Regarding use of season data

Sir,
I have one season data of water and nutrient distribution in soil. Can I use first half data for model calibration and second half data for validation? Please guide me and if it can be done then please tell me reference of the paper if any.
Thanks

Dear Friends I am simulating the Phosphorus (P), potassium (K) and sulphur (S) movement in the soil under drip fertigation. I could able to run the model for potassium and phosphorus but I could not run the model for Sulphur movement. I got the Kd values for P and K from the paper suggested by Jirka...

Movement of concentration

Hello everyone, I am simulating phosphorus movement under drip fertigation. I am applying the specific quantity of fertilizer. I did the chemical analysis of soil samples at different depths, i found that Phosphorus is moving upto 6o cm even beyond that depth. I am giving all the soil hydraulic prop...
