High-Nitrogen Performance with Bio-Based Technology — The Bridge Between Premium Feeding and Organic Benefits.
Shaw's 28-0-3 BioNite is a premium high-nitrogen fertilizer that uniquely blends 50% SurfCote polymer-controlled nitrogen with 35% BioNite — a bio-based organic nitrogen source derived from natural materials. This combination gives you the high-performance nitrogen delivery of professional-grade synthetic fertilizer alongside the slow, biological feeding benefits of organic nitrogen, creating a more complete and sustainable nitrogen feeding program than either approach alone.
BioNite nitrogen is released through soil microbial activity, feeding the lawn's soil and breaking down the organic fraction — a fundamentally different and more sustainable release pathway compared to simple chemical dissolution. This biological feeding builds soil health over time, improving microbial diversity, organic matter content, and long-term soil structure. The result is turf that feeds itself more efficiently season after season.
With a high 28% nitrogen analysis and 3% potassium, this is a powerful feeding product for maintaining dense, dark green turf. The 50% SurfCote fraction provides consistent polymer-controlled feeding, while BioNite's organic fraction delivers a biologically active, slow-release of nitrogen. It's the right choice for programs that want elite nitrogen performance with a nod toward responsible lawn care.
