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.
