fertilization only if you did not make the main soil fertilization in the fall. Dig in early spring as soon as soil allows. Prepare organic and mineral fertilizers. It is best to use slurry or bird droppings at this time of year. They must be diluted with water. The manure is diluted in a ratio of 1: 3 and mixed well. Poultry droppings are bred at the rate of 1 kg for 2 buckets of water. Use a complete mineral fertilizer, also diluting it with water at the rate of 1 kg for 5-6 buckets of water.
Dig up grooves with a depth of 10 cm on both sides of each bush, at a distance of half a meter. Add liquid fertilizers to them. Slurry will need 6 liters per bush (bird droppings - 4 liters), full mineral fertilizer - half a bucket per bush. Instead of a ready-made mineral fertilizer, you can take 20 g of ammonium nitrate, 40 g of superphosphate and 15 g of potassium salt and dilute them also in half a bucket of water. As soon as the water is absorbed, dig in the grooves and loosen the soil.
Top dressing of the soil in spring
Apply a spring top dressing if you fertilize the soil completely in the fall. Loosen the soil under the bushes. Make grooves as described in the previous step. Add 50-60 g of ammonium nitrate or 40-45 g of urea (per bush). Both can be diluted in 2.5 liters of water. Feed the currants with the same amount of ammonium nitrate per bush while the ovaries are forming.
Top dressing of the soil in summer
Do the last dressing after harvest. Feed again with ammonium nitrate or urea, but only in smaller doses - 30-40 g of nitrate or 20-30 g of urea per bush. Water the plants liberally. Use 2-3 buckets of water for each bush.
