In Turkey, pastures account for 28% of farmland
(Türkiye…, 1978), and 20 % of them have been dis-
turbed because of irrational use and unfavorable eco-
logical conditions (Genckan et al., 1990). Pasture pro-
ductivity depends on environmental factors as well as
on the species that constitute their vegetation (Genc-
kan, 1974). Therefore, before planning the use of any
pasture, it is necessary to study speciﬁc features of its
botanical composition. The diversity of soil types in the
region accounts for the presence of different plant for-
mations in its plant cover, with the most widespread
vegetation types being forest, maquis (evergreen shrub
thickets), phrygana, steppe, meadows, and marshes.
MATERIAL AND METHODS
Studies were performed in the steppe on the Amic
Plain (Selam ﬁeld) between 1999 and 2000 (one or two
geobotanical trips per month). Plant samples were
taken from steppe associations that are widespread in
this region: Ephemeretum, Petrosimonia brachiatae–
Ephemeretum, Cressa creticae–Hordeumetum miriniu-
mae, Alhagi manniferae–Hordeumetum miriniumae,
Prosopis farctae–Hordeumetum miriniumae, Ammi
visnacae–Hordeumetum miriniumae, and Cressetum
Phytomass stock and structure by fractions (grasses,
legumes, and mixed herbs) were determined as
described (Coupland et al., 1974; Vagina and
Satochina, 1976; Titlyanova et al., 1988). Samples were
taken from 1-m
test plots ﬁve times per month and
plants were identiﬁed at the species level (Zohary,
1973; Walter, 1978; Kürschner et al., 1995).
Soil samples 0.25 m
in area and 50 cm deep were
taken in areas occupied by the above plant associations
to determine soil pH and the contents of carbonates,
exchangeable sodium, and exchangeable potassium.
RESULTS AND DISCUSSION
Data on the climate in the study region are presented
as a diagram (ﬁgure). It shows that the driest months are
July and August, with precipitation amounting to only
4.8 and 4.6 mm, respectively (Guner et al., 2000).
Accordingly, no rain was observed during our ﬁeld stud-
ies. The largest amounts of precipitation are characteris-
tic of December (165.3 mm), January (158.4 mm), Feb-
ruary (155.5 mm), and March (160.9 mm).
Soils of this region have certain speciﬁc features. Soil
samples analyzed in this study (0–50 cm) had a low humus
content (1.01–1.69%) and pH 7.56–7.71 (Table 1); the
