N and P variation in Groundwater in Wet Zone and Dry Zone in Sri Lanka due to Fertilization of Paddy Crop
      S.K.Gunatilake
Abstract: Nitrate and phosphates are the main contaminants in groundwater due to application of fertilizer in agricultural sector. Therefore, present study was conducted to identify the general trend of fertilizer usage in the paddy sector and how much N and P affect to underground water. A total of 142 groundwater samples were collected from drinking water wells, covering two different climatic zones. The physico-chemical parameters were determined using standard procedures (APHA1992). pH and EC, fluoride, nitrate, phosphates and sulfates were measured. The average NO3–N concentrations in groundwater before fertilization in wet and dry zones are 1.47 and 0.98 mg/L.
