Hey, cabby! How much to take me to the station?
"Five bucks, sir."
"And how much for my suitcase?"
"No charge for the suitcase, sir."
"Okay. Take the case and I'll walk."
Hermann HellriegelDied 24 Sep 1895 at age 63 (born 21 Oct 1831).German chemist who directed agricultural research at the Bernburg experimental Station in Prussia concerned with determining optimum conditions for growing sugar beets, the primary source of sugar. He made the important discovery of the fixation of nitrogen by certain legumes which took converted nitrogen from the air into a form in the soil accessible for organic assimilation by plants. He identified that it was due to the symbiotic action of soil bacteria in nodules on the roots of the legumes. This improvement of the soil provided particular advantage in the annual rotation of grain crops (which used up nitrogen in the soil) with legumes like beans, peas and clover (which restored nitrogen to the soil).« |
