RE: RE: RE: Drill ResultsTHERMOPOTASH
Amazon is interested in pursuing a pyro-metallurgical treatment process to make a ThermoPotash product or directly combining the verdete with a phosphate rock to create a thermo-phosphate potash. The proposed process is commonly used in production of high quality phosphate. Amazon has been able to access 25 years of agronomical data that suggests that thermo-potash is the ideal fertilizer product for Brazil’s nutrient poor, well drained, acidic soils. Thermo-phosphate is recognized as a premium product in Brazil that has been successfully marketed for over 40 years, it is recognized for its retention time in soils, where heavy tropical rains often wash away super soluable products. Amazon endeavours to introduce a thermo-potash product with similar properties.
Research by Eichler (1983), showed that a mixture of 50% verdete slate and 50% magnesic limestone, burned at 1,1000C is an efficient source of potash. The product considerably increases available levels of potash in soil. Equivalent quantities of thermo-potash and KCl had equivalent yield impacts, despite lower concentrations of potash in the thermo product. In addition, thermo-potash had longer residual impact on crops with successive plantings.
Studies made by Leite (1985) and Valarelli et al. (1993) which included pilot plant and agronomical tests, show the development of “Thermo-phosphate Potash Calcium-Magnesium”, from a mixture of verdete slate, locally available phosphate rock from Araxá, and magnesic limestone. The Leite (1985) process was developed to be a fertilizer with the simultaneous action of correcting the soil acidity, a problem in Brazil’s Cerrado (Savannah) region and many tropical soils globally.

so, is it safe to say it will work again?
hope so!
