Soil Aggregate Tester

Soil Aggregate Tester is suitable for the analysis of aggregates in soil, environmental, and geological laboratories.

1. Soil aggregate structure plays an important role in soil fertility. A good aggregate structure generally has three properties:
① It has a certain size; too large or too small is not conducive to the formation of an appropriate pore ratio.
② It has multi-level pores; large pores allow air and water to pass through, while small pores retain water and nutrients.
③ It should have a certain degree of stability, including water stability, mechanical stability, and biological stability.

2. A good soil aggregate structure is the foundation of soil fertility. The relationship between soil aggregate structure and soil fertility is primarily manifested in the following aspects:
① Regulating the contradiction between soil moisture and air.
② Balancing the contradiction between the consumption and accumulation of soil nutrients.
③ Stabilizing soil temperature and regulating soil thermal conditions.
④ Improving soil tillability, which is beneficial for crop root development.

Soil Aggregate Tester determines the aggregate distribution under certain mechanical stability after dry sieving of air-dried samples. The aggregate distribution obtained by the dry sieving method is then mixed in the corresponding proportions and subjected to wet sieving in water to determine the quantity and distribution of water-stable large aggregates.

• The structure mainly consists of a speed regulator, reduction gear, and balancing frame, featuring a compact size, lightweight design, and silent operation.

• It has an aesthetically pleasing design and is equipped with safety features such as an automatic parking device, emergency stop mechanism, and leakage protection.

• The structure is advanced, performance is excellent, and it is convenient and flexible to use with a clamping sleeve screen.
