Thanks Nobuo. We incorporated the organic amendments to a depth of 20 cm but the soil cores are 30 cm in length, so I cannot assume uniform distribution throughout column and cannot use constant initial concentration. Therefore, I tried using the stepwise distribution. I used # of pulses=1. For step...

Can Stanmod be used to model this scenario?

I took undisturbed soil cores (30 cm length) from long-term field plots where organic amendments were applied annually for nine years. I used syringe pump (5 cm/day), flow cells, fraction collector, and vacuum chamber (-65 mbar) to leach nutrients and soluble salts and obtain breakthrough curves. I ...
