Different Methods for Farm Soil Analysis
In addition to the land and seeds, a farmer’s soil is one of the most important factors in their business. In fact, many farmers take immense pride in how well they maintain their soil and the crops it produces. That said, more and more farmers are using laboratories to their advantage by submitting soil samples for analysis. The purpose of soil analysis is both to ensure their soil is safe and healthy, but also to identify areas of improvement. If you’d like to learn some of the different methods for farm soil analysis, continue reading our guide below.
Mechanical Analysis
There are a variety of sampling methods, but two of the most common are composite and grid sampling. Composite requires taking multiple random soil samples from a designated area and then combining the random samples into one. Grid sampling is much more time-consuming as it requires tracing grids over the farm based on soil type and then collecting samples. Both composite and grid sampling lead to mechanical analysis and chemical analysis (more on that later).
Mechanical analysis tests the soil and measures the particles and organizes them by size and weight. The reason you’d want to separate them accordingly is that you can then identify the components of the soil. Important components to measure include clay and sand as they can affect a crop’s ability to grow.
Chemical Analysis
To reiterate, chemical analysis also starts with various sampling procedures like composite and grid sampling. For farmers looking for more detailed information, they’ll often resort to chemical analysis, which uses lab procedures like chromatography. Among the various farming applications of chromatography are detecting pH, pollution, and metal levels in soils. Moreover, chromatography is a method that allows farmers to analyze the purity of their soil, which is especially important for organic farmers. The reason organic farmers take their soil’s integrity seriously is because consumers in recent years want to know that their produce doesn’t contain harmful pesticides and other chemicals.
As you might suspect, there are several other methods for farm soil analysis, but most of them fall under the umbrella of mechanical or chemical analysis processes. As a farmer, you can benefit significantly from these soil tests for two main reasons. First, soil tests help you improve your land and crops. Second, you can prove to consumers and buyers that you take your soil seriously.
