FOLIAR FEEDING OF EARLY-RIPENING STRAWBERRY
Growing strawberries under cover makes it possible to get an early berry harvest but requires more serious care before the berries start ripening. Strawberry productivity depends on the formation of leaf surface and flower stalks on the bush. The first indicates the conditions of photosynthetic activity and the intensity of growth processes. The main function of leaves is the proper course of photosynthesis, as a result of which organic matter is formed that goes towards building the bush and forming the harvest. The second indicates the importance of the number of flowers and ovaries.
The microclimate under agrofibre promotes more intensive plant growth and therefore increases the need for nutrients. Considering that the crop is grown mainly on soils of light texture, deficiency appears for practically all macro- and micronutrients, and the acid reaction of the soil solution promotes the spread and development of pathogenic microflora and its colonization of plants.
In covered ground, where strawberry plants are already flowering and berries are forming, we recommend adding to the tank mix ECOLINE Phosphite (K) at 15 ml/100 m2 (per are) of area + ECOLINE Boron (Opti) 20 ml/100 m2 (per are) of area. To improve berry quality, in particular shelf life, at the start of strawberry fruit formation carry out foliar feeding with the special fertilizer ECOLINE Calcium-Boron (Chelates) at 20–25 ml/100 m2 (per are) of area. It is advisable to carry out feeding twice at an interval of 5–7 days.
On areas where the covering agrofibre is removed, the window of opportunity is somewhat wider. On such areas there is still time to feed the plants with fertilizers at 15 ml/100 m2 (per are) of area ECOLINE Phosphite (K) + ECOLINE Magnesium (Chelates) to restrain the development of Oomycete fungi and strengthen photosynthesis.
Treat the plants a second time, to increase berry yield, with the special fertilizer GROS Quiceleum at 15 ml/100 m2 (per are) of area for more abundant flowering and berry formation. After flowering carry out foliar feeding with the special fertilizer ECOLINE Calcium-Boron (Chelates) at 20–25 ml/100 m2 (per are) of area. It is advisable to carry out feeding twice at an interval of 5–7 days.
On all areas after harvest carry out a preventive treatment with the special fertilizer ECOLINE Phosphite (K) at 30 ml/100 m2 (per are) of area.
