Use of micronized-bentonite-sulfur and micro elements (Fe and Zn) mixtures in organic strawberry cultivation

In this study, in organic strawberries grown in the greenhouse five different sulfur products applied to the soil were examined during the two-year growing period. The sulfur products were: 1) Micronized-bentonite-sulfur, 2) Traditional granular sulfur, 3) Micronized-bentonite-sulfur+iron (Fe), 4) Micronized-bentonite sulfur+zinc (Zn), 5) Micronized-bentonite-sulfur+iron (Fe)+zinc (Zn) and without any application control. The effects of the treatments on plant growth, yield and fruit quality properties of strawberry crop, also soil pH, soil Fe and Zn concentrations and plant nutrient concentrations of the strawberry plants were investigated, titratable total acidity, vitamin C, fruit pH and macro and micro mineral concentrations in leaves, and also soil pH, EC, Fe, Zn, Mn, Cu concentrations were examined. Plant growth parameters, total yield, fruit quality characteristics, leaf nutrient concentrations, important in terms of applications differences were detected.
