Product

EC FERTILISER

Calcium borate


Nutrients:
7 % Total boron (B) 100 g/l

also contains: 14,6 % Calcium oxide (215 g/l CaO); 1,7 % Total magnesium oxide (25 g/l MgO)


Density: 1,47


pH-Value: 8,5


Color: beige


Storage

Our products are tested between -10 °C and + 45°C and can be stored within this temperature-range. Occurring crystals due to cold storage will dissolve again at higher temperatures. We recommend a frost-free storage and a product-temperature above +5 °C at the time of use.

Miscibility

Lebosol®-Robustus SC is compatible with the common plant protection products. Since not all the influences appearing in practice are predictable, a compatibility test with small amounts of the products provided for the spraying is always useful. Don’t mix with fertilizers containing phosphate or sulfate. In case of mixture with fertilizers or plant protection products fill sprayer up to 2/3 with water and add products separately. Add Lebosol®-Robustus SC as the last component.

Product active agent

Boron availability is low on sandy soil, at high content of nitrogen or calcium, during cold or in waterlogged or very dry soils.

Boron deficiency is shown by bursting of tissue, perishing of the growing points, heart and dry rot, bad blossom quality and reduced fruit setting, deformed fruits.

Calcium availability is low on acidic, sandy or light soil (eluviation), acid peat soils and during aridness.

Calcium deficiency often appears in case of high nitrogen or potash content in the fruit and in big fruits.

Calcium deficiency is shown by tipburn, leaves rolled inwards, damaged growing points, reduced fruit firmness, bitter pit and low storage potential.
