Book Description
Excerpt from The Chemistry of Steam-Heated Soils The subject of the effect which heat has upon soils 13 rather promi nently before agricultural investigators at the present time. This subject has received Increasing attention during the last decade, par ticularly from the point of view of sterilization and partial steri lization. There has been much valuable information obtained along the biological lines concerned; also much speculation in this regard without due consideration of the chemical and physical changes in volved, owing largely to the fact that these were not known or but imperfectly understood. The biological factors can not and should not be ignored, but it must be remembered that they are only of sig nificance or interest in the light Of the biochemical changes which they produce in the soil. Moreover, any biochemical changes produced in the soil through other means, be they cultural or by the addition of manures and fertilizers or by the influence of steam heating, in turn affect-the biological activities. The chemistry, therefore, of the soil both before and after heating in, sterilization work becomes of the greatest significance to the biological worker.

Book Description
Excerpt from The Effect of Heat on Hawaiian Soils While the Old system of burning the soil has gradually fallen out Of use, the closely related partial sterilization by means Of heat and vola tile antiseptics is of great interest at the present time. In greenhouse work steam sterilization finds extensive application and has been the subject of interesting investigations during the past few years. Likewise the action of dry heat in its relation to partial sterilization and in comparison with the effects Of volatile antiseptics on subse quent biological activities has received considerable study. The Old idea of considering the subject in a restricted physical and limited chemical sense is, therefore, giving way to a broader view of the question. The more specific chemical effects involved, including cer tain physico-chemical effects dealt with more In detail in this paper, and the biological results are now being studied.

Book Description
Excerpt from Heat Transference in Soils The investigators in this line of work have been interested mainly in ascertaining the temperature of the soil at given depths during the growing season. Some have tried the effect of various top dressings manure admixtures, mulches, rolling, etc. - upon the soil temperature, and many of these results are valuable and reliable since they were gotten under comparable though undetermined conditions. Others, too, have recognized the part which the total quantity of available heat plays in the development of plants, and attempts to measure this heat have been made by integrating the air temperatures close to the ground and integrating the sunshine. Such calculations are also Supplemented by an integration of the heat gained by the soil from day to day as the season progresses.

Book Description
Excerpt from Some Effects of Steam Sterilization on Physical, Chemical and Biological Relationships of Soils The study of the complicated inter-relationships of soil micro-organisms (9) and plant diseases, and of soil micro-organisms and soil fertility, may be simplified by first studying the relationships of a few known organisms on sterilized soil devoid of its enormous population.
