Function: calculateWaterSupplyBySom()
calculateWaterSupplyBySom(
params):number
Defined in: fdm-calculator/src/other/water-supply-by-som.ts:33
Calculates the change in water holding capacity for a topsoil based on change in SOM.
This function uses the continuous pedotransfer functions (PTFs) of Wösten et al. (1999) to estimate the increase in water storage (in mm) for a 30 cm depth layer given a change from an initial SOM content to a maximum achievable SOM content.

Parameters
params
The soil texture and SOM parameters.
Returns
number
The change in water supply in mm for a 30 cm depth layer.
