Silage Corn Crop Study Results
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 silage
corn trials completed in conjunction with the University of
Warwick. Corn harvested for silage is an important feed for
animals, and the European Union grows 5 million hectares of silage
corn annually.
By utilising recognised trial protocols, polyhalite was tested
as a source of potassium on silage corn against standard muriate of
potash ("MOP") and sulphate of potash ("SOP"). This trial further
demonstrated the improved macro-nutrient uptake that is offered by
polyhalite, which has also been evident across the agronomic
programme. Polyhalite achieved favourable results in various
capacities including:
-- Being supportive of nitrogen uptake which appears to be
linked to polyhalite's readily available nutrient release rates.
This showed a 52% increase in nitrogen use efficiency;
-- Potassium is the most demanded nutrient by corn and
polyhalite supports 44% greater uptake compared to MOP;
-- Polyhalite seems to be the preferred source of
macro-nutrients for silage corn, consistently improving nutrient
uptake;
-- Polyhalite delivered a 38% increase in dry matter yield over MOP;
-- Tissue nutrient uptake measurements significantly increased
over MOP (between 28% and 52%); and
-- Polyhalite validated to increase crude protein content over MOP and SOP.
Chris Fraser, Managing Director and CEO of Sirius,
commented:
"Our latest study offers further validation of the agronomic
benefits of polyhalite. The improvement polyhalite can offer to
nitrogen use efficiency is very significant in terms of its benefit
to both crop yields and the wider environment.
"Following the success of our maiden animal feed sales
agreement, it is also encouraging to see how the benefits of
polyhalite's high nutrient value can be further shared across the
food supply chain in such a major crop for animal feed."
