Fertilizers usually used for best harvests of black currant

23 February 2023

Black currants are heavy feeders and require adequate nutrients to produce high-quality fruit. A well-balanced fertilizer regimen is essential for optimal growth and maximum yields. In this article, we will discuss the different types of fertilizers that are best suited for black currant production.

    Nitrogen (N) Fertilizers: Nitrogen is an essential nutrient for plant growth and is critical for the formation of leaves, stems, and roots. Black currants require a steady supply of nitrogen throughout the growing season to promote vegetative growth and fruit production. The application of nitrogen fertilizer should be done in two stages: the first application in early spring, just before bud break, and the second application in early summer after fruit set. Nitrogen fertilizers can be organic or synthetic, and the choice will depend on the grower's preferences.

    Phosphorus (P) Fertilizers: Phosphorus is essential for root growth and flower development. Black currants require a moderate amount of phosphorus, and it is recommended to apply a balanced fertilizer that contains both nitrogen and phosphorus. The application of phosphorus should be done in early spring, just before bud break.

    Potassium (K) Fertilizers: Potassium is essential for plant growth and is involved in various physiological processes, including water regulation, photosynthesis, and stress tolerance. Black currants require a significant amount of potassium, and it is recommended to apply a balanced fertilizer that contains all three major nutrients (N-P-K). The application of potassium should be done in early summer, after fruit set.

    Organic Fertilizers: Organic fertilizers, such as compost and manure, are excellent sources of nutrients for black currants. They not only provide essential nutrients but also improve soil structure and fertility. Organic fertilizers can be applied at any time during the growing season, but it is recommended to apply them in early spring.

    Foliar Fertilizers: Foliar fertilizers are liquid fertilizers that are applied directly to the leaves of the plant. They are a quick and efficient way to provide nutrients to the plant and are particularly useful in correcting nutrient deficiencies. Foliar fertilizers can be applied throughout the growing season, but it is recommended to avoid spraying during the hottest part of the day.

In conclusion, black currants require a well-balanced fertilizer regimen that provides adequate amounts of nitrogen, phosphorus, and potassium throughout the growing season. Organic fertilizers, such as compost and manure, are excellent sources of nutrients, and foliar fertilizers can be used to correct nutrient deficiencies. It is important to follow the recommended application rates and timing to ensure optimal growth and maximum yields.
