Nitrification Quotes (1 quote)
The virgin fertility of our soils, and the vast amount of unskilled labor, have been more of a curse than a blessing to agriculture. This exhaustive system for cultivation, the destruction of forests, the rapid and almost constant decomposition of organic matter, together with the problems of nitrification and denitrification, the multitudinous insects and fungus diseases which are ever increasing with marvelous rapidity year by year, make our agricultural problem one requiring more brains than of the North, East or West.
In Farmer’s Leaflet 7: The Need of Scientific Agriculture in the South (1902). Reprinted in The Review of Reviews (1902), 25, 322.

In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
