Hi all...
i want to model soil organic carbon and total nitrogen. I have the measured
data for SOC and total N pool at 0-20 cm and i want to simulate it with
DSSAT model.
However, l have following questions regarding the model.
1) Does DSSAT computes soil organic carbon at all the soil layers or only
first two layers?
2) Looking at .OSC file in DSSAT it shows a number of variables like
Stable soil organic carbon at user depth (SCDD) i did not understand at
what user depth it computes and where to specify this user depth.
3) there is another variable in the .OSC file such as total soil organic
carbon. is it the organic carbon in the entire soil profile or first two
layers only?
4) If i use stable soil org carbon at certain depth ? how do i convert it
into total soil organic C.
Thanks for help
regards
nitin
