Soil agrochemical analysis work skills

The first is methodological exploration: there are many soil agrochemical analysis projects and there are many analytical methods. Some of them are classical methods, some are recommended methods, and some are general methods. Soil agrochemical analysis requires fast, batch, low-cost, and accurate, and each laboratory can conduct method comparison based on its own situation, and share experiences and experiences. Such as the selection of extractants, the choice of colorimetric wavelength, the choice of redox agents, etc.
The second is data review: Soil agrochemical analysis data have certain relevance and range of values, such as soil organic matter and total nitrogen, total nutrients and available nutrients. The laboratory personnel should have a general understanding of the range of values ​​of some soil agrochemical analyses.
The third is data comparison: There are mainly mutual comparison methods between laboratories. Different laboratories send the same sample to each other for comparison of test values, reference sample comparison methods, and comparisons using reference samples issued by superior departments. The standard sample insert method is used to insert a standard sample of known concentration into the sample to be tested. Error comparison method, parallel test according to error theory.
The soil agrochemical information collection system produced by Top Instrument Co., Ltd. is a kind of public opinion data processing equipment, which realizes the automation of soil testing and fertilization information acquisition.
