Re: What will happen if we water plants with coffee, milk or orange juice?

Well, I'm not an expert in botany, but I think I
can predict the outcome.  I beleive that water will be the best.
Why?  Orange juice is too acidic. It would cause the soil to be so acidic 
that it would hurt the plant.  Coffee would probably also cause the same
problem.  In addition, coffee might contain tannins, which plans use to 
kill other plants.  I know for sure that walnut trees release tannins, 
which kills most other plants underneath it.  This stops other plants that
could compete with the tree.
Milk would probably kill the plants, too.  Actually, the milk would 
probably give extra nutrients, nutrients the plant can't use, to soil 
fungi.  These fungi would likely infect the plant, causing the roots to 
rot.
Water, soaked overnight with manure, is good, but it could carry some 
diseses, so it might not be good for kidnergarten students.
