The usage of chemical fertilizers in Thailand increased exponentially by more than 100-fold from 1961 to 2004. allows it to leach into groundwater faster, so there is positive relationship between the percentage of sands and NO3?-N concentration in groundwater wells. This study aimed to estimate the effect of soil texture on NO3?-N content in groundwater. Optical reflectance data obtained by remote sensing was used in this study. Our hypothesis was that the quantity of nitrogen leached into groundwater through loam was higher than through clay. Nakhon Pathom province, Thailand, was selected mainly because a report area where in fact the terrain is represented simply by a set topography mainly. It was discovered that categorized LANDSAT pictures delineated paddy areas as covering 29.4% of the analysis area, while sugarcane protected 10.4%, and 60.2% was represented by others. The nice reason behind this categorized landuse was to determine extra elements, such as for example vegetation, which can affect the amount of Zero3 directly?-N in garden soil. Ideally, bare garden soil would be utilized as a check site, however in truth, no such locations were obtainable in Thailand. This resulted in an indirect solution to estimation NO3?-N about various garden soil textures. Through experimentation, it had been discovered that NO3?-N measured through the loam in sugarcane (I = 0.0054, p < 0.05) was lower than clay represented by paddies (I = 0.0305, p < 0.05). This had a 155558-32-0 supplier significant unfavorable impact on the assumption. According to the research and local statistical data, farmers have always applied an excess quantity of fertilizer on paddy fields. This is the main reason for the higher quantity of NO3?-N found in clay than loam in this study. This case might be an exceptional study in terms of quantity of 155558-32-0 supplier fertilizers applied to agricultural fields. was the neighboring location of 0.8316 (p = 0.05) for HH, and I = 0.9548 (p = 0.01). However, the local Morans statistics shown HH-hh (I = 0.8182, p < 0.01), HH-ll (I = 0.3486, p < 0.01), LL-hh (I = 0.6534, p = 0.01), and LL-LL (I = 0.4065, p < 0.5). The effect of soil texture on nitrate-nitrogen content in groundwater was directly observed by its reflectance values through remote sensing. 155558-32-0 supplier It was found that NO3?-N measured through the loam in sugarcane (I = 0.0054, p < 0.05) was lower than clay represented in paddy (I = 0.0305, p < 0.05). This had a significant unfavorable impact on the assumption, the quantity of nitrogen leached into groundwater through loam was higher than through clay. According to the research  and local statistical data , farmers always apply excess fertilizer 155558-32-0 supplier to paddy fields. This is a main Rabbit polyclonal to EGFP Tag reason for the higher quantity of NO3?-N found in clay than in loam in this study. This case might 155558-32-0 supplier be an exceptional study in terms of the quantity of fertilizers applied to agricultural fields. There was high level of NO3?-N contaminants in urban areas, showing that there are other sources of contaminants. Therefore, there’s a have to investigate the mixed and multiple resources of contaminants in cities that can trigger hazard to metropolitan populations.
