Environmental site for the collection of soil samples

Geographic position, elevation, and locality	Zone/ecosystem and soil source type	Physical and chemical characteristics of the soils
Dumping plot Suzak A and B: N 40° 59.625′, E 72° 53.796′ 1136 m elevation above sea level; Jalalabad province, Suzak region The dumping plot has an area of about 0.9 ha. It has free access and contains nine separate tranches with a total of 2000–3000 t of pesticides dumped.	The plot is located on the bank of the Kougart River, in the northeastern part of the Fergana Valley. Light sierozem soils: These soil types are formed by vegetation from the ephemeral desert steppes. Parent rocks are loess-like loams. The climate of this zone is continental. In summer, the air temperature can reach up to 43 °С, and in winter down to 25 °С.	Mechanical composition is silt-loam, sandy loam, and loamy loess. Humus content 0.7–1.7% Total nitrogen 0.1–0.14% The soils are calcareous at the surface: CO2 in the upper layer is about 2–3% Mechanical fraction, %: 1.0–0.25 mm; 5,34%; 0.25–0.05 mm: 17.5%; 0.05–0.01 mm: 47.73%; 0.01–0.005 mm; 13.7% 0.005–0.001 mm: 12.97%; <0.001 mm 5.32% Soil pH: 8.0 The values of EC indicated that all samples of the soils are non-saline.
Dumping plot Balykchy N 42° 28′, E 76° 11′ 1900 m elevation above sea level; Issyk-Kul province A former pesticide storage location is located in Balykchy city. Seven or more barrels of liquid pesticide are stored in the crumbling buildings, in poor storage conditions.	The plot is located 300 m from the Issyk-Kul Lake. There is a residential area within 200 m of this site, and livestock are sometimes grazed here. Mountain/valley gray-brown desert rocky soils: These soil types are formed under extreme continental desert climate conditions. The surface is composed of rocky and gravelly soils. The climate is dry; rainfall varies within 100–250 mm. The weather here is dominated by constant winds.	Humus content 0.5–1.5% Total nitrogen 0.1–0.14% Mechanical fraction, %: 1.0–0.25 mm: 5.34%; 0.25–0.05 mm: 17.5%; 0.05–0.01 mm: 47.73%; 0.01–0.005 mm: 13.73%; 0.005–0.001 mm: 12.97%; <0.001 mm: 5.32%; 0.001 mm: Soil pH: 7.6 The values of EC indicated that all samples of the soils are non-saline.
