The Chemical Properties of Soil
1964Humus to the chemist is the final product of the disintegration of the organic substances of plant and animal tissues, but to the gardener and agriculturist it means a whole range of products between the raw material and humus proper. It will be convenient therefore to say something first of all about the processes that bring about this decomposition ...

The soil is a chemical entity. All the materials there are chemical substances. Soils are composed of solid, liquid, and gas; soluble and insoluble; and organic as well as inorganic substances. There are ions and compounds, salts, acids, bases, minerals, and rock fragments. There are also colloids which are very active chemically.

Physico-Chemical Properties of Soils: Soil-Water Systems
Journal of the Soil Mechanics and Foundations Division, 1959The heat of wetting, the diffusibility of hydrogen and isotopic prothium-deutrium exchange, indicate that a part of the water in a clay-water system should be considered as belonging to the mineral phase. The minerals thus consist of a central silicate skeleton with an outer part of aqueous composition.

Liming impact on soil chemical properties
2010In order to examine the residual effect of liming on soil pH and plant available phosphorus and potassium, soil samples from two field trials were analyzed. First trial was conducted in 2000 on Pleternica site where increasing rates of carbocalk (refuse from sugar factory with total Ca content 344 g kg-1) was applied (0, 15, 30, 45, 60 and 90 t ha-1 ...

Strength Properties of Chemically Solidified Soils
Journal of the Soil Mechanics and Foundations Division, 1972Injection of chemical grout is a valid means of strengthening sandy soils. Submission of valid strength data is recommended as a condition for use of any particular grout material. Pertinent data should include the specimen size, method of preparation, age, curing environment, and method of test.

Physico-Chemical Properties of Soils: Role of Soil Technology
Journal of the Soil Mechanics and Foundations Division, 1959This paper defines and describes the applied science called "soil technology." The powerful contributions that soil technology makes to soil engineering are next presented and illustrated. Some of the future developments in soil knowledge which can be expected are then discussed.

Physical, Chemical, and Mineralogical Properties of Soils
1995Soils used for constructing ponds originally occurred at or near the land surface. Some were well-drained soils, and others were situated in wetlands and covered with water all or part of the time. There are three basic types of aquaculture ponds: watershed ponds, levee ponds, and excavated ponds.1 Watershed ponds are formed by making embarkments ...

Chemical Properties of Soils for Growing Plants
1999Soil reaction is the amount of acids (acidity) or bases (alkalinity) present in a soil and is indicated by a term called “pH”. By definition, pH is the logarithm of the reciprocal of the hydrogen ion (H+) concentration, or When a number has a smaller superscript number with it, the number is raised to that power which is called the “logarithm.” Raising
