A physico-chemical characteristic of soil samples for an environmental management study at lake ecosystem
Abstract
The study area chosen for this investigation of soil quality was Samuthram lake, Thanjavur district to find out the impact of sewage wastes, open defecation, agricultural run-off etc., The pH of the sites was ranged from 8.1 – 8.4. The soil samples are alkaline in all the sites. TOC is important because it improves both the physical and chemical properties of soil and has several beneficial effects on agricultural soil quality. The percentage of total organic matter was ranged from 1.3 to 9.1. The nitrogen level of the study sites was ranged from 0.02% to a maximum of 0.14%. The phosphorous levels of the sites ranged from 0.01% to 0.08%. Phosphates are not toxic to people or animals unless they are present in very high levels. The result shows that the potassium levels ranges from a minimum of 0.02 – 0.04%. The above study indicates that pH and alkalinity of the soil samples are well above the safe limit. Other parameters are not more. In case of Agricultural run-off, open defecation, untreated sewage water may cause serious problem in future. So, there is an urgent management activity to protect this natural ecosystem.
