On Fervorization of Plant Nutrient Substrata

Sažetak

We are now at the end of our treatise. From the results of our experiments many questions have arisen, impossible to answer for the time being. In the following some of them we will only just touch. In any case Radermacher and Kids (19) believe, that a new line of investigations has been established. As a matter of fact there exists already an extensive literature on the benefit of heating of soils— the so- called soil sterilization- and the results of those investigations have already heen put into practise. We state, however, that the cause of the amelioration of the soil was not clear hitherto. It has been shown by our experiment with nutrient-solutions, that this amelioration is not merely the result of sterilization, but also of general changes in the state of the nutrient subtratum, caused by heating. To bring this: effect to the fore we proposed the term »fervorization«.
Heat sterilization is neither equivalent to chemical sterilization nor to sterilization by freezing. The results of the micro-biological cultures in moist soil sterilized by heat must be judged with caution, for they include not only the normal growth of the cultures but also the growth influenced by fervorization. Therefore it seems important to compare cultures on substrata, sterilized by chemicals, by freezing and by heat.
We are quite alive to the fact that the investigations which we have described must be supplemented in many ways. Nutrient substrata and salts will have to be examined on their behaviour in connection with a far greater variety of plants.
Abowe all it will be neccessary to throw more light upon the changes caused by the fervorization of water. We consider the investigation of this problem a task for chemists and physicists, whereas for physiologists it is of interest to examine whether fervorized water exercises influence on other phenomena of life.
Finally, it should be remembered that fervorization possibly takes place under natural circumstances. The great fertility of the otherwise poor soil in the tropics may be partly due to the fervorization of the soil caused by the radiation of rays by the sun. There may be similar conditions in other climates.
