Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The aim of this study was to access the pH and soil degradation. Soil samples collected in eleven zones among three locations by zone were analyzed in the laboratory through pH Meter and the results indicates that pH of all soil samples is less than 5 (pH<;5) and the general average was found to be 4.4. Heavy materials like Fe, Cu, Mn, and Zn presented a high concentration level. The elements H+ and C were those with minimum concentration, the elements Ca and Na presents a low level concentration, and the elements due to fertilizers which are N, P, and K. The results indicate that the soil in the tea plantations in Country is acidic and this level of pH may result in deficiency of some base elements like calcium, magnesium, potassium and nitrogen.
