Soil Testing

Air Testing

Soil testing is a process in which nutrients, elements, contaminants, physical properties and others are checked by sampling and testing in laboratory for agricultural land, construction land and others. Soil testing can be used for a variety of purposes. For examples, a soil testing will tell you what nutrients are in your soil and what you might need to add (in the form of fertilizer) for successful grow crops. A soil testing can also tell you what contaminants are in your soil so that you know which methods to use for soil remediation. A soil testing can also comprehensively, systematically and accurately grasp the overall situation of soil environmental quality of a certain place for the site environmental evaluation of industrial land development and reuse. Alfa Chemistry offers a comprehensive range of soil tests and laboratory analysis solutions for the detection of a range of parameters to support your any needs.

Sample Collection and Types

Sample Collection

Soil sample collection is the most important and critical step in soil analysis. In general, soil samples are collected in two ways.

Grab sampling: In this method, soil sample is collected randomly from field.
Composite sampling: In this method, more than one sub samples mixed for sampling field. Specifically, collect multiple soil sub samples of 15 to 25 and then mix them completely.

Sample Types

Different testing items require different soil sample types. There are three common soil sample types.

Air-dried soil: It refers to soil that has been air-dried by natural conditions. Air-dried soil is mainly used for the detection of basic physical and chemical properties, such as nitrogen, phosphorus and potassium elements in soil.
Fresh soil: It refers to fresh samples collected. Fresh soil is generally used for microbial-related tests, such as soil microbial biomass carbon, microbial biomass nitrogen, microbial population, enzyme activity, etc.
Frozen soil: It refers to that soil samples are formed by the fresh soil samples frozen in -20 ℃ or -80 ℃. The sample is generally used for testing microbial diversity, such as the species and relative abundance of microorganisms in the soil.
