Perennial plantings need an especially careful approach to the system of macro- and microelement mineral nutrition throughout the whole growing season. This is due both to the specifics of nutrient removal from the soil and to the phytosanitary conditions that develop in orchards.

Climate change and possibly failure to observe quarantine measures have led to a considerable spread and increased harmfulness of certain diseases. In the system of preventive measures against, in particular, monilia, growers fertilize with chelated nutrients and with phosphorus in the form of phosphite. Such foliar feedings are practiced at the end of the growing season, after harvest.

Why should this be done? Fruit and berry crops begin to form next year's yield in the second half of the growing season, when fruit buds are laid down. Therefore after harvest, trees and shrubs are treated preventively against diseases and fed with key mineral nutrients that are needed both in the current year and after the spring resumption of vegetation:

  • Most often COPPER preparations are used for this purpose, if the content of this element in the soil does not exceed permissible concentrations.
  • With a high copper content in the soil, it is better to use special fertilizers with PHOSPHORUS IN THE FORM OF PHOSPHITE at increased doses for disease prevention. Such fertilizers are especially popular in Europe; their effectiveness has been proven in practice both in the hot climate of Spain and Italy and in countries with a temperate climate (Germany, Poland, the Baltic states).

  • Sufficient BORON NUTRITION of plants in autumn ensures the accumulation of plastic substances (a significant share of which are sugars), which improves frost resistance and resistance to spring frosts and promotes normal development of the future flower.

    Taking into account foreign experience of feeding fruit and berry crops and the results of using fertilizers in Ukraine, ECOORGANIC recommends the following tank mixes for autumn application:

    • with insufficient copper content: ECOLINE Copper (Chelate) 2.0–3.0 l/ha + ECOLINE Boron (Organic) 1.0 l/ha;
    • with sufficient copper content: ECOLINE Phosphite (K) 2.0–4.0 l/ha + ECOLINE Boron (Organic) 1.0 l/ha.
