Abstract
Humid and boggy lands cover about 3.5 million ha in Lithuania. 3.02 million ha of humid and waterlogged lands have been drained (of
which 2.58 million hectares – by drainage) till the year 1990. During the latter years, large areas of drained lands became uncultivated in
agricultural industry due to the country’ public-social, demographic and economic reasons. With the increase of land productivity in
points the uncultivated agricultural areas decrease. The regression analysis of the increase of plant-growing production and land
productivity in points (due to drainage) shows that with the increase of the addition of land productivity in points (due to drainage) plant-
growing production increases as well (according to polynomial dependence). After the evaluation of the dynamics of the uncultivated
areas of agricultural farming lands, the increase of the land productivity in points due to drainage, the possibility of drainage breakdowns
and the plant-growing production (by typical regions), it is possible to state that the highest expediency of the renovation of drainage
systems is in the region of the Middle Lithuania Lowlands, the average – in the Pajūris Lowlands and the Baltic Highlands, the lowest one
is in the Žemaičiai Highlands.
Keywords: drainage; environment; productivity land; breakdown possibility; drainage renovation.
