HOUSTON (ICIS)--Following a 30-month field trial using coffee crops, Verde Potash has determined that its new non-chloride potash is more efficient and generates equivalent yields while requiring lesser amounts of the nutrient, the Brazilian fertilizer company announced on Thursday.
According to Verde, the new 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 such as potassium sulphate (SOP) and potassium nitrate (NOP).
Beginning in 2010, Verde joined with The Agricultural Research Company of Minas Gerais to start trials whereby coffee plots were treated with either the ThermoPotash formulation or potassium chloride (KCI).
According to officials, the sites using the new application were given 80g per tree while those receiving traditional potash were applied at a rate of 220g. The data showed that yields from both plots were similar.
Beyond counting the number of beans harvested, Verde officials said previous research has shown that chloride causes a reduction in the quality of coffee. With no chloride contained in the ThermoPotash, the company feels the use of the new fertilizer will greatly improve the quality of coffee products for consumers.
Beyond its effectiveness in the fields, the fertilizer results are seen as a positive development in that it demonstrates the potential to reduce the number of applications needed during a growing season.
“The tests concluded that TK is an efficient source of potash and also a source of calcium, magnesium and silicon. TK was applied only once at the beginning of the 30-month test period while KCI was applied to the field on four separate occasions, replicating what occurs in real world farming where seasonal KCI applications are standard practice in order to combat the effects of leaching,” said Verde in a statement.
Verde is presently developing the Cerrado Verde project, which is anticipated to be a very extensive potash deposit and will be used to produce KCI.
