Aquabor® MSR is a multipurpose product with general applications in industrial and consumer products. It is a mild alkaline salt composed of a fine white powder that dissolves easily in water. Aquabor® dissolves even in cold water, with the maximum possible dispersion and solubility rate to obtain supersaturated solutions with high concentrations of boron.

In addition to its already established use as a spray on farms, it can be used in various ways in agro-industrial markets. Minera Santa Rita S.R.L. produces its Aquabor® in a modern spray-drying plant built entirely of 316L stainless steel, which guarantees high purity without contamination.



Aquabor® is available in 25kg polypropylene bags and 680.40kg bulk bags. Its pH is of pH = 8.5 (5% by weight in solution at 22 ° C) pH = 7.3 (10% by weight in solution at 22 ° C).


Applications and benefits



Used as a fertilizer, this product also acts as a plant growth regulator. The ideal application method for correcting boron deficiencies is foliar.
It is also used as coating of finished solid fertilizers, in high performance liquids formulations containing either boron alone or a combination of nutrients for spraying, fertigation or irrigation.


Correcting Boron Deficiency

In solid or liquid fertilizers,  Aquabor MSR is applied to the seedbed in annual crops or under the foliar canopy of perennial crops. Perennial and annual crops can also be sprayed with boron containing solutions.
These are normally tank mixed with other micronutrients or with agrochemical products.
