Gravimetric devices and techniques tested were the laboratory oven, gas stove and fry pan, standard microwave oven, battery-powered field microwave oven, and moisture analyzer. Electrical devices tested were the electrical density gauge, and the soil density gauge.
14 wrz 2022 · The availability of soil moisture is a function of soil density, soil texture, soil structure, meteorological and climatic factors, soil organisms, and soil–plant–atmosphere interactions . Soil water content measures the amount of water in soil pore space.
26 lis 2020 · This study focuses on assessing the applicability and precision of the halogen moisture analyzers versus the conventional laboratory ovens to obtain the soil moisture content.
This laboratory test is performed to determine the relationship between the moisture content and the dry density of soil for a specified compaction energy. Compaction energy is the amount of mechanical energy that is applied to the soil mass.
The moisture content of a sample of soil is obtained by measuring the change in the mass of a sample of the soil prior to and after drying to a saturated surface dry condition over a heat source in an open pan.
Grain size analysis is a typical laboratory test conducted in the soil mechanics field. The purpose of the analysis is to derive the particle size distribution of soils. The analysis is conducted via two techniques.
Sieve analysis is a method that is used to determine the grain size distribution of soils that are greater than 0.075 mm in diameter. It is usually performed for sand and gravel but cannot be used as the sole method for determining the grain size distribution of finer soil.
