Consider the following statements:
1. Decomposition of dead material and formation of complex organic matter is called humification.
2. Break down of organic matter and subsequent release of nutrients into the soil is called mineralization.
Which of the statement(s) given above is/are correct?
Both 1 and 2
None of these
Successive decomposition of dead material and modified organic matter results in the formation of a more complex organic matter called humus. This process is called humification. Humus affects soil properties.
Soil organisms, including micro-organisms, use soil organic matter as food. As they break down the organic matter, any excess nutrients (N, P and S) are released into the soil in forms that plants can use. This release process is called mineralization. Hence, both the statements are correct
