How to turn cobblestone and sand into dirt in FTB Mindcrack

I have a compressed plantball machine that makes compressed plantbals from dirt but i don't have a lot of dirt left and i was wondering if i could make dirt from either couble and sand or both to get me more dirt.

I would prefer using buildcraft and industrialcraft items/blocks only but if that can't be done with those i can still switch.

Is this possible and how?

PS. I have all EU that you will need, don't worry about power usage!
