Introduction

GB/T 42485-2023 Soil quality - Determination of nitrate nitrogen, nitrite nitrogen, and ammonium nitrogen - Manual analysis method using potassium chloride solution leaching

The GB/T 42485-2023 standard specifies a manual analysis method for determining nitrate nitrogen, nitrite nitrogen, and ammonium nitrogen in soil using potassium chloride solution leaching. This method is widely used to assess soil quality and nutrient availability in agricultural and environmental studies.

The manual analysis method involves extracting the soil samples with a potassium chloride solution, followed by analyzing the extracted solution for nitrate nitrogen, nitrite nitrogen, and ammonium nitrogen using appropriate analytical techniques. The standard provides detailed procedures for sample preparation, extraction, and analysis, ensuring accurate and reliable results.

This method is advantageous as it requires minimal equipment and can be easily performed in a laboratory or field setting. It is suitable for routine analysis of soil samples and provides valuable information on soil fertility and nutrient management.

The GB/T 42485-2023 standard plays a crucial role in ensuring the accuracy and consistency of soil quality assessments. It serves as a valuable resource for researchers, environmentalists, and agricultural professionals working towards sustainable land management and soil fertility improvement.
