Sub-plots were assigned to two cropping systems Egyptian clover (Trifolium alexandrinum L). followed by corn (Zea mays L). (common cropping system, CCS) and the drought-adopted cropping system (DACS) oat (Avena sativa L). followed by sudangrass (Andropogon sorghum subsp. drummondii).
Additional reasons may explain why grain legumes are not very common in high-input cropping systems.
The factors were cropping systems including (a) common bean (Phaseolus vulgaris L). sole cropping (40 plants m−2), (b) dill (Anethum graveolens L). sole cropping at different densities (25, 50 and 75 plants m−2) and (c) the additive intercropping of dill + common bean (25+40, 50+40 and 75+40 plants m−2).

This appeared to be a more protective land use than annual cropping systems, which is common for the Upper Lango and Medo areas, where 'very severe' soil loss was observed.
Durum wheat was included as a common high-value cash crop in all the cropping systems to evaluate the carryover effects of rotation.
It includes dates of soil coverage, soil cultivation, and seeding and harvest of summer catch crop (s-cc) and winter wheat for the calculation of erosion with BoBB.3 In cropping systems with ploughing, it is common to combine rotary harrow and seeding in one pass.
Nitrogen (N) loss through nitrate leaching in arable cropping systems in China has been recognized as one of the most common agricultural sources of groundwater contamination.
This tropical ant species was found to be common and abundant in agroecosystems, with a high nest density and preference for the central, crop-growing zone of annual cropping systems.
Different cropping systems also influence SOC storage.
