Soil Total Organic Carbon Analyzer

Total organic carbon (TOC) and carbon-to-nitrogen ratio (C/N ratio) are important indicators of organic matter in soil, used to assess soil quality and the decomposition process of organic matter.

Total organic carbon refers to the total amount of organic carbon in soil, including plant and animal residues, organic fertilizers, and microbial metabolic products. It is a comprehensive indicator of soil organic matter content.

The significance of the soil carbon-to-nitrogen ratio lies in providing information about soil nutrient cycling and organic matter decomposition. A low C/N ratio typically indicates faster decomposition of organic matter in the soil, relatively higher organic nitrogen content, and potentially higher soil fertility. A high C/N ratio typically indicates slower decomposition of organic matter in the soil, relatively lower organic nitrogen content, and potentially lower soil fertility. Generally, the typical range of the soil carbon-to-nitrogen ratio is between 10:1 and 20:1. Different soil types can influence the soil carbon-to-nitrogen ratio.

Soil total organic carbon and the carbon-to-nitrogen ratio have significant impacts on soil quality assessment, nutrient cycling processes, and soil fertility management. Appropriate levels and ratios help maintain soil health and fertility.

The following parameters can be tested:
1. Total organic carbon (TOC), carbon-to-nitrogen ratio, ammonium nitrogen, available phosphorus, available potassium, nitrate nitrogen, hydrolyzable nitrogen, total nitrogen, total phosphorus, total potassium, organic matter (Chulim method), organic matter (extraction method), pH value, salinity, and moisture content.
2. Trace elements in soil: soil calcium, soil magnesium, soil sulfur, soil silicon, soil boron, soil iron, soil copper, soil manganese, soil zinc, soil chlorine.
