Institute of Land Reclamation today
For Belarus, where bogs and wetlands accounted for more than 40% of the territory, solving reclamation problems was and remains vital for economic development. Drainage amelioration has affected the economic growth and has had great social and aesthetic value. Due to recent changes, the center of gravity in the land reclamation activities of Belarus, instead of building new facilities and structures, has shifted towards the reconstruction and operation of existing systems.

Currently, the Institute of Land Reclamation is part of the Republican Scientific and Practical Center of the National Academy of Sciences of Belarus for Agriculture and provides scientific support for the use of over 4.5 million hectares of agricultural land, including 2.9 million hectares of drained land and 3 million hectares of hayfields and pastures, among which drained ones amount to 1.6 million hectares.

This article presents the results of three years of research on the growth, development and yield of sugar beets during irrigation. For the experiments we used a zoned variety of sugar beet – Belpol single-seeded. As a result of the studies, it was previously established that for soddy-podzolic light loamy soils, when irrigating  sugar beets, the maximum yield was observed on the variant with a lower limit of humidity  control of 70 % HB in a layer of 0–40 cm. It is shown that sugar beets are most sensitive to lack of moisture during the period from seedlings to the beginning of leaf closure in rows. A decrease in humidity in the calculation layer during the main period of root crop growth for a long time (control) led to the death of the suction root hairs of plants. According to the experimental options in sugar content they differed slightly on this. The difference was less than 1 %. The maximum value of sugar content on average for three years is in the variant with a lower limit of regulation of 70 % HB. It can be concluded that irrigation gives a significant increase in yield and does not reduce the sugar content in the root crop
