C is a crop management factor - a ratio which compares the soil loss with that from a field under a standard treatment of cultivated bare fallow.
Owing to crop rotation, agricultural land cover is highly dynamic (cereal crops, cultivated pastures, fallow land); thus, both ground reference data from 2011 as well as the various high resolution reference images contain a high probability of being different from the situation on July 13 , 2008(Landsat 5 TM acquisition date).
Much of the arable area consists of fallow cultivated land or steppes and mountains that serve as pastureland.
The presence of other, less salt-tolerant plant taxa is suggestive of more productive habitats and may indicate that cultivated areas left fallow were also important areas for grazing following harvests.
Despite a considerable increase in 1999, which fell again in 2010, the average size of agricultural plots (home gardens, cultivated areas, and fallow) steadily decreased throughout these periods.
We evaluated the effectiveness of uncropped cultivated margins (UCM), spring fallow (SF) and cropped conservation headlands with (CH) or without fertiliser inputs (CH NF)) in sustaining plant species diversity and rare species, in England, UK.
Croplands (mainly maize) exhibited higher ranges of GPP (200 2500 g cm−2 yr−1) and ET fluxes (150 800 mm yr−1) variability, relative to other land cover types, primarily due to the presence of fallow versus cultivated lands.
Of 23 species restricted to one land-use type, 16 were found on cultivated land or recent fallows, 8 of them being categorized as uncommon in West Africa.
The effectiveness of reduced applied irrigation volumes, sealing of earthen irrigation canals, rotational fallowing of cultivated land, reduced fertilizer loading, and enhanced riparian buffer zones, implemented individually as well as concurrently in various combinations, is explored.
In comparison, actively cultivated lands and advanced (>16 18 months) fallow fields, the land surfaces existing before and after the threshold period, have ROCs≤4%.
