Produced by USAVINA Co. With the technology of Openamix-Tech-USA(OMSSI)In 1946, an American scientist by the name of Lee Reynolds discovered a formula for a liquid which changed the way of treating soils. He named this product Reynolds Soil Conditioner. This product was used on hundreds of thousand acres of land in the U. S. A.

Later, another American scientist by the name of Everett Storey took over the work of Lee Reynolds. Storey updated the formulation for the soil conditioner and called it Open All(amongothe names). And during the seventies Open All was used on hundreds of thousand acres of land in the U. S. A. And around the world.

During the early eighties, a soil scientist by the name of Michael W. Botts met and went to work with Everett Storey. While working with Everett, he discovered the Open All technology could be used in many ways and in many combinations to obtain great results never before realized. The new formulation had a normalizing effect on most soils and could balance most soil systems. Later, after Everett passed away, Michael W. Botts discovered the beneficial effects the formula had on organic systems including fertilizers.

In the early nineties, Michael W. Botts met Freedom Tran who put this concept and technology to work in Vietnam to produce peat-based organic fertilizers with great success. They named their fertilizers Openamix.

In year 2002, in view of the fact that farmers are plagued with saline and sodic soil problems, we decided to establish Usavina Organic Biochemical Fertilizer Manufacturing&Trading Co. Ltd. In Hong Kong to solve the soil problems and hence improve the livelihood of the farmers. OEM Service:
