One of Boron’s major function in plants is in the formation of cell walls through its impact on meristematic activity, essential for cell growth and differentiation. It also plays an important role in the flowering process and fruit set through its effects on pollen germination and the growth of the pollen tubes with consequential effects on yield. Deficiency in Boron also causes inhibition on cessation on root elongation in both the main and lateral roots.

In oil palm, Boron has been found to increase pest and disease resistance. In young nursery palm, Boron deficiency identifies the attack of red spider mites. Boron deficient palm may also produce partly parthenocarpic fruits. Other crops that are susceptible to Boron deficiency include papaya, banana, pepper, durian, water melon, groundnut and a number of vegetables such as celery, carrot and asparagus.

Correction of Boron

For Plants where Boron is phloem immobile like oil palm, application of Boron from a readily water soluble source either by foliar spray or soil application is limited in effectiveness as :

• The Boron applied (much is relatively mobile in the soil) is easily leached and becomes unavailable after a short time.
• Since it is phloem immobile, Boron moves with the transpiration steam in the xylem and gets permanently fixed in the plant tissues especially the leaf tips. Once it is fixed, it cannot be remobilized to supply the need of the other plant tissues.
• The risk of toxicity due to over application of a very soluble source is high as the margin between deficiency and toxicity in most plants in narrow.

One solution to overcome the above issues is by a constant supply of an available form of Boron and in the right quantity at short interval. However this is almost impractical except in the case of hydroponics or fertigation. The practical approach to overcome these problems is by the use of slow release Boron micronutrient.

FS-BOR is processed from Ulexite by undergoing a process of acidulation and granulation in the factory. It contains both calcium and sodium borate. The sodium borate portion is immediately available to the plant while the calcium borate portion is slowly release trough its dissolution with the acidity of the soil. This unique properties of FS-BOR ensure that it satisfies the continuous need of the plant.

FS-BOR is suitable for use in :
• High rainfall area
• Peat soil
• Sandy soil with low organic matter
• High organic soil
• Soil with low Boron
• Soil with high PH
• Low CEC soil
