The last two seasons have represented the most challenging export programs for cherry production in our country, both marked mainly by the Covid 19 pandemic, which generated significant logistical problems in the arrivals of our fruit in the main destination markets, causing serious problems with the condition of the fruits of those varieties produced in semi-late and late areas, where Lapins - the main variety planted in our country - together with Regina - the main variety established from the Ñuble region to the south, were the ones most affected by the long waits at their destination.
Although the rise in export costs and the delay in the logistics and distribution of cherries caused serious problems in their optimal marketing, it should be noted that these are factors that do not necessarily correspond to or depend on the quality of the fruit.
Aware that logistical factors, as well as the context of the global pandemic, are beyond our control, Aminochem has focused on working on the agronomic factors of the crop, mainly those that affect the quality of the fruit and the vigor and health of the orchards. Through its Technical and R&D Department, together with the professionals responsible for each area, it has generated, for several consecutive seasons, studies aimed at validating the use of the biological soil activator. BIOAMINO-L ®, together with applications via fertigation and foliar sprays of AMINOTERRA®, added to the use of root biostimulant AMINOROOT®.
The development of the AminoChem program has allowed to optimize the absorption of nutrients and water by developing more efficient roots, achieving statistically significant results in the concentration of Arginine (mg/g) in roots, as well as the monitoring of the concentration of Starch (%) in flower buds. The information obtained in each of the field trials has allowed to explain the increase in production, such as the considerable increase in the parameters of quality and condition of fruits, sustained increase in beneficial microbiology at the soil level, higher concentration of dry matter in fruits, among other parameters evaluated once the application programs were completed in the different varieties evaluated.
In terms of fruit quality and condition, with the AminoChem program treatment, statistically significant results were observed on the variables of fruit weight and size. In addition, a positive change was observed in the size distribution, an increase in the dry matter content and a decrease in the percentage of fruit moisture, without observing negative results that affected the variable of fruit firmness.
