摘要: Kadmium-szennyezes (270 kg/ha CdSO4) utohatasat vizsgaltuk a talaj Cd-tartalmara, humuszfrakcioira, talajlegzes intenzitasara, tenyeszedenyben nevelt hat novenyfaj novekedesere es hajtasok elemtartalmara. A mereseink alapjaul szolgalo barna erdotalajt szabadfoldi nehezfem-szennyezeses tartamkiserlet Cd-terhelt kontrollparcellainak felso 20 cm-es retegebol vettuk, terheles utani nyolcadik evben Gyongyos melletti Taspusztan (Karoly Robert Foiskola kiserleti tere). kiszaritott, kezelesenkent homogenizalt talajmintakbol meghataroztuk kiralyvizzel ammonium-acetat + EDTA-val kioldott elemtartalmat (23 elemre). legzesintenzitast elektronikus manometerrel masodpercenkent rogzitett nyomasadatok alapjan allapitottuk meg 70%-ra nedvesitett 30 napig inkubalt talajbol. szerves anyagainak meghatarozasat az un. ket oldoszeres eljarassal (NaOH NaF) vegeztuk. Cd-szennyezett kontrolltalajon novenyfajjal (retek, repcseny, sarga viola, soska, laboda, oroszlanszaj) tenyeszedeny...
