Abstract. Roostalu, H. 2000. Quality of arable land in Estonia. – Transaction of The Estonian
Agricultural University
Only 50 - 60 % of arable land in Estonia is characterized by a high degree of fertility, where it
is possible to foster competitive agricultural production. The share of low fertility, droughtly and coarse
rich soils as well as eroded soils, nutrient - poor acid soils and overmoistened soils in the arable area,
where agricultural production is not profitable, is relatively large. On all arable land soils with a low or
very low content of lactate soluble potassium account for 40 - 65 %. Considerable phosphorus deficit
occurs in 20 - 35 % of soils in the arable area. The soils of Põlva, Valga and Võru counties are
exceedingly poor in humus. The available water supply in the metric profile of arable soils at the
beginning of vegetation period varies from 140 to 255 mm
