fertilizer

Carbon nanotubes have improved existing technologies in fields ranging from electrical circuitry to architecture to materials science. So is it any surprise that when researchers in Arkansas applied the miraculous microscopic structures to tomato seeds, the plants grew faster, stronger, and more plentifully?

You say tomayto, I say tomahto.

You say Miracle-Gro, I say ... pee.

Apparently, human urine works remarkably well as a fertilizer for tomatoes, according to a new study out of Finland.

Plants fertilized with a mixture of stored human urine and wood ash produced 4.2 times more fruit than plants without the pee, the study found. The urine-fertilized tomatoes had more beta-carotene than unfertilized ones, and much more protein than traditionally fertilized plants.
