During the rapid growth phase of sweet potatoes, it's recommended to apply a solution made from 25 to 30 times diluted superphosphate mixed with dry and pure plant ash leaching liquid, or 15 to 20 times diluted leaf leaching liquid. This treatment should be applied 2 to 3 times in succession, with about 5 to 6 kilograms per square meter of soil being ideal. Applying this solution helps improve nutrient absorption and supports healthy root development.
After rainfall, when the soil is slightly moist, it's a good time to perform morning and evening sprays. These sprays can effectively eliminate underground pests that damage sweet potatoes, providing natural protection for the crop. For even better results, you can mix in a magnesium sulfate solution at a dilution of 80 to 100 times. This not only enhances pest control but also strengthens the sweet potato plants' resistance to insect attacks, leading to healthier and more resilient crops.
This method is both cost-effective and environmentally friendly, making it a popular choice among farmers who want to maintain high yields without relying on harsh chemicals. By following this schedule and combining the right treatments, you can ensure your sweet potato field thrives throughout the growing season.
