NEPEÑA DATASET: SOILS

Soil Productivity

The level of productivity of different soil types within the Nepeña Valley is provided as an AutoCAD (Release 12) .DXF file. The layers in this drawing, their colors, and the information contained on each are as follows:

SOIlS (orange): AutoCAD open polylines that delimit the extents of different soil types within the survey area.
SOIL_NAMES (white): AutoCAD text strings that provide the designated label for each soil type. The labels follow the ONERN (1972)* soil classification as described in the table below. This classification originally applied only to cultivable areas, and was extrapolated for the rest of the survey zone. Further information on how this was done can be found in Chapter 7 of the dissertation associated to this dataset.

CODE	SOIL (ONERN 1972)*	FAO CLASSIFICATION
LC	Lacramarca	Eutric fluvisol
PL	Palenque	Eutric regosol
MO	Motocachi	Eutric regosol
RI	Ribereño	Eutric fluvisol
