In precision agriculture there are several methods to describe an agricultural area, for example, yield mapping, remote sensing and local soil and plant analysis. Besides that, differences in the plant size are caused by several effects, therefore it is not easy to choose the right treating method. Generally applied fertilisers and organic fertilisers could

improve yield and the organic matter content of soil, optimize the soil water management etc. To select the appropriate methods rapid biotesting is the simplest method to take advice for us.

We have further developed the small pot experiment method. Photographs of the plants were taken for two weeks after germination. Growth curves were generated using image analysis.

In our rapid pot experiment, we could estimate the small differences of the treatments. The fertilised sample area has not significant differences. Besides N supply with the maximal K and P doses is not significantly larger but our treatments have negative effect to the seeds germination and plans growing. Furthermore, P and K fertilisers have not significantly effects, but the medium specialties of the area represent in this result. These results prove that the rapid biotest is appropriate for describe the different soil treatments effects.
