Paddy fields are flooded agricultural lands specifically used for growing rice. These fields are typically found in regions with a warm climate and abundant water supply. The water helps to control weeds and provides the necessary moisture for rice plants to thrive. Farmers prepare paddy fields by leveling the land and creating bunds, or small dikes, to hold water. The fields are usually planted with rice seedlings, which are submerged in water until they mature. This method of cultivation is essential for producing a significant portion of the world's rice supply.
