Annotated sketch of soil profile (include information on horizon depths (including the litter layer), the
boundaries between horizons – sharp or merging, smooth or irregular, presence of cemented layers, structures,
pores and channels and variation in colour in different parts of the soil – especially streaks or mottles as well as
any other distinctive features of the profile – try to identify the bedrock type for example):

See Field trip handout for information on how to complete this table.
For each horizon give information on:
a) soil structure (shape, size and distinctness of structural aggregates):
b) moisture and consistence:
c) organic matter:
d) fauna – comment on type and amount:
e) pores and channels:

Infiltration
Plot a graph of infiltration rate (mm hr-1) against time for each of your infiltrometer experiments. You may want
to plot all data on one graph (see handout as an example). Then calculate the mean steady-state infiltration rate.
Final steady state infiltration rate (mm hr-1):
