What is paddy field filling?

Paddy field filling refers to the practice of preparing and managing rice paddies by flooding the fields with water, creating the necessary wetland environment for rice cultivation. This technique helps control weeds, maintain soil moisture, and support the growth of rice plants. The filling process typically involves the strategic management of water levels to optimize conditions for rice growth throughout the growing season. Proper paddy field filling is crucial for maximizing yield and ensuring healthy crop development.
