location：Soil aggregates are the core indicators for evaluating soil structure stability and fertility, directly affecting soil moisture retention, nutrient supply, and crop root growth. The soil aggregate analyzer uses a combination of dry and wet sieves to accurately determine the quantity and distribution of soil mechanical stability and water stable aggregates, providing key data support for soil quality assessment, agricultural management, and ecological restoration. This article systematically elaborates on the importance of soil aggregate analyzer from the perspectives of technical principles, performance characteristics, application scenarios, and industry pain points, and combines practical cases to illustrate its value.
The importance of soil aggregate analyzer
Soil aggregates are the basic units of soil structure, and their stability and distribution are directly related to soil pore configuration, water movement, nutrient cycling, and erosion resistance. The traditional aggregate analysis method relies on manual operation, which has problems such as low efficiency, large errors, and poor repeatability. The soil aggregate analyzer achieves automation and precision in the analysis of dry (mechanical stability) and wet (water stability) aggregates through standardized mechanical oscillation and intelligent control, becoming an essential tool for soil science research and agricultural technology promotion.
Working principle and technological advantages
1. Core detection principle
Dry wet screening combined analysis method:
Dry screening analysis: Perform mechanical oscillation on air dried soil samples to determine the particle size distribution of mechanically stable aggregates (0.25mm~10mm).
Wet screening analysis: Mix the aggregates obtained from dry screening in proportion and shake them in water to determine the quantity and distribution of water stable macroaggregates, and evaluate the soil's resistance to water erosion.
Standardized operating procedures: Strictly follow internationally recognized methods to ensure data comparability and scientificity.
2. Technical advantages
High precision oscillation control: The vibration frequency can be adjusted from 0-56 times/minute, and the amplitude can be selected from 30mm/40mm/50mm to meet the needs of different soil types.
Intelligent safety design: equipped with multiple safety mechanisms such as emergency stop button, leakage protection, and locked rotor protection to ensure operational safety.
Efficient parallel processing: The cross shaped oscillating frame supports 4 sets of standard screens working simultaneously, greatly improving detection efficiency.
Digital operation interface: digital speed controller and timer, supporting precise setting and real-time monitoring of speed and time.
