What can be a consequence of losing soil organic matter?

Losing soil organic matter can lead to reduced soil holding capacity, which is critical for maintaining adequate moisture for plants and supporting overall soil health. Soil organic matter plays a vital role in enhancing soil structure, allowing it to retain water and nutrients more effectively. When organic matter decreases, the soil can become less porous and lose its ability to hold onto moisture, making it more susceptible to drought conditions and limiting the availability of water for plants. This, in turn, can lead to decreased agricultural productivity and increased erosion risks. The other options reflect positive outcomes associated with healthy soil organic matter levels, rather than consequences of its loss, making reduced soil holding capacity the most appropriate answer.
