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 Effect of Fertilizers on the Physical Properties of Hawaiian Soils It has been the custom in Hawaii since agriculture was first placed upon a commercial basis to stimulate crops with heavy applications of mineral fertilizers. This procedure has been maintained in spite of the fact that a majority of the soils are naturally well supplied with plant food, in some instances abnormally so.

Book Description
Excerpt from Physical Properties of Hawaii Soils, With Special Reference to the Colloidal Fraction The origin, formation, and composition Of tropical Hawaii soils invest them with physical and chemical properties which vary widely and are quite unlike those Of the soils Of the mainland Of the United States. In some cases they also differ considerably from those Of Soils Of other tropical countries. The large amounts Of fine material, organic and Inorganic, with a chemical composition typical Of lateritic decomposition, cause condi tions which are radically different from those Of other Soils and which are sometimes extreme in nature, Moisture relationships especially exhibit unusual behavior In many Of the soils. It has long been known that the colloidal fraction Of the soil plays a significant role In the soil complex phenomena. The investigations Of the past decade have definitely established the fact that practically all the essential properties Of soils are directly or indirectly linked with the Colloidal phase, and that such important processes as flocculation, drainage, plasticity, moisture holding capacity, shrinkage, fixation and availability Of plant food elements, hydrogen Ion concentration, and base exchange are functions Of the colloidal part Of the soil. The soils Of Hawaii, because Of the above mentioned differences In origin, formation, and composition, may be logically expected to exhibit a difference in the nature Of the colloidal complex as com pared with Soils of other countries.

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 Composition of Hawaiian Soil Particles One of the primary characteristics of Hawaiian soils is the wide diversity of types which makes difficult their classification according to the usual methods employed in soil surveys. A wide variation in chemical composition, as well as in physical properties, is found within very Short distances. During a recent investigation in this laboratory upon the determination of humus, the character of the clay in Hawaiian soils, as regards certain of its properties, was found to be radically different from that in mainland soils. Chief among these abnormal properties is the incomplete coagulation when coag ulants are added. This is especially true in case of addition of ammonium carbonate, which has been successfully used on mainland soils for the coagulation of clay in humus extracts. This peculiarity of the clay has led to a study of the composition of the coagulable and noncoagulable grains and a further investiga tion upon the composition of the clay, fine silt, silt, fine sand, and coarse sand separates in the important Hawaiian types of soil differ ing in color, chemical composition, and physical properties.
