Nitrogen determination

Determination of Nitrogen
Determination of Nitrogen

Soil is a living and mobile system with organic and inorganic compounds. In the depths of the soil, there are gaps with water and gases. The type of soil is determined by the different compositions of the substances that make up the soil. Many living communities inhabit the soil, such as fungi, worms, rodents and bacteria. There are many different soil types according to the physical, chemical and biological properties of the soil.

The formation of soil, climate, living organisms and vegetation on it are important factors. These factors lead to various changes in the structure of the soil and the organic substances in it and contribute to the formation of the soil.

For thousands of years, the land has reached today without seeing a problem, but in the current century, with the increase of industrial activities, the soil has started to lose power.

This inefficiency of the soil is due to the increase in the amount of sulfur and nitrogen compounds in the atmosphere caused by the burning of fossil fuels and various industrial activities. The sulfur and nitrogen compounds then fall into the soil as acid rains. This situation changes the structure of the soil and creates a danger for living things.

Nitrogen pollution is an international problem. It mainly occurs in regions where intensive agricultural activities are carried out. To combat this problem, measures such as the use of manure at the right time and the selection of advanced methods for the use of manure are used.

Nitrogen is one of the essential elements for all living things, but nitrogen directly affects the soil and products. If the amount in the soil exceeds the normal, the groundwater is polluted.

Therefore, it is important to determine the amount of nitrogen in the soil. Authorized laboratories also carry out nitrogen determination within the framework of soil measurements. These analyzes are based on the following standards:

  • TS 8337 ISO 11261 Soil Quality - Total Nitrogen Determination - Improved Kjeldahl Method
  • TS 12089 EN 13137 Properties of Wastes - Determination of Total Organic Carbon (TOC) in Wastes, Sludges and Sediments
