Form 5a - ICP Forests

(140) Repetition
(Soil)
This is the order number of the composite when several composites are analysed for the same
plot and depth layer. The first composite is numbered 1, the second composite is numbered 2,
etc.
(141) Layer limit superior/inferior
(Soil)
The upper (lower) limit of the layer depth (in centimetres). The limit between the organic and
mineral layer corresponds to 0 cm. For organic layers (OL, OF, OH, OFH, Hf, Hfs, Hs), the
limits are negative values. For mineral layers (M05, M01, M51, M12, M24, M48) the limits are
positive numbers.
(142) Number of subsamples
(Soil)
Number of subsamples in the composite.
(143) Code horizon (horizon number)
(Soil, Soil Water)
Identification number of the horizon (horizon 1 = 1, horizon 2 = 2, etc.) The horizon is further
indentified by the horizon designation (144) in the xx2009.PFH file.
(144) Horizon designation
(Soil)
The horizon designation is a combination of several symbols:
(144).1 A number that gives information about discontinuities, i.e. the number of materials
in which the soil has formed. This number is stored in the field
HORIZON_DISCONTINUITY.
(144).2 One or two capital letters that designate the type of master horizon (or transitional
horizon). These letters are stored in the field HORIZON_MASTER.
(144).3 Lowercase letters that designate subordinate characteristics of the horizon. These
letters are stored in the field HORIZON_SUBORDINATE.
(144).4 A number that designate vertical subdivisions. This number is stored in the field
HORIZON_VERTICAL.
(144).1 Horizon discontinuity
This field contains a number to indicate a discontinuity in the horizon designation (mandatory if
exists).
• When the soil has formed entirely in one kind of material, a zero (0) is used (the field is
NOT empty).
• When the soil has formed in several materials:
o The upper part of the soil profile (corresponding to the first material) will be
designated without number 1.
o The part of the soil profile corresponding to the second material will be
designated with the number 2.
o The part of the soil profile corresponding to the third material will be
designated with the number 3.
