Pursell Agri-Tech and Yara International introduce a new controlled-release fertilizer for turf

Pursell Agri-Tech and Yara International released PurMidas, a controlled-release fertilizer specially designed for turf that delivers a seven-to-one ratio of N to S for optimum growth, aesthetics and performance.

“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, CFO of Pursell.

Formulated as a homogeneous granular fertilizer, PurMidas delivers uniform amounts of nitrogen, available from multiple sources including urea and ammoniacal and sulfate sulfur on each particle to prevent nutrient segregation. This then enhances the consistency of spreading without noticeable striping and irregular growth patterns.

According to the company, PurMidas ensures an optimal supply of nitrogen that is critical for chlorophyll and protein formation for stimulating growth and building strong turf. The soluble sulfur component of PurMidas is readily available for uptake to maximize green-up and enhance plant stress tolerance.

Studies show that, compared to uncoated urea, Pursell controlled-release products minimize leaching by up to 27 percent, reduce volatilization by up to 95 percent and lessen N2O emissions by up to 45 percent.

The fertilizer’s patented 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 also protects granule integrity, eliminates risk of lock-off, minimizes nutrient loss and significantly reduces environmental impact.
