Hou-Actinite 5-4-0 is a 100% bio-based granular fertilizer derived entirely from activated sewage sludge, making it a sustainable option for turf, ornamental, and landscape applications. With 5% total nitrogen (majority as slow-release water-insoluble nitrogen), 4% phosphate, and 1.25% iron, it supports consistent turf health and green-up while improving soil biology. Its organic matter content and high water-insoluble nitrogen fraction allow for extended feeding and minimized leaching, suitable for environmentally sensitive areas and regenerative soil health programs.
