No-till identification by crop residues on the soil surface using the multi-temporal integral index minNDTI |
|
|
The study analyzed the possibility of using the multi-temporal spectral index minNDTI to identify farms using no-till. Using the Google earth engine platform, satellite images of the Sentinel 2 system were obtained, processed and analyzed for two time periods. Based on the data obtained, NDTI images were constructed for periods of fieldwork, as well as multi-temporal minNDTI images. As a result of the statistical analysis, significant differences were found between the NDTI values of the samples from the plowing and no-till options for two time periods in which the field work was carried out and between the multi-time values for two years of research. Based on the dynamics of the values of the multi-temporal index minNDTI, a map of the probability of assigning fields to direct sowing was constructed.
