What is one of the main benefits of maintaining high organic matter in soil?

Maintaining high organic matter in soil significantly enhances microbial activity, which is crucial for a healthy and functioning ecosystem. Organic matter acts as a food source for soil microorganisms, including bacteria, fungi, and other beneficial life forms. These organisms play a vital role in decomposing organic material, recycling nutrients, and improving soil structure and fertility.

When organic matter breaks down, it enhances soil aeration and water-holding capacity. This creates a favorable environment for root growth and the proliferation of beneficial soil organisms. Increased microbial activity also promotes nutrient uptake for plants, enhances disease suppression, and contributes to overall soil health.

In contrast, options related to nutrient leaching, water infiltration, and pesticide volatility either do not reflect the positive impacts of high organic matter or propose outcomes that are generally detrimental and do not capture the primary functions enhanced by organic matter in the soil.
