Application and benefits

Fertibor® is a free-flowing, highly soluble granular material that leaves no residue. As a versatile source of elemental boron, Fertibor is a valuable addition to solid, liquid, or suspension fertilizers.
 
Because Fertibor granules are free flowing and consistently sized, they are easy to handle, whether pneumatically or mechanically. This property makes Fertibor an asset for granulated compound fertilizer manufacturers.

The product can also be applied directly to the soil, to correct boron deficiency in perennial plantation crops. Or mix Fertibor into solid growing media or composts—the product is a popular choice for palm oil crops, for example.

The dosage rates for young and mature oil palm depend on the soils and the yields of the new planting materials, but the standard application in young oil palm is 1.76 oz (50 g) per palm in the first year, increasing to 3.5- 7 oz (100 to 200 g)  per palm each year for the next three to five years. After that, Fertibor can be applied regularly, depending on leaf analysis results and visual symptoms in the field.

To calculate the amount of Fertibor required, multiply the elemental boron required by 6.6.
