Ever got tired of killing skeletons just to feed your children? Always believed in Mob-rights too much to build a disturbingly large grinder? The solution is here: FERTILIZER. Created with nothing but energy, air, an iron catalyst and the genius of Fritz Haber the power of ammonia is yours.
recipes:
Iron catalyst Dust:
[ID][RS][ID]
[RS][ID][RS]
[ID][RS][ID]
ID=Iron Dust
RS=Redstone dust (to increase number of free electrons :D)
Iron catalyst: Smelt the Dust.
Haber-Machine:
[code=c][?][code=c]
[C][M][C]
[Fu][?][Fu]
c=cable
C=compressor (we need of the order 160 bar)
Fu=Furnace (no need to make this too expensive)
M=Machine
?=piping? not really sure anything should go here, but crafting table looks empty ;P
The process will create 32/64 (balancing was never my forté) units of artificial fertilizer per catalyst used, using medium amounts of EUs (more than basic machines, less than mass fabricators), which can be either directly used to grow wheat/trees (same as bone meal) OR....
new alternative recipe for ITNT:
[ F ][CD][ F ]
[CD][ F ][CD]
[ F ][CD][ F ]
CD=Coal Dust
F=Fertilizer

EDIT: might be better to make gunpowder out of it instead, á la CD x 3 + F = Gunpowder. More options, less hassle.
