Ca/B
GROGREEN Ca/B is a highly concentrated calcium fertilizer in gel form combined with boron that is quickly absorbed and assimilated by the plant.
Calcium and boron are structural components in cell walls. Deficiencies of these elements will compromise the plant cell wall integrity leading to quality issues of the marketable products such as blossom end rot, tip burning, bitter pit or internal browning.
Calcium improves the quality and consistency of the fruits and prevents decay, while boron improves the synthesis and transport of sugars. These factors increase the fruit set rate, yield and quality of the fruits.
The combination of calcium and boron in one product also allows to alleviate boron toxicity symptoms. The calcium induced plant protection mechanisms through the accumulation of proline, total soluble carbohydrates and photosynthetic pigments in leaves.
