Critical slope cut-off for moderately productive land ?Comment:For this application slopes 5-15 degrees were considered moderately productive. |
Critical slope cut-off for very productive land ?Comment:For this application slopes <5 degrees were considered very productive. |
Nitrogen export coefficient ?Comment:Water quality models within LUCI use an enhanced, spatially representative export co-efficient (EC) approach to model total nitrogen (TN) and total phosphorus (TP) exports to water. ECs are defined as the “mass of a [contaminant] per unit area per unit time and quantified in kg ha−1 yr−1. LUCI spatially positions ECs in association with land cover categories at the DEM scale (5 m2). Here, ECs for pastoral land cover are calculated by LUCI using algorithms derived from a large ( > 14 000 samples), pastorally based national dataset. The dataset consists of detailed farm nutrient input and management variables that have been entered and run using OVERSEER® to generate nutrient loss predictions, which are also included in the dataset. This variable is based on the class variable Land use land cover. |
Phosphorus export coefficient ?Comment:Water quality models within LUCI use an enhanced, spatially representative export co-efficient (EC) approach to model total nitrogen (TN) and total phosphorus (TP) exports to water. ECs are defined as the “mass of a [contaminant] per unit area per unit time and quantified in kg ha−1 yr−1. LUCI spatially positions ECs in association with land cover categories at the DEM scale (5 m2), and consider slope. Here, ECs for pastoral land cover are calculated by LUCI using algorithms derived from a large ( > 14 000 samples), pastorally based national dataset. The dataset consists of detailed farm nutrient input and management variables that have been entered and run using OVERSEER® to generate nutrient loss predictions, which are also included in the dataset. This variable is a constant based on the class variable Land use land cover. |
Soil drainage ?Comment:Soil drainage is determined using variables from soil data, and is constant with respect to soil data classes. Slope and aspect further inform soil drainage values. |
Soil fertility ?Comment:Soil fertility is determined using variables from soil data, and is constant with respect to soil data classes. Slope and aspect further inform soil fertility values. |
