Good quality soil with a sufficient amount of nutrients is the key to the normal development and high productivity of any horticultural and horticultural crop. Therefore, correctly selected and timely applied fertilizers for currants is one of the essential conditions for obtaining a rich harvest.
The greatest amount of nutrients for this culture is required during the period of active growth of young shoots, leaves and ripening of fruits, that is, in spring and summer. Fertilizers for currants (in general, both mineral and organic are suitable, but it is better to give preference first) are applied from all sides of the bush, evenly, so that the radius of the fertilized soil slightly exceeds the radius of the crown. In this case, feeding should be carried out in accordance with the phases of plant development.
Nitrogen fertilizers, for example, ammonium nitrate, are best applied as top dressing in the spring, and phosphorus and potash fertilizers - in the fall, before digging. The norm of nitrogen, potash and phosphorus fertilizers for one currant bush is 60-75, 30-40 and 60-100 grams, respectively, however, depending on the state of the plant, this rate may decrease slightly or, conversely, increase. Top dressing should be carried out annually, but if a sufficient amount of mineral and organic fertilizers was applied to the ground during planting, then in the first two years there will be enough nutrients in the soil.
