This can be explained by the fact that they are each herbaceous. Alternatively, this suggests that agricultural practices, for example fertilization and irrigation, may well contribute little to the greenness trends of cropland, although climate and CO2 fertilization could possibly play a major function in driving the greenness trends of cropped vegetation in this semi-arid area. The mean green-up magnitude with the barren land is equivalent to that from the herbaceous land cover kinds (i.e., grasslands and cropland), however the variation from the eight of 18 former is smaller than that on the latter, suggesting that barren land is extra homogeneous than grassland and cropland.Remote Sens. 2021, 13,Figure 4.
