To obtain a high yield of fruit and berry crops every year, plants must be supplied with an optimal level of macro- and microelements throughout the whole growing season.
Foliar feedings at the end of the growing season, after harvest, are particularly important. 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, growers carry out preventive treatment of trees and shrubs against diseases and feed them with key mineral nutrients 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 sufficient copper content in the soil, special fertilizers with PHOSPHORUS IN THE FORM OF PHOSPHITE at increased doses are used 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.
