PHTD 5 is a complex fertilizer specifically developed for pre-sowing seed treatment and foliar feeding of corn. It contains a balanced set of macro- and microelements fully matching the nutritional requirements of the crop. The composition includes nitrogen, phosphorus, potassium, sulfur, manganese, copper, zinc, boron, molybdenum, nickel, cobalt, as well as a surfactant. All microelements are presented in easily assimilable chelated forms, ensuring their complete and effective uptake by plants. The fertilizer is characterized by high concentration of active substances, complete water solubility, stability of properties during long-term storage, and optimal pH of the working solution. PHTD 5 has the following physico-chemical properties: nitrogen content — 60 g/l, phosphorus (P2O5) — 78 g/l, potassium (K2O) — 110 g/l, sulfur — 26 g/l, manganese — 6 g/l, copper — 15 g/l, zinc — 25 g/l, boron — 4.5 g/l, molybdenum and nickel — 0.15 g/l each, cobalt — 0.7 g/l. Organic compounds make up 59–60 g/l, surfactant — 20–25 g/l. Fertilizer density varies from 1180 to 1280 g/l, chelation degree reaches approximately 100%, and pH of the working solution is within the range of 7.8–8.5. The recommended dosage is 3–3.5 liters per ton of seeds for pre-sowing treatment and 1–3 liters per hectare for foliar applications. In addition, PHTD 5 promotes improved growth and development of corn, providing a strong root system and high resistance to diseases, lodging, stress, cold, and drought. The fertilizer supports early flowering and rapid water release, which is especially important for achieving high productivity and stable yields. Optimal plant density depends on moisture conditions and ranges from 55,000–60,000 plants per hectare in areas with insufficient moisture to 70,000–75,000 plants per hectare in areas with adequate moisture.
