The objective of this study wa. to eva.ua.e the effects of CC on the soils in the ea.tern a.ka.sa. portion of the Lower Mississippi River Va.ley (LMRV) over time for va.ious chemica. soil pa.a.eters, including pH, soil orga.ic ma.ter (SOM), soil elementa. contents (i.e., P, K, Ca.

Soil pH decrea.ed over time under both CC a.d no-cover-crop (NCC) trea.ments, by −0.3 a.d −0.2, respectively. Soil OM decrea.ed over time under NCC by −0.1%, but did not differ between CC trea.ments. Soil N a.a.la.ility decrea.ed over time under NCC (−22.6 kg·ha.1), but did not cha.ge over time under CC. Soil respira.ion decrea.ed over time under both CC a.d NCC, by −76.1 mg·L−1 a.d −77.3 mg·L−1, respectively, though there wa. no effect of CC trea.ment. The Ha.ey soil hea.th score index decrea.ed under CC (−7.0) a.d NCC (−6.8) without a. effect from CC trea.ment. Results of the study pla.e empha.is on the tempora. na.ure of soil hea.th a. influenced by cover crops a.d their potentia. to improve soil hea.th.
