To tackle the question, I’ll first recall the four classic soil-forming (pedogenic) processes commonly discussed in soil science and attributed to soil genesis frameworks: additions, losses, translocations, and transformations.

Option 1: Transmutations. This term is not part of the standard quartet of soil-forming processes and is not typically listed among Lybrand’s Week 3 Part 1 module concepts. In other words, transmutations is not recognized as one of the core processes in pedogenesis.

Option 2: Additions. Additions refer to inputs added to the soil system from outside, such as dust deposition, organic matter from litter, or human inputs. This is a core soil-forming process and is commonly discussed as an example of material input to soils.

Option 3: Translocations. Translocations describe the movement of soil constituents from one horizon to another within the soil profile, such as illuviation or eluviation. This is a fundamental step in shaping soil horizons and is regularly included in discussions of soil formation.

Option 4: Transformations. Transformations cover chemical, biological, or physical alteration of materials within the soil, such as weathering of minerals or decomposition of organic matter. This is another core pedogenic process widely acknowledged in soil science.

Option 5: Losses. Losses pertain to material removal from the soil system, like leaching of soluble nutrients or erosion losses. This is a standard process in soil formation and flux budgeting.

Given these clarifications, the option that does not belong to the recognized soil-forming processes is Transmutations, since it is not part of the accepted quartet (additions, losses, translocations, transformations) used to describe pedogenesis.
