Modern intensive strawberry production in the Alpine region increasingly relies on an annual production cycle, starting with the planting of frigo or container seedlings in July–August and ending with the harvest the following spring. This system allows yields often exceeding 1 kg of fruit per plant.
To achieve such results, adequate plant nutrition is crucial. In the early stages, biostimulants (amino acids, humic acids, algae) are preferred, while mineral fertilizers are gradually introduced 7–10 days after planting. In September, plants enter an intensive growth phase – stolon removal and nutrition with nitrogen, phosphorus, and calcium are essential. In October, flower buds differentiate, so fertilization should continue with reduced doses and the addition of boron and humic acids.
Fertigation is the most common way to provide macroelements, while microelements are usually applied foliar. Frequent applications of small doses give the best results. Excessive amounts, especially calcium nitrate or potassium nitrate, may damage the young roots.
Proper fertilization, based on soil analysis and adapted to local conditions, remains the key to high and stable yields.
