Explain how flooding rice fields reduces the need for herbicides and pesticides in rice farming.

Answer 1

Flooding rice fields provides a natural way to control weeds and pests, which reduces the need for herbicides and pesticides. Water covering the field drowns out and suffocates weed seeds, preventing them from sprouting and competing with the rice plants for nutrients and sunlight. Additionally, the presence of water is an effective way to control pests, as it deters the growth and movement of insects and other organisms that could damage the rice crops. By relying on natural methods to manage weeds and pests, farmers can reduce their dependence on harsh chemical agents that can have negative impacts on human health and the environment. This also promotes sustainable agriculture practices that are more friendly towards the environment.
