Simulating year-round pasture vegetation cover with multiple plant species?

[M Arms]

Hi all,

After I finish the weather set-up in my SWAT+ project I move on to simulating the land management practices that farmers are currently doing on their land. 

One of these farmer is using regenerative planting (with seed mixes of up to 15 species) in their pastures to have constant and diverse vegetation cover throughout the year. I am still relatively new to SWAT+ so I do not know how to go about this in SWAT+ Editor. Does anyone have any recommendations or resources for understanding how to do this?

Thanks,

Maggie
