The study of soil element content in rice cultivation area in Thay Lad village, Banglee sub-district, Thawung district, Lopburi province.

Abstract

The main objectives of this study were to analyze the quantity of soil nutrients and soil pH with KU soil test kit and another soil nutrients with X-ray fluorescence technique. Also study the acid base status with the 913 pH meter. Samples from 3 plots of paddy fields, 9 samples from the Thay Lad village, Banglee sub-district, Thawung district, Lopburi province. The results show that the acid base status were in the range of 6.92-7.20. The nutrient contents were low-medium nitrogen, low-medium phosphorus, medium- high potassium, while the another nutrient contents such as calcium, iron, silicon and titanium had the percentage concentration of the elements in the compound compared to all compounds in the soil were 4.15-7.09, 42.74-46.17, 36.17-38.61 and 3.31-3.44, respectively. Once the soil quality had been studied, phosphorus content should be increased and acid base status in soil should be reduced in the next crop.
