Analysis of Plants, Soils and Fertilizers

How well a particular plant or a crop performs is very dependent on the fertility of the soil. For a complete picture, parameters like carbon, nitrogen, and nitrate, but also certain metals need to be assessed. On the other hand, contaminants must be avoided. Bruker’s spectroscopy solutions enable a rapid analysis in the lab or in the field.

XRF is a fast, nondestructive technology for elemental analysis of macro-nutrients, micro-nutrients, and heavy metals of the entire plant system, including seeds, soil, irrigants, fertilizers, the root system, and the shoot system. Bruker’s Elemental Analyzer portfolio includes high-throughput lab-basedED-XRFandWD-XRF,point-and-shoothandheld XRF,micro-XRF, and ultra-trace analysisTXRFspectrometers.

Bruker offers both FT-IR and FT-NIR spectrometers widely used for soil analysis applications.FT-NIR spectroscopyoffers a fast and cost-effective tool for analyzing total carbon and total nitrogen in soil, two parameters that help to better understand and manage the effects of fertilization.

Infrared spectroscopyis increasingly being used as a supplement and alternative to conventional soil testing methods for the estimation of many soil functional properties and plants properties.

近红外光谱允许measurement of larger sample volumes and is less demanding in terms of sample preparation. While MIR requires grinding to fine particles, it often achieves more accurate calibrations and is useful for a greater number of parameters.

Examples of parameters which can be monitored:

Organic and inorganic C
Total carbon, total nitrogen
Nitrate
Potassium, Aluminium, Calcium ...
pH

肥料的分析

虽然FT-NIR spectroscopyis mainly used for the analysis of organic substances, it can also be utilized to determine the concentration of minerals, since they have an influence on the shape of the water absorption band. Thus, in e.g. a granulated NPK fertilizer total nitrogen, total phosphorus and water-soluble potassium content can be determined. In addition to the sum parameters (e.g. total nitrogen), the individual components such as ammonium nitrogen or nitrate nitrogen, etc. can also be determined. Moreover, the determination of added minerals or elements such as calcium or magnesium can be possible, depending on the matrix and concentration.
