Greening and Harvest Marker Examples

No bare soil between harvest of the main crop and second crop

Description

  • FOI = 6994688001 had a spring barley (Hordeum vulgare L.) claim for the (main) crop. This NDVI time series indicates a development of the main crop early in spring and harvest mid-summer and confirms the crop declaration as it matches well the NDVI time series of other spring barley FOIs in the neighbourhood (see AM Browser screenshot below). Another greening period after the first harvest indicates there was a second crop growing on the field and it was harvested end of September/in October. The absence of bare soil after the first harvest indicates that the second crop might have been undersown.

Bare soil between harvest of the main crop and second crop

Description

  • FOI = 7009330001 had a spring barley (Hordeum vulgare L.) claim. The greening period started in March and the crop was harvested in early July. After the harvest, we detected bare soil (marked by the red diamonds on the plot), which indicates an agricultural practice that removed vegetation and exposed bare soil, such as ploughing.

Gradual drop of NDVI within the harvest

Description

  • FOI = 6437372001 had the summer squash (Cucurbita pepo) claim. The plot shows bare soil observations before and at the beginning of the greening phase. Harvest phase was detected in early autumn, as expected for this crop based on the NDVI profile of the other summer squash FOIs in the neighbourhood (see AM Browser screenshot below). After the harvest, there were again bare soil observations but since the drop of the NDVI was gradual, this could indicate the crop leftovers after the harvest were left on the field to dry out.
