›Die Verlobung‹ »an den Ufern der Aar«, primarily the development of high yielding grains, would solve the problem. Unfortunately the grains require large amounts of nitrogen fertilizer, the price of which has soared over the years because of the cost and scarcity of the fossil fuels required for its commercial synthesis.

Denkübungen Heinrich von Kleistssults from the lack of knowledge of the ecology of the root-nodule bacteria. If the appropriate host and an effective bacterium are both present in fertile land, there ought to be active nitrogen fixation. The fact that often no such appreciable nitrogen gain is evident or the fixation is insufficie
