Abstract:
The land suitability for cherries orchard represent the extent to which soil satisfy requirements of Cherry trees, on the
local climatically conditions and within the framework of a management adapted to adapted to this species. Land with
optimal suitability for cherry plantations are located in areas with average annual temperatures of 20 years, 8 ÷ 11°C,
the average temperature of May are between 14 and 16°C, the absolute minimum annual air temperature does not drop
abruptly as -20°C), and if it decreases gradually does not fall below (-28°C). In Romania, cherry trees grow well on a
wide range of soil types such as Chromic Luvisols, Phaeozems, Eutric Cambisols, Chernozems and even Kastanozems.
The stagnic, gleyic and stagni-gleyic soils are unsuitible for cherry plantations due to poor drainage. Another optimal
soil characteristics for cherry orchard are: pH values between 5,5-7,2, aeration porozity of 16-22%, calcium carbonate
content lower than 7%. The hyposalic, hyposodic and vertic soils are excluded from the establishment of orchards. We
intend to present a case study of Comarna catchment area. The land of this watershed has good suitability for cherries
orchard due to local microclimate, good external and internal drainage, ensured by middle slope and middle soil texture.
The specific local microclimate is reflected by an earlier ripening cherry, about two weeks compared to neighboring
basins located on the same altitude. Some of the lands are degraded by landslides and have severe restrictions for the
establishment of orchards. The soil are more colder due to high content of clay, high water capacity and land shaded
exhibition.
