Dear all

I am working on maize crop simulation modeling in relation to soil
depths, nitrogen dosage. In my research i have followed Alkaline
permanganate method for the analysis of soil NH4 and NO3, but in
DSSAT manual this method is not followed. Please suggest whether
my nitrogen values are valid or should I necessarily follow the
methods listed in DSSAT.
waiting for quick reply.
