Abstract

Integrated geoelectrical resistivity, hydrogeochemical and soil properties analysis methods were used to study the area that has been applied with fertilization for long duration and non-Fertilization in Machang, North Kelantan. The Machang plain is covered with Quaternary fluvial sediments overlying granite bedrock. The drainage system is dendritic with the main river flowing into the South China Sea. In this study, the area was divided into two sites. Site-1 is the non-fertilized site, and Site-2 is the regularly-fertilized site. At shallow depth from the surface to depths of 75 cm a lower average geoelectrical resistivity values were obtained from the regularly fertilized site which has not been fertilized for the last ten months prior to the survey. The average resistivity values were around 0.366 times less in unfertilized sites. Residual nitrate and chloride were still present at the regularly chemically fertilized sites. At sites where no chemical fertilizer was added, the nitrate and chloride concentration were also found. These are due to the faces excretion of from the farm animals. The presence of nitrate and chloride content in pore water reduced the resistivity values. Thus despite low moisture content, the resistivity values to remain low. Normally, resistivity values are inversely proportional to moisture content for area with similar soil condition.

Abstract

Evaluation of the fate of nitrate and analysis of shallow soil water in a tobacco plantation area were conducted using integration of soil properties and hydrogeochemical analysis, and geo-electrical resistivity methods, taking measurements four times within a three-month period. The sampling data were taken in two areas: a fertilized and a nonfertilized zone. Chemical fertilizer was introduced to the fertilized zone after the first data acquisition. Hydrogeohemical analysis of the soil water was conducted from the surface to a depth of 1 m at an interval of 25 cm. The results show that the cations in the soil water were quite comparable for each monitoring time. Conversely, relatively larger changes in anion content occurred at the surface until a depth of 1 m. In particular, the nitrate concentration reached its maximum level at about 67 days after fertilization and returned to its initial value approximately 195 days after fertilization. The geo-electrical resistivity profiles exhibited no indication of low resistivity values prior to fertilization near the surface. However, lower resistivity values were found in the fertilized zone at the second and third measurement. The result shows that the adjoining environment dissolved the nitrate concentration in the pore soil within the three-month time period.
