Stavropol Kray is situated in the South of the European part of Russia mainly in steppe and semi-desert zones. 5,8 mln ha (more than 80% of total region area) are covered by agricultural lands, and 4 mln ha of them are arable lands, 2,1 mln ha are under cereals (main crop is winter wheat). Gross grain harvest in Stavropol kray in average is about 7 mln tons, and grain yield is 3,3 ton/ha.

Stavropol test site has S=66000 sq. km. It was organised in 2014 by the Stavropol Research Institute of Agriculture and Space Research Institute to conduct researches aimed to develop remote sensing methods for annual land use and crop types mapping and yield assessment at the regional level.

The site consists of two levels: regional (Stavropol kray) and local (experimental fields), which are different in functional assignment and frequency of measurement of biophysical and chemical parameters.

  • Regional level corresponds to entire Stavropol kray and focused on satellite data based land use and crop types mapping R&D component;
  • Local level corresponds to set of experimental fields and focused on crops biophysical parameters assessment R&D component.

Typical Field Size (Area): 30 - 130 ha

Crop Types: winter wheat, spring/winter barley, peas, soybean, sunflower, winter rapeseed, perennial grasses

Typical Crop Rotation: fallow/peas – winter wheat – winter rapeseed - winter wheat

Crop Calendar: September-July - winter crops; April-October - spring and summer crops

Climatic Zone: Unsustainable moisturizing with a temperate-continental type of climate.

Annual temperature: 9.6 °C

Annual precipitation: 560mm

Soil Texture: 2 soil zones: chestnut soils (3.54 mln ha) and chernozems  (3.15 mln ha).

Topography: The landscape is mostly flat with slopes ranging from 0% to 2%; and near 15% of the territory is hilly with slopes from more than 2%. So potential risk of wind (95%) and water (82%) erosion is high; joint manifestation of both types of erosion is effected more than 77% of kray territory.

Soils: Dominant soils are chestnut soils (3.54 mln ha) and chernozems (3.15 mln ha). Large areas are affected by salinity of various degrees with chloride-sulphate, sulphate and sulphate-chloride type of salinity.

Drainage class/irrigation: Soil drainage is ranging from poor to well drained.

Other Site Specifications: High potential risk of wind (95%) and water (82%) erosion; joint manifestation of both types of erosion is 77% of kray territory. Large areas in Stavropol kray are affected by salinity of various degrees with chloride-sulphate, sulphate and sulphate-chloride type of salinity.

Agricultural methods used: Crop types are spring/winter wheat, spring/winter barley, peas, soybean, sunflower, winter rapeseed, perennial grasses. Typical crop rotation is: fallow/peas – winter wheat – winter rapeseed - winter wheat. Farming methods are no-till and tillage-based.
