The salinity of soil, nutritive solutions and irrigation water is an
important parameter for growers and horticulturists. Conductivity of
solutions and salinity have a close correlation.

HI 993310 its possible to measure, in a quick and simple
way, the salinity directelly in the ground as well as the conductivity
of nutritive solutions and irrigation water.
The conductivity measurement in liquids is influenced by temperature
whereas salinity of soil depends on the soil texture and its hydric
property.
SOIL SALINITY
Plants absorb nutritive elements dissolved in irrigation water. The ion
concentration of the soil solution depends on the type of soil.
Consequently, soil can be rich or poor in nutrients depending on its
chemical composition and its property in retaining water and chemical
elements. For example, clay soil retains more water than sandy soil
since it holds more cations and has a greater microporosity.
If the soil is dry, fewer ions are at plant’s disposal. This is the reason
why conductivity readings have to be considered in light of water
presence and the soil type.

SOIL PROBE
The soil probe provides a rapid response and is an easy tool to test
the salinity of soil in a variety of applications, among them:
FERTILAZATION
By measuring the salt contents in soil and substrates, before and
after the fertilization, make it possible to know the soil fertility and to
devise an appropriate fertilization plan. Consequently, the plants will
receive the right quantity of nutrients resulting in a regular and
rapid growth, greater resistance to disease and a more appealing
state manifesting their well being.
The younger plants, especially those that have just germinated, are
particularly sensitive to salinity. They require a lower quantity of
fertilizer because they utilize the reserve of nutrients in the seed. This
is true even for resistant species such as sugar beet and alfalfa.
Later on, plants can grow faster with proper fertilization, particularly
in conjunction with optimum lighting and temperature.
