The cultivation of strawberries requires special attention to nutrition, as the correct supply of nutrients directly affects the growth of the plants, the yield and the organoleptic characteristics of the fruit. Balanced fertilisation contributes to the production of tasty and marketable fruit, while enhancing the plants’ resistance to diseases and abiotic stresses.
Basic nutritional needs of strawberries
Strawberries, as a demanding crop, need an adequate supply of macronutrients and micronutrients.
- Nitrogen (N): promotes the growth of the leaf surface and shoots. Lack of N can lead to delayed growth and smaller fruits.
- Phosphorus (P): important for root system development and flowering. Phosphorus deficiency can cause reduced fruit set.
- Potassium (K): improves fruit quality, enhances flavour and extends shelf life.
- Calcium (Ca): essential for the structural integrity of cells, contributing to the toughness of the fruit and reducing the appearance of wounds in the fruit.
- Magnesium (Mg) and Iron (Fe): involved in the process of photosynthesis and chlorophyll production.
Stages of strawberry fertilisation
The nutrition of strawberries must be adapted to the different stages of growth.
- Soil preparation: Before planting, it is recommended to incorporate organic matter and basic fertilizers to improve soil fertility.
- After planting: application of fertilizers with high phosphorus content to enhance rooting.
- Period of growth and fruiting: Regular applications of nitrogen- and potassium-rich fertilizers, adapted to the needs of the plants.
Choice of suitable fertilizer: COMPLEMASTER
To meet the needs of strawberries, the COMPLEMASTER of ZIKO S.A. is a complete solution. It is a complex granular fertilizer with a balanced ratio of nutrients, specially designed for demanding crops such as strawberries.
Composition of COMPLEMASTER:
- Nitrogen (N): 12% total, with forms of ammoniacal and urate nitrogen for immediate and prolonged action.
- Phosphorus (P2O5): 12% water soluble, ensuring immediate absorption by plants.
- Potassium (K2O): 17% water-soluble, derived from potassium sulphate, ideal for chlorine-sensitive crops.
- Magnesium (MgO): 2%, contributing to chlorophyll synthesis and photosynthesis.
- Sulphur (S): 25%, improving the availability of other nutrients and soil acidity.
Instructions for the application of COMPLEMASTER:
- Soil preparation: Apply 40-60 pounds per acre before planting, incorporating the fertilizer into the soil.
- During cultivation: Apply 20-30 kg per acre at regular intervals, depending on plant needs and soil conditions.
The use of COMPLEMASTER provides strawberry plants with all the necessary nutrients in balanced proportions, supporting healthy growth and the production of quality fruit.
