When describing Cr and R at depth, what documentation should be included?

When discussing the documentation necessary for describing Cr (a concreted layer) and R (bedrock) at depth, the correct choice emphasizes the importance of detailed notes or additional explanations that should be recorded on the back of the soil profile description sheet. This is crucial as it allows for thorough documentation of observations and measurements that may not fit neatly into the standard categories or boxes provided in a soil judging form.

Including additional notes on the back enriches the description by providing context or observations related specifically to the soil's characteristics at different depths. This could encompass unique features of the Cr or R layers, variations in texture, or other properties observed during the soil profile assessment that are significant for the analysis or for ensuring consistency in data interpretation.

While maps, texture classifications, and color charts contribute valuable information to soil analysis, they don't directly address the need for specific observations related to depth or layers, which is why the inclusion of such details on the back is particularly relevant in this context.
