Pursell Agri-Tech, Sylacauga, Ala., and Yara International ASA, Oslo, on Jan. 23 announced the availability of PurMidas™, a controlled-release fertilizer specially designed for turf that delivers a 7:1 ratio of nitrogen to sulfur.
The product is formulated as a homogeneous granular fertilizer and includes nitrogen and sulfur on each particle, which the partners said prevents nutrient segregation, enhancing the consistency of spreading without noticeable striping and irregular growth patterns.
“This partnership brings together Pursell’s innovative coating technology and Yara’s proven nutrition solutions to provide customers with a competitively priced product that more fully meets their needs for both nutrient delivery and sustainability,” said Joe Brady, Pursell CFO.
PurMidas ensures an optimal supply of nitrogen that is critical for chlorophyll and protein formation for stimulating growth and building strong turf, according to the partners, who said the soluble sulfur component is readily available for uptake to maximize green-up and enhance plant stress tolerance.
Pursell said its coating technology offers users the flexibility to adjust coating weights and tailor nutrient release rates to meet nutrient demand and soil temperatures of any region. It said it also protects granule integrity, eliminates risk of lock-off, minimizes nutrient loss, and significantly reduces environmental impact.
Pursell said when compared to uncoated urea, its products minimize leaching by up to 27%, reduce volatilization by up to 95%, and lessen N2O emissions by up to 45%.
