Talk:Justus von Leibig

Material merged with Justus von Liebig
This is the stuff I moved into the Justus von Liebig article:


 * He is particularly known for his contributions to agricultural chemistry. Among other things he downplayed the role of humus in plant nutrition and emphasized the role of soil minerals instead.


 * The famous Leibig's barrel is a way of visualizing the principle that a plant's vitality is limited by the one essential mineral that is in the (relatively) shortest supply at the roots. The associated graphical image is of water pouring into a wooden barrel which is made up of staves (side pieces) of differing heights.  The water can rise only as high as the shortest stave (representing the limiting nutrient) before it overflows and is wasted.  This concept is a qualitative version of the principles used to determine the application of fertilizer in modern agriculture.

What remains is information already contained in the properly-title article. --Tsavage 20:15, 11 January 2006 (UTC)
