Which statement about organic matter in soil is true?

Organic matter in soil plays a crucial role in enhancing soil productivity, making the statement accurate. It contributes to numerous beneficial properties that support plant growth. For instance, organic matter improves soil structure by promoting the formation of aggregates, which enhances aeration, water infiltration, and root penetration. This improved structure leads to better water retention and drainage, both essential for optimal plant health.

Additionally, organic matter serves as a source of nutrients for plants as it decomposes, releasing essential elements such as nitrogen, phosphorus, and potassium into the soil. It also supports beneficial microbial activity, which further aids in nutrient cycling and availability to plants.

While organic matter impacts the upper layers of the soil most visibly, its influence can extend deeper, interacting with soil layers below the surface. This engagement with various soil depths contributes to overall soil health and fertility, reinforcing its significance in promoting soil productivity. Hence, the statement regarding its ability to enhance soil productivity is substantiated by its multiple roles in soil health and plant growth.
