Borium
Trace element

Borium is an essential trace element for the plant. It plays a big role when it comes to the firmness of the cell. Borium improves the absorbation of phosphate by plants. However, an excess of borium can easily cause crop damage. If the value for the content of borium is ample or high (soluble in water) then damage caused by an excess amount of borium will occur less rapidly. The content of borium in the soil changes annually because namely on sandy soils, borium washes out quite easily. During the flowering period, crop absorb the greatest amount of borium. Borium is not very essential for grassland or grain crops. It is important, though, for a pasture with a basis of grasses and clover (ecological pastoral farming). A sensitive crop, for example, is maize, where a lack of borium can immediately be noticed through the position of the ears on the corn-cob. Especially at the top it can be seen on the corn-cob that there are still open places left. For beetroot, celeriac and cauliflower, brown heart occurs. Borium is also important namely to the following crops: chicory, clover, cucumber, radish, spinach and tomato. Lack of borium occurs with pear and apple through internal and/or external cork in the fruits. Borium is also very welcome for plums and cherries. Of all the existing crops, potatoes and sunflowers absorb the biggest amount of borium. Borium is present in small amounts in organic fertilizers and also in a small number of mineral fertilizers.
