Il Calcium treatment in olive groves not only improves the plant's response to water stress, but also optimizes the morphology of the fruit, providing the olive tree heavier drupes has always been higher oil yield.
This is the result obtained from a study campaign between Spain e Portugal, lasting three years, led by Agronomic Department of Strategic Consultants Juan Vilar, connected to various research centers.
Greater profitability
In particular, by using this treatment, according to the research, the profitability of a farm can be improved by almost 20%, through an increase in the size of the drupe and the oil yield, together with a better vegetative and nutritional response of the olive tree, in exchange for an expense that varies depending on the cultivation model, position, harvest time, variety, etc.
The aim of the study was to focus on theeffectiveness of calcium treatment, with respect to water consumption, adaptability to the environment and the improvement of parameters related to productivity and crop quality. In the tests carried out, the use and effect of the application of calcium (OmyaPro Calcium) were generally evaluated in different plots of olive groves, leaving a part exempt for the relative comparison.
Longer veraison
The treated olive trees showed a lower maturity index compared to the untreated ones, in response to the better water status of the fruits, and the olive remained in veraison for longer, allowing for greater harvesting flexibility.
Average weight gain was at least 5%, thus ensuring greater productivity per unit of surface area. In the data referring to production, the average harvest of olive trees treated with the product was 54,3 kg/olive tree compared to 49,4 kg/olive tree of untreated olive trees. Regarding the percentage of oil, the treatment improved performance by up to 3,04%.
