ABSTRACT:
The soil samples were collected near roadsides of Thoppur hills at three different locations. The total length covered by road sides was 11km. So, the soil samples were collected at three different points. While going up to Thoppur hill, the soil sample collected between 1 and 2 kilometer was labeled as point1, second sample collected near 6th kilometer was labelled as point 2 and third sample collected near 10th kilometer as point 3. The processed samples were sent for the analysis of physio-chemical properties. The observed results show that the pH was ideal for plant growth in all three points. Organic carbon content was within normal limit ensuring conducive environment for the plant growth. The nitrogen level was high in point 2 and 3, whereas it was low for sample collected from point1. The phosphorus, potassium content was found to be low in all three locations. Sufficient amount of calcium, sulphur was observed in all three points. Likewise, magnesium, iron, manganese, copper observed was higher in all the soil samples studied at different points. Deficiency of zinc, boron was observed in these soils, whereas, humus content was good in all the samples. Total mineral content was high with point1 compared to other two points.
