Tree farms

[hallowhead1]

I have a question how can i make it so that the tree farm gets refreshed with humus whenever it runs out? I have a chest full of humus but when i turn a redstone pump on to pump it the humus comes out of the machine when its full, is there a way that i can do this without losing humus?

You can use BC Logic Gates, they have a check for Soil < 25%, so it will turn on automatically when there is less than 1 stack of Humus in your tree farm.

If it's pulling humus out of the farm, then the wooden pipe may be backwards. Make sure the thick end is facing your chest. You can also use a gate to only pump humus in when it's below 50% or 25% (either a regular gate triggering a redstone engine with a redstone signal, or an autarchic gate that does its own pumping), which will prevent overflow. Also, if you're trying to pump into a full inventory, buildcraft pipes spit their contents out. You'll need to put in an overflow loop to prevent that (run some pipes back to the chest).
