4. Reduction of water in agriculture soil also can
be through evaporation and evapotranspiration
process. Moisture gauge is useful technique to
investigate reduction of water due to this factor.
Covering large area of agriculture soil using plas-
tics will be effectives and straw will be used for
localised control of evaporations.

5. Control density of embankments involved inves-
tigation of sediment density and concentration in
situ using moisture gauge technique. The rela-
tion of moisture content with crops rotation is in-
fluenced by bulk density of compaction of soil as
measured using neutron moisture gauge.

Variations in the water storage capacity of soils and
successive moisture profiles can be measured and then
integrated between the surface and the depth at which
no change occurred in the water content. This ap-
proach provides information of variation in the water-
storage capacity of the soil was directly.

2.7.1 Application in Civil Engineering

Moisture in soil in civil construction area is important
property to ensure building structure or road could main-
tain their strength. Traditional method to measure mois-
ture in soil is by drying the soil in the oven and measure
the weight, assuming the weight of water will reduced
