Analysis of different types of soil by FTIR and ICP-MS

Fourier transform infrared spectroscopy (FTIR) and inductively coupled plasma mass spectrometry (ICP-MS) were used to study six types of farmland soil from different areas. The FTIR results showed that the infrared spectra of soil were mainly composed of the absorption band of clay minerals, organic matter and inorganic salts, such as carbonate, phosphate, manganate and so on. The mineral atlas of six soil samples were all of montmorillonite type. The ICP-MS test results showed that the available elements content of different types and colours of soil samples were different. There was significant lack status of available Ca between different types of farmland soil, the content of available Mg in Huludao soil was in the medium level, other areas were in the status of shortage. There was only significant lack status of available Mn and available Zn in Baiyin soil, the content of available Fe in Chenggong soil was in the status of shortage, the content of available Cu in all areas was particularly rich. The content of available P in Jining soil was rich, Luoyang and Huludao soil were in the medium level, the soil of Chenggong, Baiyin and Luliang were in the status of shortage. The content of available K in Luoyang, Chenggong and Jining soil was relatively rich, Luliang soil was in the medium level, the soil of Huludao and Baiyin were in the status of shortage. It is observed that the deeper the color of soil samples, the richer the amount of some available trace elements such as magnesium, copper, iron, manganese and zinc. According to the national classification standard of available elements content, we analyzed the nutrients of available elements content in the farmland soil of different areas, and implemented remedial measures for the lacking of available elements for all of the six areas. ©, 2014, Science Press.
