Which method can be used for conserving soil moisture?

Using mulch to reduce evaporation is an effective method for conserving soil moisture. Mulch acts as a protective layer on the soil surface, preventing direct exposure to sunlight and air, which significantly reduces evaporation rates. This layer helps maintain soil temperature and moisture levels, promoting better water retention. By minimizing water loss from the soil, mulch contributes to improved moisture availability for plants and supports overall soil health.

Other methods, such as using synthetic fertilizers or applying biopesticides, do not specifically address moisture conservation. Over-irrigating the soil, on the other hand, can lead to waterlogging and other negative effects, which can harm plant roots and lead to reduced soil health. Thus, the use of mulch stands out as a targeted and effective strategy for conserving soil moisture.
