Mr. Gu from Nanjing, Jiangsu Province, asked if they had shallow water in Putian and deep water in Putian. Are there any differences in fertilization? Why do you still want to lime the soil before planting?
A: Shallow paddy fields can be applied to compound fertilizers as well as fertilizers. Drainage before application, shallow water fertilization, restore the water layer 2 days after application. In deep-water fields, it is better to use mixed fertilizer and mud to prevent the fertilizer from floating. Lime before planting is due to its role in regulating acidity in the soil and disinfecting the soil because it applies to acidic soils in the south and year after year.
