Abstract
Darbā tika analizēts dzelzs, cinka, vara, kālija un fosfātjonu saturs mellenēs (Vaccinium myrtillus L.), krūmmellenēs (Vaccinium corymbosum) un to augsnē. Melleņu un augsnes paraugi tika ievākti meža teritorijā, kur tika mēslots ar vieglajiem koksnes pelniem. Krūmmelleņu ogu un augsnes paraugi tika ievākti privātmājas teritorijā, kur netika izmantots nekāds mēslojums. Veicot sauso mineralizāciju, ar liesmas atomabsorbciometrijas metodi noteikts dzelzs, cinka un vara saturs, fotometriski tika noteikts fosfātjonu saturs un ar liesmas fotometriju tika noteikts kālija saturs. Iegūtie rezultāti tika apstrādāti, izvērtēts noteikto elementu saturs mellenēs un krūmmellenēs, kā arī iegūtie rezultāti tika salīdzināti ar literatūras datiem.
The purpose of this work was to analyze iron, zinc, copper, potassium and phosphate Iions in blueberries (Vaccinium myrtillus L.), highbush blueberries (Vaccinium corymbosum) and its soil. Blueberry and soil samples were collected in forest area that was fertilized with fly wood ash. Highbush blueberries and it soil were collected near at private house area where no fertilizer was used. Perfom dry mineralization of blueberries, iron, zinc an copper were determined by flame atomic absorbtion spectroscopy, potassium by flame photometry and phosphates were determined by photometry. The obtained results were statistically processed and compared with litearture data.
