SOILNDB

Page reviewed:  15/06/2025

SOILNDB is a simulation model for calculating nitrogen leaching from arable land to surface waters. The model can also be used to study the effects on nitrogen leaching from land use changes or changes in production conditions in agriculture.

SOILNDB is based on two frequently used scientific models, SOIL and SOILN, where first describe the water and energy flows, and the second nitrogen transformation and transport processes in the soil.

The SOILNDB model produces results either on an annual average or daily resolution. The model is driven by daily climatic data, mean run off and information about the soil properties and the cultivation (crops, fertilization, yield, ploughing etc.). SOILNDB is included in the NLeCCS system.
