This is an overview of the various service labs in SPESS. It includes information on soil testing, plant analysis, cotton fiber testing, wetland (wet) soils testing, and other analyses related to soils and plants.
Fertilizer comes in different strengths and blends. The three numbers on the fertilizer bag show the percent by weight of the three major nutrients. The first number is always the percent nitrogen (N). The second is always the percent phosphate ( P2O5). The third number is always the percent potash (K2O).

CAIRL has a wide variety of analytical instruments to do various analayses of water quality, pollution chemistry and organic chemistry. For example, the Varion 3800C Gas Chromatography has an FID and ECD detector and is customized to analyze gas samples mainly for CH4, CO2 and N2O. Another piece of equipment is the Pyrolysis GC/MS CDS 5000 pyroprobe attached inline with Varian 3900 GC and Saturn 2000 Masspec.
