Question

What are weeds?Why do farmers remove weeds from their fields?

Answer 1

Weeds are unwanted wild plants that grow in the field. Weeds compete with the crop for nutrients, light, and space. As a result, crop plants get lesser nutrients, light, and space for their development.
They rob soil moisture and nutrients from the competing crop and decrease harvest efficiencies. Weeds also compete with the crop for sunlight. Because they are plants competing to survive in a limited space, weeds are actively removing nutrients from the soil to grow taller, stronger, and healthier each day.
