The results of analysis of nutrients and heavy metals in the soil of Oak (tree) stands of Kvemo Kartli region.
2020
In identify the reasons for the delay in the natural regeneration of oak forest in the Kvemo Kartli region, soil samples were taken separately from soil incisions made in the sample plots to study the nutrients and heavy metals at a depth of 0-20 cm. Laboratory analysis determined the content of exchange potassium (mg/kg), from heavy metals: cadmium – Cd (mg/kg), copper – Cu (mh/kg), lead – Pb (mg/kg). Comparison of the obtained data with the gradation of the evaluation of general and forms for assimilation of potassium shows that the potassium content does not influence the renewal of oak forest. Also, the content of copper lead and cadmium are within the permissible limits. Based on the data obtained, the unsatisfactory condition of the oak tree stands renewal is not caused by soil factors.
