Why and how trash mulching is done in sugarcane ?

Within a week of planting, uniformly mulch the ridges with cane trash to a thickness of 10 cm. It aids in drought relief, moisture conservation, weed control, and the prevention of shoot borer infestations. After 21 days of planting in heavy soil and wetland conditions, mulch the field with trash. Avoid using trash mulching in places where termites have been discovered.
