INVESTIGATION OF ESSENTIAL MICRONUTRIENTS LEVELS IN VARIOUS LATERITE SOILS FROM KANYAKUMARI DISTRICT, TAMIL NADU
In the present study, the levels of some essential micronutrients (Fe, Co, Zn and Cu) were determined in the laterite soils located in Kanyakumari district, Tamil Nadu. The aim of the present work is to assess the levels of micronutrients like Iron, Copper, Zinc and Cobalt in soils and analyze the aptness of the soil for crop production.
The soils were processed and analyzed for these metals using atomic absorption spectrophotometer.
The results showed that the levels of Fe were higher (146.98mg/kg) in soils obtained from Munchirai(S1). This trend was followed by Cu with the highest amount (25.65mg/kg) determine at Melpuram(S2). Similarly, Zn and Co had their highest levels (96.76 mg/kg Zn, 21.08 mg/kg Co) in soils obtained from Thuckalay(S5) and Melpuram(S2) respectively.
These study revealed that the accumulation of these micronutrients depended not only on the availability of these metals in the five stations but also on other factors which were not considered in the study.
The study was done in the Department of Chemistry, Sree Devi Kumari Women’s College, Kuzhithurai, TN, India
