Mulching is a helpful technique in farming that involves covering the soil with materials like plastic or biodegradable substances. This method can control soil temperature, retain moisture, reduce weeds, increase crop yield, and protect against pests. Plastic mulch, especially black polyethylene, is commonly used for its effectiveness and affordability. Biodegradable mulches are also used, but they are more expensive and less durable. Research has shown that mulching can benefit horticultural crops in various climates by preserving soil nutrients and improving overall crop quality.
