Customizable Water-Soluble Fertilizer Now Available

Growers who want a single water-soluble fertilizer solution for a wide variety of plants have an efficient, effective option — Peters Excel Cal-Mag Special 15-5-15.

This all-purpose, complete formulation from ICL Specialty Fertilizers features high-nitrate nitrogen and low phosphate with extra calcium and magnesium. It also contains a complete range of essential micronutrients as prescribed by the Peters M-77 chelated micronutrient system, a technologically advanced, proprietary mixture from ICL Specialty Fertilizers that provides plants with essential micronutrient nutrition and trace element sources blended at defined ratios.

“Growing with Peters Excel Cal-Mag Special produces healthy, compact plants over a wide variety of species and cultivars,” said Kurt Brace, ICL Specialty Fertilizers’ ornamental horticulture marketing manager for the Americas. “Growers who want to minimize the number of fertilizers they need to buy throughout the growing season can apply this product and rest assured that their plants are getting the nutrition they need.”

The Peters A B+C patented product selection system identifies Peters products as: All-Purpose Products, Base Products and Customizing products. The use of these products in fertilization programs is determined by irrigation water alkalinity and plant type.

“Peters Excel Cal-Mag Special is ideal for use with Type 2 irrigation water, which the Peters A B+C system defines as having an alkalinity measurement of 60 ppm to 150 ppm calcium carbonate,” Brace said. “This water type is widespread throughout the United States, making Peters Excel Cal-Mag Special a great option for even more growers looking for a one-bag solution.”

Peters Excel Cal-Mag Special is an A (All-Purpose) product, and that means it can be mixed with other products within the Peters Excel line to create a wide variety of programs to fit just about any grower’s needs.
