Annual average temperature in °C. If not known write -9999. Only numbers may be entered in this field.

Annual rainfall in mm. If not known write -9999. Only numbers may be entered in this field.

The climatic water balance (CWB) is defined as the difference between precipitation depth and the depth of potential evapotranspiration at a given site during a certain time period. Climatic water balance in mm. If not known write -9999. Only numbers may be entered in this field. Please use dot (.) for decimals, not comma.

Reference crop evapotranspiration or reference evapotranspiration, denoted as ETo. The reference surface is a hypothetical grass reference crop with an assumed crop height of 0.12 m, a fixed surface resistance of 70 s m-1 and an albedo of 0.23. Reference evapotranspiration ET0 in mm. If not known write -9999. Only numbers may be entered in this field.

Enter carbon to nitrogen (C:N) ratio (dimensionless). Only numbers may be entered in this field.

Field capacity expressed in mm of water in the soil profile. Only numbers may be entered in this field.

Soil depth is defined as the unconsolidated material immediate the surface of the earth serves as natural medium for the growing plants. Soil depth defines the root space and the volume of soil from where the plants fulfil their water and nutrient demands. Enter soil depth in cm. If not known, write -9999. Only numbers may be entered in this field.

Select the drainage class that best describes the field.

Enter soil organic matter percentage. Soil organic matter is any material produced originally by living organisms (plant or animal) that is returned to the soil and goes through the decomposition process. Please use dot (.) for decimals, not comma. Only numbers may be entered in this field.

Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Most soils have pH values between 3.5 and 10. Enter soil pH as a numeric value (e.g. 6.5). Only numbers may be entered in this field.

Soil skeleton, also known as rock fragments is the fraction>2 mm. Enter percentage of coarse fragments (skeleton) in soil. Only numbers may be entered in this field.

Select the dominant soil texture class. Coarse: particles with diameter larger than 0.075mm (sand, gravel, cobbles). Medium (Loam): 50% or less of silt and sand. Fine: more than 40% clay.

Enter total nitrogen in soil as percentage. Only numbers may be entered in this field.
