The lower Botna meadow is located on the territory of Causeni district, 6 km south of the Botna river into the Dniester meadow, and characterized by the same absolute altitudes as the Dniester meadow. As a result of overflow waters, the Lower Botna meadow, a permanent swamp territory was formed with an area of about 2500 ha. Dams were built in the Dniester meadow in the 1950s, and the Botna meadow is no longer flooded by the floods of the Dniester. The swamp was drained, the groundwater level dropped to 1.5-2.5 m. The dry land has been used in agriculture for more than 60 years. At present, the soil covers of this territory, according to the WBR-14 classification, is formed by deep humic clayey alluvial soils with extremely deep humiferous profile. The humus content greater than 1.00% to a depth of 2 m and content of mobile phosphorus is 10-12 mg/100 g soil on the entire humifer profile. These endemic soils are described in Moldova for the first time and, due to the high content of humus (4.5-5.0%) and mobile phosphorus (12 mg/100 g), they are an extremely good object for the implementation in the organic farming.
