Topography. Belarus is predominantly lowland - flat plains occupy 60 percent of the territory, plateaux 10 percent, and highland hilly areas nearly 30 percent. The north-west has broken and highland relief, while in the south-eastern part the land is mainly level. The south of the Republic is occupied by vast areas of Belarusian Polesje (wood land) which is a large waterlogged flat depression stretching for 450 km from the river Bug to the Dniepr. The relief of Belarus is divided into 4 regions: I. Belarusian lake-land occupies the northern part. Altitudes are 120-160 m. The relief consists of an alternation of hills and bottomlands with relatively colder humid climate and loamy bouldery soils. There are nearly three thousand lakes in the region including the largest, Narotch. II. The central region of Belarus glacial hills and ridges in the central part of the republic. The greatest heights of Belarus are here (Mt. Lysaja - 242 m, Mt. Dzerzhinskaja - 345 m). The region also contains the watershed of the Chernomorsk and Baltic basin. Sandy - loam soils dominate. III. The region of plains and bottomlands of Predpolesje occupies an intermediate position between the hills of the centre and the bottom land of Polesje. General height is 160-190 m and the relief is made up of typical river valleys. IV. The regions of the Polesje bottomlands occupy the southern lower part of Belarus with flattest plain, waterlogged relief and sandy peat soils. The hydrographic network involves the Black Sea and the Baltic Sea basins. The main watershed stretches from north-east to south-west along the Minsk highland. Water systems of the Western Dvina, the Nieman and the Western Bug (42 per cent of the republic’s territory) belong to the Baltic basin, while those of the Dnieper (58 per cent) belong to the Black Sea basin. The river network is dense, 0.44 km of river/km2. There are 20,800 rivers. Large rivers, more than 500 km long, are the Dnieper, the Western Dvina, the Nieman, the Prypyat, the Soge, and the Beresina. The Dnieper basin occupies the north and south and its territory in the republic is 105,000 km2. The Western Dvina basin takes up the northern part of the republic with an area of 33,200 km2 . The Nieman basin in the west has an area of 35,000 km2. Belarus has more than 10,000,000 lakes, most of them small; the largest is Naratch (with a surface area of 79,600 km2). Soils. The soils of the Republic are divided into: - auto amorphic soils (not swampy with normal moistening) which are typical of hilly relief and are the main areas that are constantly cultivated by ploughing (52.3 percent of Belarus); - semi hydromorphic soils (swampy, partly waterlogged) typical of low relief lands (i.e. lowlands that are wet in certain periods of the year, such as early spring and after very heavy rainfall) and are occupied by forests mainly (27 percent); - hydromorphic soils (peat-boggy, constantly water-logged - 20.1 percent of Belarus). Sward-podzolic soils dominate in Belarus, comprising nearly 67 percent of all types of soils. Sward-podzolic soils of normal moistening occupy 33 percent of agricultural lands, while sward-podzolic waterlogged soils occupy 33.8 percent of agricultural lands. Sward-podzolic soils have a light mechanical composition. This can be seen in the example of arable soils in Table 4.
Peat-podzolic soil predominates and makes up nearly 68 percent of all soils. Peat-boggy soils are widespread in Belarus; high-moor peat soils predominate in the north of the Republic, and lowland peat in the central and southern part of the Republic (Table 5)
The area of soils of the independent type-bogs is given in table 6.
All agricultural lands in the Republic are estimated according to fertility on the grounds of the dominant soil type (Table 7).
Land reclamation. The most important human intervention that has changed the structure of land use in Belarus in the last fifty years has been the large-scale reclamation. Drainage was carried out on 3,221,600 ha (15.5 percent of the country’s area) of which 2,927,100 ha were agricultural land (31 percent of their total area). Of the 2,927,100 ha some 1,326,800 ha were arable or ploughed land, and 1,600,300 ha of the drained lands were under hay and pasture (Table 8).
The largest tracts of drained agricultural lands are in Polesje (Brest, Gomel, Minsk region) where they occupy 40-70 percent of the total agricultural land. There are 684,100 hectares of drained agricultural lands in Brest region the difference between this figure and the total of 687,900 ha in Table 8 is due to some land having been put out of use because of non-functioning drainage systems, but these differences for all regions are small, (46 percent of the agricultural lands of the region), 529,800 hectares - in Gomel region (36 percent), 596,600 hectares - in Minsk region (31 percent), 522,300 hectares - in Vitebsk region (30 percent), 293,100 hectares - in Grodno region (22 percent), 294,400 hectares in Mogiljov region (20 percent). Recently, drainage has been designed with dual - side water regulation (drainage and irrigation). It enables the optimum water - air regime to be maintained during the growing period. The first stages included only drainage, which is why a large area under reclamation was over-drained and now needs irrigation. The areas of lands under irrigation are given in Table 9.
Half of the land in Belarus is highly acid and needs liming. Regular liming began in 1964. Up to 2000 six stages of liming were carried out. This resulted in larger areas of land with reduced acidity. The soils are poor in nitrogen, phosphorus and potassium so they require application of mineral fertilizers. Many farms have soil maps and maps showing the supply of phosphorus, potassium and some micro-elements. Radioactive pollution In 1986 due to the Chernobyl accident 23 percent of Belarus territory [including forest], where 2,200,000 people lived, was polluted with radioactivity. According to data from the Belarusian Research Institute for Soil Science and Agrochemistry the agricultural area polluted with caesium 137 was 1,500,000 ha and with strontium 90 nearly 500,000 ha. In 2001 agricultural production used 1,351,000 ha which are polluted with caesium 137 having a density level of more than 1 ki/km2 and 555,000 ha (1 ki =37kd k/m2) polluted with strontium 90 having a density of more than 0.15 ki/km2. Some polluted lands have been set-aside as a radiological reserve. Plants absorb strontium 90 more intensively than radioactive caesium 137. When water level and humus content increases, the stability of links between radionuclides and soil also increase and plants absorb them less intensively. During the first four years after the accident there were no great changes in radionuclide migration in the soil; the most radioactive part was the surface five centimetres soil humus layer. To reduce the amount of radionuclides in crops it is necessary to carry out measures, which will first of all include liming and the application of mineral fertilizers. The main agricultural areas polluted with radionuclides are in Gomel (58 percent) and Mogiljov (27 percent) regions where large additional investments are needed in order to produce normatively clean products (allowed levels of radionuclide pollution must not exceed 100 d k/l in milk, 500 d k/kg in beef - in Russia corresponding levels are 50 d k/l and 160 d k/kg respectively). [N.B. Ki - is a national unit of physical radioactivity while the international one is d k (beckerel). d k/l (beckerel per litre) is a unit of radionuclide content in agricultural products]. |

| 4. RUMINANT LIVESTOCK PRODUCTION SYSTEMS Historical Background.Traditionally livestock production in Belarus has been developed on raising horned cattle, since there is a wealth of pasture grasses on natural forage lands. It is no coincidence that the red Belarussian cattle breed was formed, and during a whole millennium has remained the most important factor of practical livestock production in the republic. Unfortunately, lack of proper breeding in the region led to almost absolute loss of this breed which in recent years was completely removed by more productive black and white breeds. At present black and white stock from Germany and Holland are the main breed in all regions of Belarus. Present Status in Livestock Production. Livestock include 4,300,000 head of cattle, 3,500,000 pigs, 30,000,000 poultry and a small number of horses, sheep and goats. Results of the national livestock census for 2000 are presented in Table 12. Large public and collective farms specialize in cattle and pig production while goat, horse and sheep are typical of private farms belonged. The rural population of the republic also keep considerable amounts of cattle, sheep and pigs.
After 1990 substantial changes in livestock production began, first of all a significant recession in livestock numbers as well as production took place that had been caused by changes in the economic situation in the republic (Table 13). The drop in livestock numbers has largely continued from 1995 to the present.
*Meat=beef+veal, mutton+lamb, pigmeat+chicken. As shown in Table 13 cattle numbers in the republic have fallen by
27 percent, sheep by 74 percent and only goats and horses were stable
since they are mostly kept on private farms and were not subject to
market forces; although number of horses began to fall after 2000.
Pig numbers fell from Public and Collective Sectors. Public and collective farms
have 88 percent of all agricultural land in Belarus; they keep 85
percent of all cattle , 62 percent of pigs, 7 percent of sheep but
do not keep goats. Average land area per farm in the public sector
is for The present status of livestock in the public sector depends to a great extent on activity of large farms and complexes. There are 112 complexes (1992 data) with capacity for 3,000 and more cattle; 109 complexes for 12,000 to 24,000; these had been built in every region before 1990 when in the USSR. Many cattle complexes are in the Central and South-Western zones of the republic where vast grass lands are available. The main productive system in the public sector is mixed cut-grazing cattle management. Practically all dairy livestock are on improved pastures for 140-170 days in the warm period. In the grazing season they yield 60 to 70 percent of the whole year’s milk. All feeder cattle on livestock complexes and farms are fed green mass, cut on natural hay lands as well as perennial grasses grown on arable land. In winter all cattle are fed haylage. Mixed cut-grazing system of cattle management fits the republic’s environmental and economic conditions. Public collective farms that apply this system of cattle management produce up to 70 percent of marketed milk and meat. Private sector. Lands of individual farms (which are few) as well as household plots, account for only 12 percent of all agricultural land. In that sector there are: cattle - 16 percent, horses - 46 percent, sheep - 89 percent, and all the goats (see Table 12). Private sector production is based on mixed cut-graze cattle management and is, at present, extensive owing to poor technical equipment and weak financial position. The private sector produces up to 30 percent of milk and beef. |

Vegetation Types. Forage resources are mostly from one vegetation type - forest-meadow - which covers three of the agro-climatic regions - northern, central, and almost all southern. Only a small part of the extreme south (near the Ukrainian border) is another vegetation type. According to the classification (Shklar, 1973) forest-meadow zone for 97.8 percent of the republic’s territory; within the zone (> 600 mm) pasture ecological conditions differ sharply depending on relief: humid flat and sloping areas are the main type - dry valley pastures, low-lying lands with additional ground water are the second type - lowland pastures (see Table 14).
