In the course of the current agrarian reform in Russia a lot
of private (peasant) farms appeared, their total number
being now about 280,000. Their contribution to the
agricultural production, especially in grain production, is
not large for the moment. However, in some branches, as
for example in potatoes and vegetables production, it
becomes significant. About 10 min.ha of the agricultural
land, including more than 7 min.ha of arable land, belongs
now to private farms and the area is increasing. The
average size of private farms is about 50 ha, among them
more than 90% is agricultural land and 70% is arable land.
Agricultural land of all users in Russia makes up 220
min.ha. The structure of agricultural land use is given in
Table 2. Among the agricultural land arable land occupies
about 130 min.ha (60%). The remainder is mostly under
hayfields and pastures (37%). The main component in the
agricultural production is cereals production. It occupies an
area of 56 min ha, i.e. about 44% of the total arable land.
The main crops for cereal production are wheat, barley, rye
and oats. Most of the area (more than 75%) is occupied by
spring cereals. Winter wheat areas are only 13% of all
cereals land, but they are very important due to their
contribution to the grain production (more than 25%).

4. KURSK TEST AREA
The Kursk region is situated in the central part of the
Middle-Russian Hills and by its natural conditions it
belongs to the subzone of the northern forest-steppe with
typical and leached chernozems.
Two natural/agricultural zones are distinguished according
to the complex of natural factors on the territory of the
Kursk region:
the first is a north-west one: forest-steppe, hilly,
loamy, with gray forest soils;
the second is a south-east one: forest-steppe, hilly,
loamy, with prevailed leached and typical
chernozems. |
The Kursk test site (Medvensky rayon) is situated in the
“second zone. The site belongs to the arid territory according
to conditions of humidity. Annual rainfall is about 500-600
mm, and in the period of active vegetation growth it is
about 260-310 mm. Most rainfall is during the first half of
the summer with often heavy showers. During the
vegetation period, winter wheat needs about 330 mm water,
spring wheat needs about 335-360 mm. Actual water
resources (including soil moisture supply) make up 270-
360 mm and provide water demand for 85-1004.
The land surface of the Kursk region is about 3 min.ha. The
Kursk region is situated in the Central Chernozem
economic region of Russia, which is favourable for cereal
cultivation due to soil and climatic conditions. The
biological productivity is rather high, and the territory is
well cultivated.
Agricultural lands occupy about 80% of the region
territory, arable lands being among them also about 80%.
The cereals occupy about half of the arable land, and
usually about 25-30% of the area is under winter crops.
Winter wheat (19-20%) and spring barley (14-16%)
prevail. Most of the territory belongs to big collective
farms, characterized by a rather large field size (75-150 ha).
Due to agrarian reform a lot of private farms appeared in
recent years. The hectarage of such private farms is on
average 50 ha, covering together 116 ths.ha in the region at
the moment, 75 ths.ha of which are being cultivated.
A specific feature of the territory are the rather widespread
erosion processes. The area of eroded agricultural land and
gullies in the territory of the test site is about 740 ths.ha. A
high degree of eroded dissection (1.2-1.6 km/km2) is found
in the northern part. In addition, some biospheric reserves
with typical steppe grasslands are situated in the territory.
5. PRELIMINARY RESULTS
5.1 Land Cover Classification at Level 1 (Continental)
When studying the RIVM 10 Minutes pan-European Land
Use data base for the region around Moscow and
southwards passing Kursk, it can be observed that arable
land is the dominant land cover type. Moreover, the RIVM
database is largely based on statistical data which have a
low geographic accuracy. So, this information is not
detailed and not accurate enough for monitoring
agricultural land use in Russia.
The same conclusion can be drawn for the PELCOM base
(reference) map, although forested areas are mapped much
better because of the including of the ESA Digital Forest
Map of Europe (Fig. 2).
