The first measurement campaigns in wheat and rapeseed crops

We are starting the first measurement campaigns in wheat and rapeseed crops to determine the nutrient supply to the plants. At the beginning of the research process, measurement zones were determined on which data necessary for further analysis and processing were collected. The zones were selected with the help of satellite imagery and based on measurements of soils and their types. The points were chosen so that the research was carried out for the most diverse growing conditions possible. Measurements were made of plant density per 1 m2. In each of the separated areas, 15 plants were selected for testing with the QED spectrophotometer and reference equipment. On each plant, one measurement will be made on the youngest leaf of the plant which will allow us to collect a sufficiently broad and representative database for the plants regarding their spectral response. Then, after the measurement campaign is completed, we will proceed with the preparation of plant samples, which will be sent to the district chemical and agricultural station. There, detailed analyses will be carried out, including nitrogen, potassium, phosphorus and plant dry weight. These parameters are key to understanding the nutritional status of the plants and the nutrients available in the soil. Sending samples to the chemical-agricultural station will enable us to obtain detailed laboratory data that will form the basis for further analysis. The results obtained will allow us to assess the value of the correlation coefficient, which is responsible for the quality of the fit between the model under test and the data obtained from the laboratory. This comprehensive approach allows us not only to analyze laboratory data, but also to take into account environmental conditions and differences in plant development in the area of the crop field.
