Determination of the hydrogen ion concentration (pH) of soil.
- Thu, 02 Jul 20 PM
The soil pH is defined as the negative logarithm of the hydrogen ion activity. Mathematically, it is expressed as: pH=-Log[H+] and it ranges from 3 to 9,
Determination of The Moisture Content of Given Soil.
- Thu, 02 Jul 20 PM
Soil moisture determination is of major significance. Soil moisture influences crop growth not only by affecting nutrient availability, but also nutrient transf
Determination of Total nitrogen in given soil sample (Kjeldahl Digestion Method)
- Fri, 03 Jul 20 PM
Kjeldahl procedure involves digestion and distillation. When soil is heated with sulfuric acid and catalyst mixture, organic N is digested to Ammonium-N. Then t
Determination of the bulk density of given soil.
- Tue, 07 Jul 20 AM
Density is defined as mass per unit volume. Soil bulk density of a sample is the ratio of the mass of solids to the total or bulk volume.
Determination of the water holding capacity of given soil.
- Tue, 07 Jul 20 AM
The water-holding capacity (WHC) is defined as the amount of water held in the soil after the excess gravitational water has drained away and after the rate of
Determination of specific gravity of a given soil
- Tue, 07 Jul 20 PM
The specific gravity of a solid substance is the ratio of the weight of a given volume of material to the weight of an equal volume of water (at 20°C).
