Szukana fraza: [Abstract = "Pedological and phylosociological investigation permitted the selection out of four experimental methods of neutralization used in 1974 that which had given the best results, i.e. the combination of two\-layer mixing of magnesiumoxide lime and ground phosphate rock. After 20 and 25 years pH value in KCl varied from 3.9 \- 7.8 in horizon 0 \- 20 cm and from 3.0 \-3.6 in horizon 25\-50 cm, never falling below 3.0. The content of total sulphur was reduced ten times on average after 25 years."]
