Corn and Rice Crop Study Results
-- Polyhalite outperformed MOP in corn, improving cob height by
9% and reducing the severity of sheath blight by 71%
-- Polyhalite supports an average 38% increase over MOP in
potassium uptake in rice and improves micro-nutrient uptake from 5
to 27%
The Directors of Sirius Minerals Plc (AIM: SXX, OTCQX: SRUXY)
("Sirius" or the "Company") provide an update on the latest results
from its ongoing global crop study programme.
This update provides results from the recently completed corn
study at the Sichuan Academy of Agricultural Science and the rice
study undertaken with Nanjing Institute of Soil Science.
Corn is the largest cereal crop in the world, demanding 7.33
million tonnes of MOP, which is the equivalent to 31.4 million
tonnes of polyhalite. Cultivated rice in China represents 18% of
the global hectares grown, equating to over 200 million tonnes
annually.
In relation to the corn study, MOP was compared to polyhalite as
the K source and measured the above ground corn biomass, plant
height, cob height and resistance to disease (sheath blight). The
study revealed a decrease of 14% of yellow leaves, and an increase
of healthy (green) leaves by 8%.
In relation to the rice study, MOP was compared against
polyhalite as the K source, but also measured the percentages of
individual nutrient uptake for both the macro- and micro-nutrients.
Polyhalite supports a 4% yield premium at recommended 90 kg K(2)
O/ha over MOP and increased nutrient uptake of K by 38%. Polyhalite
was also shown to improve the micro-nutrient uptake of manganese by
27%.
Chris Fraser, Managing Director and CEO of Sirius,
commented:
"Another strong performance from polyhalite on such widespread
and important crops is welcome and will continue to aid our
discussions with current and future customers."
