Why is organic matter added to the soil?

Because organic matter releases acids in the soil

The correct answer is option 2. Because organic matter releases acids in the soil.

While organic matter decomposition can release some organic acids, because organic matter releases acids in the soil is not the primary reason for adding it.

The main purpose of adding organic matter is to improve the overall health and fertility of the soil, as we discussed earlier.

Here's a breakdown:

Organic acids: While some organic acids are released during decomposition, they typically don't have a significant impact on overall soil pH.

Soil health benefits: Organic matter plays a crucial role in improving soil structure, water retention, nutrient availability, and fostering beneficial soil life.

Adding organic matter can have a complex effect on soil pH, depending on the type of organic matter and the existing soil conditions. In some cases, it might lead to a slight decrease in pH (more acidic), but this is not the primary benefit.
