Advanced Technologies, a leading manufacturer of slow- and controlled-release
fertilizers and micronutrient products, has added three coated-potassium
sulphate (SOP) products and one coated-potassium magnesium sulphate (K-Mag)
product to its line of POLYON®
controlled-release fertilizers. The new
fertilizers feed the plant's rootzone slowly and consistently with the
potassium needed in order to thrive.
fertilizers release potassium too quickly for plants to use it all,
particularly in potted mediums where soils percolate high amounts of water.
POLYON controlled-release fertilizers have a coating that allows gradual,
consistent release of potassium, so one application can last the entire crop
