General Information

PHC for Trees 27-9-9 is a water-dispersible product formulation that provides both chemical and biological fertility. Its chemically-based elements address trees’ immediate nutritional needs, while its beneficial microbes will help to sustain fertility over the long term. Key elements are finely ground so that the product will not clog equipment. A new surfactant technology (RZ3) helps the product to readily penetrate soil. PHC for Trees 27-9-9:

- Is a high nitrogen fertilizer ideal for spring applications or other situations where high nitrogen levels are preferred

- 50% of its nitrogen is in a slow-release form, following ANSI A300 recommendations

- Provides both macro- and micronutrients to replenish seasonal (short-term) fertility requirements and promote growth, health and vigor

- Provides select microbes that fix atmospheric nitrogen, solubilize phosphorus and release bound mineral elements in soluble form through decomposition of organic materials for long-term fertility benefits

- Can be applied by soil injection or by drench

- Is compatible with PHC Injectable for Trees and other mycorrhizal fungal inoculant products
