The main purpose of soil preparation is to ensure the stability and long-term preservation of soil samples.
Soil sample preparation includes a series of processing processes after collecting soil samples from the field, including mixing, drying, grinding and sieving. Freshly collected soil samples need to be dried in time to inhibit the activity and chemical changes of soil microorganisms, so as to make the analysis results more stable and facilitate long-term preservation.
Steps of soil preparation
- Remove intrusive bodies and new bodies: First, remove intrusive bodies such as plant roots, insect corpses, bricks and stones, and new bodies such as iron and manganese nodules in soil samples.
- Mixing: Mix the collected soil samples to ensure the representativeness of the samples.
- Drying: Dry the mixed soil samples to inhibit microbial activity and chemical changes.
- Grinding and sieving: Grind and sieve the dried soil samples for subsequent analysis and long-term preservation.
The impact of soil preparation on analysis results
Through soil preparation, the uniformity and stability of soil samples can be ensured, and the impact of microbial activity and chemical changes on the analysis results can be reduced, thereby improving the accuracy and reliability of the analysis results. In addition, the prepared soil samples are easier to store and transport for a long time.
