18-24 CONSIDERAłII PRIVIND INFLUENłA IRIGAłIEI ASUPRA CRUSTEI SOLULUI

CONSIDERATIONS REGARDING THE IMPACT OF
IRRIGATION UPON SOIL CRUST
The soil crust is formatted as a result of excessive humidity absorbed
by soil, which exceed its capacity of retaining water.
This leads to additional expense for the works, which provide remedy.
In conditions of irrigation these are performed after each watering. The
sprinkling watering has a more negative effect than in furrow watering. Soils do
not form this crust contain sand 60-80 %, dust 10-20 % and clay 5-10 %.
The main factor, which generates formation of crust on the cultivated
land, is the lack of soil particle formations stable in water and big amounts of
clay colloidal particles.

ASPECTS REGARDING WATER QUALITY AS AN
IMPORTANT ISSUE IN IRRIGATION
In spite of progress achieved in this field, the processes taking place in
agriculture are still under the unfavorable effect of some natural factors, their
occurrence, duration and extension in space not being preventable or entirely
removed. Irrigated agriculture has an increasingly important part in
environmental protection in the rural areas, at the global level irrigation being
tributary to supply with water of good quality. Assessment of water quality must
be performed on a regular basis. Equipment developed during the phase of
experimental model has been tested at ANIF- Territorial Branch Olt – Argeş.
Sensoristics of monitoring is made of sensors for pH, electrical conductivity at
25 0C, Na+, Cl-, turbidity. This equipment performs monitoring of water quality at
the intake, at the basic pumping station.
