Boro 15 MSR is a natural product with 15% Boron. It is used in agriculture as a fertilizer and growth regulator. The solid granules of Boro 15 MSR are usually applied directly to the soil. In addition, this product provides Sulfur (S) and Calcium (Ca).




Boro 15 MSR is available in 25kg polypropylene bags or in 850kg bulk bags.


Applications and benefits



Boro 15 is a natural fertilizer and the most costefficient way to incorporate Boron through soil for concentration point.



Boron enhances the effects of sugars on the hormone action in plants (highly used in Brazil in citrics production with this end), the amount of photosynthesis, the rate of absorption of CO2 from the air, and the growth of plant roots. Boro 15 is the most appropriate product for fertilizers mixing plants plantas which usually add it to NPK formilations together with other micronutrients.


Boron Deficiency

For decades, Boron deficiency has been recognized in a wide range of crops. This deficiency can be remedied by the correct boron application through soil, foliar or root system application methods. Boron deficiency can be detected on plants symptomatology or by means of soil analysis.


Controlled Release

With Boro 15, the amount of Boron available can be adjusted to improve the assimilation of the plant.
The ability to accelerate or diminish the micronutrient’s release speed results in the
maximum utilization of Boron together with the highest economic efficience. This ability depends on the requirements of each crop.
