Title

TIME LAPSE CHEMICAL FERTILIZER MONITORING IN AGRICULTURE SANDY SOIL

Pages

  765-780

Abstract

 Geoelectrical resistivity, HYDROGEOCHEMICAL and soil properties analysis methods were used for chemical FERTILIZER monitoring in sandy soil at a palm oil plantation in Machang, Malaysia. The time lapse monitoring was done using these methods five times within a three-month period. The HYDROGEOCHEMICAL analysis was conducted over three auger holes to a depth of 1 m and sampled at 25 cm intervals. Chemical FERTILIZER was applied to the 21 x 21 m2 area after the first data set measurement. The areas outside of this fertilized zone are considered a nonfertilized zone. The other four data sets were acquired at about equal time intervals, thus giving a four-post fertilization data set. The HYDROGEOCHEMICAL measurements indicate that the cations content are relatively similar for every time lapse measurement. However, relatively higher changes of anions content occur at the surface level to a depth of 1 m. The NITRATE concentration above the limit for safe human consumption as it returns to the initial value about 100 days after fertilization. The geoelectrical model prior to fertilization showed similar resistivity values at near surface to a depth of about 75 cm with no significant occurrences of low resistivity values. Lower resistivity values were obtained during the second, third, fourth and fifth measurements within the chemically fertilized zone. In the last measurement, the resistivity values in the fertilized zone are almost similar to the nonfertilized zone. This indicates that the contaminant has dissolved into the surrounding environment within this time period.
