The injurious after-effects of sorghum
1924
Breazeale, J.F.
The results of these experiments indicate: First, that the injurious after-effect of sorghum is due to the presence of a toxic body formed during the decomposition of the stubble. Second, that this toxic body is shortly volatilized or decomposed. Third, that during the decomposition of the stubble, and while the toxic body is still in the soil, the flora that generates the carbon dioxide is, to a large extent, killed off. Fourth, that with the cessation of the evolution of carbon dioxide, a new equilibrium is established in the soil, in which the sodium zeolite exists in excess over the calcium salt. This causes a deflocculation of the soil.
