### Re: Fertilizer apply

Hi david! I was trying to extend a bit the simulation so that I had more days after the fertilization apply so I could post it here as you asked me. But, after getting the graphs I told you, I made a change in the simulation (related to soil dry density property, which I set it by layers instead of ...

### Re: Fertilizer apply

Hello david! Ok, so I see how you calculate the nitrate in the cells, just one thing to do it right, as the vegetation output is daily, things like water content and so, you just obtain an average value for the day, right? Now, I am applying 1000 kg of a fertilizer that has a fraction of N of 0.15 a...

### Re: Properties

thanks david! both definitions are in the wiki, in porousmediaproperties (one in the keywords square and the other in sample square). ok, so you say that in my case it wont improve a lot cause i´m only running with one property, but the case is,l that (and related to the other post of fertilizer app...

### Re: Properties

Hi again! :) I´ve seen different explanations for the keyword NEW_FORMULATION. They are: 1) NEW_FORMULATION : 1 !1 - do not use moduleadvectiondiffusion (removed advection computation); 0 - old formulation. 2) NEW_FORMULATION : 0 !if 1 then spatial methods will be the same for all properties. Maybe ...

### Properties

Hello all, I write here several doubts I have inside the properties modules, please if you can give me a hand with this, First, I see that there is the possibility of selecting the way of discretization of the advection and diffusion. It can be distinguished between explicit and implicit. What is ea...

### Re: Roots depth

Hello!! With the change made, the roots depth fits to the maximum of the growth database, but now, I find that the flow in the rivers change a lot, specially the baseflow. I attach a screencap ( the blue line is the simulation made with old exe). Is this due to executable? maybe new keywords? thanks!!

### Re: Roots depth

Nothing.. I changed conductivityface to 1,2, 3 and 5, but nothing..
thanks!

The error came with the exe file, cause I´ve tried running the simulation with previous executable and no problem!

### Re: Roots depth

yes yes, the only thing I changed was the executable david sent me to fix the problem with roots depth. here goes the porous media! :) START_WITH_FIELD : 1 OUTPUT_TIME : 0 864000 THETA_HYDRO_COEF : 0.995 CUT_OFF_THETA_HIGH : 1e-15 CUT_OFF_THETA_LOW : 1e-15 HORIZONTAL_K_FACTOR : 5.0 THETA_TOLERANCE :...

### Re: Roots depth

Hi!!
I lowered the value of the rain_dt to 10sec (I was using 3600) but nothing. Then, I tried with the keyword conductivity_faces (I had set it to 3) but I changed it just in case to values 1, 2 and 5, but nothing..
same message about iterations

### Re: Roots depth

I´ve tried running with the executable you sent me, and after getting an error related to: OVERLAND_CHANNEL_INTERACTION_METHOD keyword is deprecated. Use CHANNEL_LINK_METHOD instead. ReadDataFile - ModuleRunOff - ERR366 I changed the method to second and newer keyword, and it started running but bI ...
