When it comes to lawn care, providing the right nutrients at the right time is crucial for both newly planted and mature lawns. The Andersons SmartPhos DG® 4-22-0 fertilizer is designed to meet these needs with its innovative, professional-grade formulation. Derived from struvite and powered by patented SmartPhos® technology, this high phosphorus fertilizer offers a game-changing approach to phosphorus applications.


What’s Wrong with Traditional Phosphorus Sources?

Traditional phosphorus products are typically categorized one of two ways — as rock phosphates, which deliver low solubility and low availability but are not prone to tie-up in soil, or as soluble phosphorus, which offers solubility and availability but tends to tie-up in soil.

SmartPhos DG® 4-22-0 stands out from traditional phosphorus products due to its unique composition. Made from struvite, this fertilizer features a highly plant-available form of phosphorus that won't leach or become tied up in the soil. This stability is essential for maintaining nutrient availability, regardless of soil pH levels, ensuring your lawn receives the phosphorus it needs to thrive.


Balanced, Slow-Release Nutrition

One of the key benefits of SmartPhos DG® 4-22-0 is its balanced, slow-release formulation. Thanks to the patented SmartPhos® technology, this fertilizer offers low water solubility, which allows for a slow and steady supply of nutrients over an extended period. This means that your lawn can benefit from a consistent feeding of phosphorus, promoting healthy root development and robust growth.


Exceptional Coverage and Efficacy

SmartPhos DG® 4-22-0 is designed for superior coverage and enhanced efficacy. With its extremely small particle size, SmartPhos DG 4-22-0 offers more complete and uniform coverage compared to traditional fertilizers. Made with The Andersons patented DG Technology, each granule disperses into thousands of microparticles upon contact with water. This ensures that the nutrients quickly move through the turf canopy into the root zone. This efficient delivery system maximizes nutrient uptake and minimizes waste.


Ideal for Various Lawn Conditions

Whether you are establishing a new lawn or maintaining an existing one with phosphorus needs, SmartPhos DG® 4-22-0 is the ideal choice. For newly planted lawns, its low salt index ensures that it won't burn new seedlings, allowing for safe and effective application. In mature lawns with low phosphorus levels, this fertilizer supports ongoing health and vitality. Additionally, SmartPhos DG® 4-22-0 is recommended for use ahead of nutrient blackout periods, ensuring your lawn remains nourished during critical times.
