Information on SOILSERIES and HORIZON data products
SOILSERIES and HORIZON data products are tabular data that can be used in conjunction with
any of the NATMAP products except NATMAP soilscapes. There are multiple attribute
datasets, which are outlined below. Each is used in assessing
or modelling the capability or vulnerability of land. SOILSERIES info provides
basic information on the soil series, including the modern definition of
the soil. SOILSERIES pesticides includes information useful for pesticide
control such as pesticide leaching and runoff classes. SOILSERIES hydrology
provides extensive information (17 properties) on the water regime, moisture
release and hydrology of each soil. SOILSERIES leacs provides information
on the shrink-swell and corrosivity of the soil to Fe and Zn. HORIZON fundamentals
includes very detailed descriptions of the texture and structure of each soil horizon, while
HORIZON hydraulics provides a range of hydraulic properties, for example water content
for each of these layers.
This page outlines the data contained within the following products.
