Dear all,

I got some data from a field experiment in which they tested the influence of different tillage practices on the physical, chemical and biological soil properties and also on the productivity of some crops. 
One idea came to my mind: to use a simulation model that uses as input data those physical, chemical and biological properties and theferore conclude after some simulations the implications of these different tillage practices. However, I have some problems:

1) Which simulation models are more suitable for this situation?

2) Which processes that I should consider (simulate) to have these soil properties as important parameters? 

3) Will these simulation models (or the process I am looking at) be sensitive to the physical, chemical and biological properties?    

Sorry for this quite broad question but I hope some of you can help me.

Kind regards,

Rômulo
