EESTI HARITAVA MAA KVALITEET Hugo Roostalu EPMÜ Mullateaduse ja agrokeemia instituut 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
