(69) PFH pit ID (same as in BioSoil)<br />
(Soil Water, Soil)<br />
In general, samples from at least 3 pits on each depth with replicates are taken for the<br />
soil water determination. The PFH pit ID is the Pit ID of the main pit on the plot for<br />
which the profile description was made and submitted with the PRF and the PFH file. In<br />
case that the profile description was made already during the BioSoil project or during a<br />
comparable assessment it is the same ID.<br />
The linkage between Soil Water data (SWC form) and Soil Profile description data<br />
(PRF and PFH) is built by a combination of the data fields , , , and .<br />
(70) SW pit ID<br />
(Soil Water)<br />
In general, samples from at least 3 pits on each depth with replicates are taken for the<br />
soil water determination. The Pit ID of the actual Soil Water pit indicates where the soil<br />
water sample was taken. In case that this pit is the one on the plot for which the profile<br />
description was made (submitted with forms .PRF and .PFH) it is the same as the PFH<br />
pit ID (see (69)). In all other cases it is a new one.<br />
Soil Water data from SWC and SWA forms are linked using the combination of the data<br />
fields , , (70), (71), and<br />
.<br />
(71) Code for depth level – Layers Soil Water D_DEPTH_LEVEL_SW<br />
(Soil Water)<br />
The linkage between the SWA and the SWC table is built by the key parameters of<br />
SWC. This means that each observation/line in SWA can be linked to exactly one<br />
observation/line in SWC by the combination of country, plot, date, SW_pit,<br />
depth_layer, and replicate. Each line in SWC is identified by such a specific<br />
combination of the respective values. Each line in SWA is identified by such a specific<br />
combination of the respective values and, in addition, a specific value for matric<br />
pressure.<br />
This data model implies that the depth layer code must be more or less unique. It is not<br />
possible to have to samples (one from 10 to 20 cm and one from 15 to 20cm) at the<br />
same pit with the identic depth layer code „M12“. Only 3 codes are fixed which are the<br />
mandatory depth layers M02, M24, and M48 (see table below). All others have to be<br />
defined by the submitting partner, making sure that each combination of country, plot,<br />
date, SW_pit, depth_layer, and replicate is unique in SWC and each observation in<br />
SWA can be linked to exactly one observation in SWC.<br />
