1. Handling of fertilizer test reports.
The chemical fertilizer test report is an important basis for measuring the quality of chemical fertilizer, which is of great significance for ensuring the quality of agricultural production and agricultural products. In order to get an accurate fertilizer test report, the following steps need to be followed:
1.Collect samples.
When collecting samples, it is important to ensure that the samples are representative, i.e., the samples collected are representative of the fertilizer quality of the entire batch or production batch. At the same time, it is also necessary to pay attention to the number of samples to ensure that the number of samples is sufficient for subsequent detection and analysis.
2.Determine the test items.
Fertilizer test reports usually include a number of indicators, such as total nutrients, moisture, acidity, particle size, hardness, etc. When determining the test items, they should be determined according to product standards and customer needs. For example, potassium dihydrogen phosphate is a common compound fertilizer, and its testing items should include the content of nutrients such as phosphorus pentoxide and potassium oxide.
3.Perform detection analysis.
In the detection and analysis, it is necessary to use advanced instruments and professional technicians. In the detection of potassium dihydrogen phosphate, it is necessary to use spectrophotometer, conductivity meter and other equipment to test the content of phosphorus pentoxide and potassium oxide. At the same time, it is also necessary to pay attention to the accuracy of the experimental operation, such as the amount of sampling, the amount of reagents, the temperature of the experiment, etc., which will affect the accuracy of the experimental results.
4.Issuance of reports.
After the completion of the testing and analysis, a fertilizer test report needs to be issued according to the test data and product standards. The report should include basic information such as sample information, test items, test results, and conclusions.
