AZOPLON OPTI 8.5 N Calcium Nitrate Solution (17CaO) with boron is a liquid fertilizer for foliar fertilization of fruit trees, berries, field vegetables and plants, especially for species with high calcium and boron requirements. Regular foliar fertilization provides a constant supply of calcium and boron to plants, which is especially important because the transfer of these elements from older leaves to younger leaves is limited. It is recommended to spray healthy and dry plants with an appropriate concentration of solution. Do not use after rain or in heat.

Expert said
Intensive foliar feeding with this fertilizer is recommended in case of difficulties in calcium uptake in the initial phase of plant growth, in case of low yield, in case of high temperature and low precipitation in summer and in case of planned long-term storage of fruits.
The huge advantage of AZOPLON OPTI 8.5 N Calcium Nitrate Solution (17CaO) with Boron is the right ratio of calcium to boron, which improves the utilization of macronutrients in the fertilizer. Thanks to the simultaneous application of nitrogen, calcium and boron, plants that have a higher nutrient requirement for these elements can be fed properly, especially during the critical phases of their growth and development, resulting in increased yields.
| Cultivation | Time of application | Dose of fertilizer (l/ha) | Recommended concentration range (%) |
| Fruit trees and bushes | 4-8 times, every two weeks after the formation of fruit buds | 4-8 | 0,5-0,8 |
| Nurseries with ornamental, fruit trees and forest growing trees | 2-3 times every two weeks | 4-8 | 0,5-0,8 |
| Berries (raspberries, blackberries, currants, blueberries, strawberries) | 2-3 times a week, in the phase of binding and fruit growth | 3-4 | 0,3-0,4 |
