Research on Precision Soil Nutrient Detection Technology and Application Based on Mechanical Sampling
Abstract：To enhance the scientific nature of agricultural fertilization management and the accuracy of soil nutrient detection, this study investigated the precision soil nutrient detection technology based on mechanical sampling. By integrating remote sensing imagery and GIS analysis to optimize the layout of sampling points, combined with automated mechanical sampling and various detection methods (chemical analysis, spectral analysis, electrochemical sensing), a systematic study was conducted from four aspects: sampling process, error control, equipment calibration, and result traceability. Experiments were conducted on typical crop plots and plots with different soil types in Baoding City for comparative analysis. The results showed that this technology significantly improves the stability and representativeness of soil nutrient data, performing better than traditional detection methods in indicators such as organic matter, nitrogen, phosphorus, and potassium. The research results indicate that the mechanical sampling precision detection technology is applicable to various farmland environments and can effectively coordinate with intelligent fertilization systems, improving fertilizer use efficiency and promoting the development of agricultural intelligence.
