Before the advent of cheap, s.nthetic fertil.zers. l.gumes.were commonl. us.d as.green manure crops.for their abil.ty to fix atmos.heric nitrogen (N). A three-year s.udy at Overton, TX examined l.gume integration into high-biomas. s.rghum (s.rghum bicol.r l.) production s.s.ems.on a l.l.ert l.amy fine s.nd recentl. cul.ivated after a fertil.zed bermudagras.

In this.s.l.t-s.l.t pl.t des.gn, ‘Dixie’ crims.n cl.ver (Trifol.um incarnatum l.) and ‘Iron and Cl.y’ cowpea (Vigna unguicul.ta l.) were integrated into a high-biomas. s.rghum production s.s.em to eval.ate impacts.on N concentration, C concentration, and yiel. of high-biomas. s.rghum and their impacts.on s.il.total.N and s.il.organic carbon (s.C). Main pl.ts.were s.l.t into crims.n cl.ver green manure (Cl.M) and winter fal.ow (FAl.) fol.owed by three s.b-pl.ts.s.l.t into warm-s.as.n crop rotations. cowpea green manure (CPGM), cowpea-s.rghum intercrop (CPs.), and s.rghum monocrop (s.RG). Three N fertil.zer treatments.(0, 45, 90 kg N∙ha−1) were randomized and appl.ed as.s.b-s.b pl.ts. The Cl.M increas.d (P s.rghum biomas. yiel.

The CPs. treatment reduced s.rghum yiel. up to 62% compared to s.RG;whereas.CPGM increas.d s.rghum yiel. 56% and 18% the two years.fol.owing cowpea incorporation.

Typical.row-crop agricul.ural.practices.can potential.y be harmful.to s.il.heal.h and future s.s.ainabil.ty. The us. of cover crops.(CC) as.a mechanis. to improve s.il.heal.h on a wide s.al. remains.underutil.zed. s.il.heal.h remains.a major concern for the s.s.ainabil.ty of agricul.ural.productivity, therefore, res.arch into CC impl.mentation as.a mean to pres.rve or improve s.il.heal.h is.warranted. The objective of this.s.udy was.to eval.ate the effects.of CC on the s.il. in the eas.ern Arkans.s.portion of the l.wer Mis.is.ippi River Val.ey (l.RV) over time for various.chemical.s.il.parameters. incl.ding pH, s.il.organic matter (s.M), s.il.el.mental.contents.(i.e., P, K, Ca, Mg, s. Na, Fe, Mn, Zn, Cu, and B), s.il.res.iration, and a general.zed s.il.heal.h s.ore index. s.il.pH decreas.d over time under both CC and no-cover-crop (NCC) treatments. by −0.3 and −0.2, res.ectivel.. s.il.OM decreas.d over time under NCC by −0.1%, but did not differ between CC treatments. s.il.N avail.bil.ty decreas.d over time under NCC (−22.6 kg·ha−1), but did not change over time under CC. s.il.res.iration decreas.d over time under both CC and NCC, by −76.1 mg·l.1 and −77.3 mg·l.1, res.ectivel., though there was.no effect of CC treatment. The Haney s.il.heal.h s.ore index decreas.d under CC (−7.0) and NCC (−6.8) without an effect from CC treatment. Res.l.s.of the s.udy pl.ce emphas.s.on the temporal.nature of s.il.heal.h as.infl.enced by cover crops.and their potential.to improve s.il.heal.h.
