HOUSTON (ICIS)--Fertilizer producer Verde Potash announced on Wednesday that a two-year testing trial in Brazil on sugarcane using its non-chloride potash, called ThermoPotash, has demonstrated that the farmers can reduce the amount of nutrients applied when using the product and achieve increase yields from the crop.

Toronto-based Verde said the advantage is gain in yields because of the fact that ThermoPotash is not leached in water as other potassium salt fertilizers such as potassium chloride and potassium.

Testing has shown that ThermoPotash suffers a loss of approximately 0.3% whereas conventional potash can lose as much as 26% under the same conditions, which is important as the sugarcane crops within Brazil face often heavy rainfall resulting in excessive nutrient leaching.

ThermoPotash (TK) is a controlled released non-chloride multi-nutrient version of potash developed by the company to compete with other premium non-chloride potash fertilizers within the Brazilian market like potassium sulphate (SOP) and potassium nitrate (NOP).

It has been designed to deliver the nutritional needs of crops in the unique Brazilian soils which can be highly acidic. According to Verde, residual potassium levels in sugarcane soils fertilized with ThermoPotash was up to five times higher after the harvest when compared to fields fertilized with conventional potash.

Verde is presently developing the Cerrado Verde project which is anticipated to be a very extensive potash deposit and will be used to produce both the ThermoPotash and potassium chloride (KCI). The project is located in the main region of the nation’s sugarcane production

In Brazil sugarcane is the second most valuable crop produced and covers more than 12.5 million hectares. Brazil is the world's largest producer and exporter of sugarcane, accounting for one third of the world's production, and is the second largest ethanol producer, with sugarcane being used as a feedstock for the fuel. Currently Brazil imports roughly 90% of its potash needs from foreign exporters.
