A comparative study of soil quality and water quality under various agricultural land uses. Palian Canal Area ,Village No. 1, Palian Subdistrict, Palian District, Trang Province The objective was to study the impact of soil utilization on water quality in the Palian Canal area. Water samples were collected in months from December 2023 to February 2024 by studying 8 chemical and physical water quality parameters and soil quality.
Results from soil quality studies It was found that soil fertility values with high nitrogen, potassium (K) and phosphorus (P) were the highest. In the rainy season, the moisture content of the soil is the highest. In the rainy season ( 0.21±0.04 ), the pH of the soil with the highest values is in the non-agricultural zone. In summer and in areas where animals are kept. In the dry season ( 7±0.00 ), the soil temperature is the highest. In summer ( 27.5±0.42°C )
As a result of the water quality study, the highest level of water transparency was in non-agricultural areas. In summer ( 96.8±0.42 ), the water temperature is highest in the area where it is cultivated. In summer ( 27.5±0.71 ), dissolved oxygen content is highest in areas where animals are grazing. Summer ( 11.00±1.41 ) The highest pH of water is in areas where there is no farming. In the rainy season Areas where there is no farming in the summer season and areas where animals are grazing in summer ( 7.00±0.00 ) The nitrate and phosphate values in the water are highest on average. The water hardness value has an average water value that does not walk more than the standard value. The water coming from the water source area is classified as a Category 1 surface water source because it is a natural quality water source. Agricultural waters and livestock watersheds Water is classified as a Category 2 surface water source because it is a water source that receives effluent from certain types of activities that must undergo a general water quality improvement process before being used for consumption.
