Detailed Guide to Preparing Nutrient Soil for Watermelon Seedling Cultivation

(Agricultural Wealth Network) The structure and composition of nutrient soil have a direct impact on the growth of watermelon roots and seedlings. The nutrient soil used for seedling cultivation should be fertile and loose, with comprehensive nutrition, good water and fertilizer retention, free of pathogens, insect eggs, and weed seeds, and without hard objects such as stones. The dosage is 0.25 kg of urea, 1 kg of superphosphate, and 0.5 kg of potassium sulfate per 1 cubic meter of seedbed soil, or 1.5 kg of nitrogen-phosphorus-potassium ternary compound fertilizer. Seedbed soil disinfection should be carried out when necessary.
