Study Shows Minimal Leaching for ThermoPotash compared to a Loss of 26% of KCl
December 16 2010 - 3:04PM
Marketwired
Amazon Mining Holding Plc (TSX VENTURE: AMZ) ("Amazon" or the
"Company") is pleased to report the results of the potassium
leaching test, which established that ThermoPotash suffers minimal
nutrient loss as a result of leaching, whereas KCl loses 26% under
the same conditions.
Nutrient leaching is a significant factor that decreases the
efficiency of fertilizers for farmers. Potassium is a nutrient that
is found in soil solution in ionic form, possessing high mobility
and susceptibility to leaching, particularly in areas with high
rainfall and sandy soils with low cation exchange capacity (CEC).
This is particularly important in the Cerrado region of Brazil. The
highly weathered ancient tropical soils of Cerrado are very well
drained, not retaining water or nutrients, unlike the younger soils
in the world's traditional farmlands located in temperate climates.
To compound the problem, Brazil's Cerrado region receives
substantially more rain than other growing areas.
The experiment was carried-out at the University of Uberlandia
under the direction of Prof. Gaspar Korndorfer in a greenhouse for
18 days, using soil columns (lysimeters) with two different soil
compositions (sandy texture at 15% clay and a clayey soil at 45%
clay) and two sources of potassium (potassium chloride (KCl)
granules and ThermoPotash granules and powder) at a dose equivalent
to 300 kg/ha under irrigation of 300 mm of water.
The results presented in Table 1 show that the amount of
potassium leached from the ThermoPotash was very low compared to
that of potassium chloride (KCl) for both of the soil compositions
tested. In each sample, 26% of the potassium chloride was leached,
while only 0.3% of the ThermoPotash was leached. The superior
behavior of ThermoPotash over KCl in the leaching test can be
explained by its low solubility in water, which still effectively
delivers nutrients to plants (see press release August 11,
2010).
Table 1: Amount of potassium in the soil solution (leached) collected in two
soil types (sandy and clay) for granular KCl and powdered and
granulated ThermoPotash applied to the surface at a dose equivalent
to 300 kg/ha K2O, after an irrigation of 300 mm, measured during a
period of 18 days.

Note: Figures in parentheses represent the percentage of K from
the fertilizer applied that was lost through leaching and
calculated using the following equation: % K lost by leaching = ((K
leached from the source (g) - K leached from the control (g)) /
total K applied in fertilizer (g)) x 100.
