Abstract:
Alkaline and alkalis soils are present in all soil provinces, but the most important areas are located in the central (Ciuluc
hills, at the border of Codri plateau) and southern (Southern Moldova Plain) part of the country. In world practice for
alkali soil improvement, the usual method is gypsum application in common with organic fertilization. In the Republic
of Moldova these amendments are missing and their purchasing requires considerable amount of money. Created
situation generates the necessity to replace gypsum with other calcium materials. Investigations were carried out on two
pilot areas. To assess the state of soil quality there were described soil profiles and taken soil samples from genetic
horizons. Within investigations on chemistry and quality indicators of surface water there were taken samples from
water bodies of the study areas.
