Dry grassy strip at edge of arable field.
No interactions present.
Leaves look a bit long and narrow to be Lotus corniculatus which has more rounded leaves. There is a narrow leaved Birds foot trefoil Lotus tenuis with narrow leaves but I dont know them well enough to offer a confident identification.
Stace says that leaflets can be lanceolate in L. corniculatus.
