LONDON (Alliance News) - Sirius Minerals PLC on Tuesday said it has received results from recently conducted trials on soybeans and corn which found polyhalite to be an effective fertiliser for both crops.
Sirius said the soybean trials were carried out by Texas A&M University and the University of Sao Paulo, while the corn study was handled by North Dakota State University.
It found polyhalite improved soybean yield and bean protein yield by up to 16% compared to potash chloride or potash sulphate, while corn yields were improved by 3% compared to potash chloride and ammonium sulphate.
Sirius Minerals is a fertilizer development company focused on the York potash project, which it says has the world's largest and highest-grade deposit of polyhalite, a multi-nutrient form of potash containing potassium, sulphur, magnesium and calcium.
"These trials not only display the potential for polyhalite to provide an increased financial return from higher yields, but also demonstrate important input savings," said Chris Fraser, Sirius' managing director and chief executive.
Shares in Sirius were down 1.4% to 17.25 pence on Tuesday.
