Determination of nutritional status of winter wheat using multispectral imaging
Original language description
The knowledge of spatial variability of nutritional status in plants is important for adequate variable rate application of fertilizers. In this paper are presented initial results of an ongoing study which verify using of multispectral imagery to estimate a continuous image of nutritional status in winter wheat. Verification was carried out in 2010 at two different locations with areas of 53 and 38 ha in the Czech Republic. Plant inorganic analysis (content of N, P, K, Mg, Ca and S) and ground measurement of LAI were carried out in winter wheat at BBCH 30 in regular sampling grid 150 x 150 m. Results were related with the broadband multispectral images (G, R, NIR bands, NDVI index) from an aerial survey using two techniques, multiple linear regressionand decision trees. Both methods shown promising results, reaching values of 0.83 for the R square with the multiple linear regression and a hit rate of 57.8% with the decision trees.
