Celebrating 145 years of Rio Tinto's borates business.
As one of the chemical elements that make up our planet, boron is all around us—in soil and water, plants and animals—in trace amounts.
Orange, Virginia (1970): Yield was significantly improved
Alfalfa has a higher boron requirement than most crops. For optimum yields of high quality alfalfa, it is essential to maintain adequate supplies of available boron throughout the growing season.
Ammonium pentaborate is a product resulting from the controlled reaction of ammonia, water, and boric acid.

Solubor is highly water soluble, and is commonly applied in foliar sprays. Because the season for the most effective foliar application of boron is short, foliar sprays must be prepared quickly and accurately.
Apples require an adequate supply of available boron, especially during flower formation and fruit set. Foliar sprays of Solubor during the dormant season, pre-pink and early bud stages will ensure an adequate supply of boron during the critical stages of flowering and fruit development.
Certain crops are more at risk for boron deficiency than others. Fortunately, refined boron can help.
South Africa (1989-90): Best yield was achieved with applications at first bud break
Mexican customers have seen improvements in flowering and fruiting quality thanks to the use of refined boron from U.S. Borax.
