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.

The most important practice that contributes to rice production is nutrient management. However, if the nutrient plant required is insufficient, low production is unavoidable. Thus, this study was carried out to determine the soil fertility status of lowland areas in the municipality of Diplahan. Soil samples from each sampling site were collected in rice farms using a composite random soil sampling moving in a zigzag pattern. A depth of 0- 15cm soil samples were collected from 15 – 30 different places in 1-5 hectares. An air-drying procedure was done before it was carried to the laboratory for final testing. Soil samples were analyzed for pH, organic carbon, organic matter, nitrogen, phosphorous, and potassium following the BSWM (Bureau of Soils and Water Management) procedures. Furthermore, a soil fertility map was outlined through ArcGIS software by plotting local coordinates in Google Map. Results showed that the areas in 10 selected barangays in the municipality have moderate soil acidity, with a pH level that falls below the desirable range of 5.5 – 7.0 but no lower than 4.5. According to the results of the soil organic carbon analysis, all barangays have insufficient SOC. Only four barangays have the optimal soil organic matter content for lowland rice production. The study also revealed that only two (2) barangays receive an adequate amount of nitrogen, while the rest are considered deficient. Phosphorous-rich soils were found in two (2) barangays; the five (5) barangays have a medium content; and the remaining three (3) barangays have a low content. Lastly, no barangay in the municipality obtains an adequate amount of exchangeable potassium ranging from 82-246 ppm. Problem of insufficient nutrient requirements for rice crop production is widespread in the municipality.
