Chemical Properties of Eroded Soil Material

Journal of Agronomy and Crop Science, 2002
AbstractIn a 5‐year stationary investigation at an experimental station in central Croatia, total amounts of erosional drift were measured on a Stagnic Luvisol on which six tillage methods were used. The chemical properties of the tilled soil and the erosional drift were recorded for each trial method in the same plots. A generally higher soil reaction

The Soil. Physical, Chemical and Biological Properties

2016
This chapter provides a basic description of soil properties and processes, stressing the concept that the soil is a dynamic entity where complex interactions among its biological, chemical and physical components take place. All these components and properties determine the functioning of the soil for different purposes; this functioning is included ...

Physical and Chemical Properties of Soil Aggregates in a Brunizem Soil

Soil Science Society of America Journal, 1958
Abstract A surface sample of Sharpsburg silty clay loam was separated into aggregate fractions of diameters 4760 to 2380µ, 2380 to 1190µ, + … +, 37 to 18.5µ by means of rotary sieves and elutriators. A similar separation was made for primary particles. Each fraction of aggregates was analyzed for chemical and physical properties.

Erosion and Soil Chemical Properties

2018
Soil erosion by water involves complex interactions between rainwater and soil, as influenced by soil properties and soil condition at the time of interaction. Depending on the constituents making up the soil and their relative proportions, soils may behave differently than rainfall and have different amounts of runoff and erosion.

Microbiological and chemical properties of paddy soil

Plant and Soil, 1967
Rice is one of the main crops in the U.A.R. especially in fertile soils. Cultivation of rice in such soils is expected to change the normal microflora ; a matter which may affect their fertility. It is expected that water-logging will promote the growth of anaerobic microflora.

The Chemical Properties of Soil

1964
Humus 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 Effects of Palygorskite on Chemical and Physico-Chemical Properties of Soils

2011
Abstract The present review is intended to summarize studies on the effects of palygorskite on chemical and physico-chemical properties of soils carried out in recent years, and to discuss future research required in this area. When palygorskite-containing soils are involved in irrigation practices, release of Mg from palygorskite into the soil ...

Chemical Properties of Soil

2012
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.

Sampling Soils for Physical and Chemical Properties

Soil Science Society of America Journal, 1956
Abstract A sampling study was made on soil characteristics from an organic matter experiment on Sassafras sandy loam soil on Long Island. The paper gives the components of variance for plots, samples, and determinations for several chemical and physical properties.

Physico-Chemical Properties of Soils: Soil-Water Systems

Journal of the Soil Mechanics and Foundations Division, 1959
The 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.
