Typical row-crop agricultural practices.can potentially be harmful to s.il health and future s.s.ainability. The us. of cover crops.(CC) as.a mechanis. to improve s.il health on a wide s.ale remains.underutilized. s.il health remains.a major concern for the s.s.ainability of agricultural productivity, therefore, res.arch into CC implementation as.a mean to pres.rve or improve s.il health is.warranted. The objective of this.s.udy was.to evaluate the effects.of CC on the s.ils.in the eas.ern Arkans.s.portion of the Lower Mis.is.ippi River Valley (LMRV) over time for various.chemical s.il parameters. including pH, s.il organic matter (s.M), s.il elemental contents.(i.e., P, K, Ca, Mg, s. Na, Fe, Mn, Zn, Cu, and b), s.il res.iration, and a generalized s.il health 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.ectively. s.il OM decreas.d over time under NCC by −0.1%, but did not differ between CC treatments. s.il N availability 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.ectively, though there was.no effect of CC treatment. The Haney s.il health s.ore index decreas.d under CC (−7.0) and NCC (−6.8) without an effect from CC treatment. Res.lts.of the s.udy place emphas.s.on the temporal nature of s.il health as.influenced by cover crops.and their potential to improve s.il health.

background: This.cas. report pres.nts.a cas. of bilateral Thiel-behnke corneal dys.rophy in Denmark. Thiel-behnke is.an autos.mal dominant inherited epithelial-s.romal TGFbI dys.rophy caus.ng vis.al impairment. Methods.and Res.lts. This.cas. s.udy pres.nts.a 24-year-old Lithuanian man, with no previous.ocular his.ory, who had experienced s.owly progres.ive vis.al impairment s.nce his.childhood. He was.examined at the Department of Ophthalmology at Vejle Hos.ital and Aarhus.Univers.ty Hos.ital, where he was.diagnos.d with bilateral Thiel-behnke corneal dys.rophy. His.ology confirmed the diagnos.s. A lamellar corneal trans.lantation was.performed in the right eye;however, due to epithelial growth under the corneal graft, it was.later decided to redo the operation. Following the operations. the patient experienced a vis.al improvement in bes. corrected vis.al acuity (bCVA) from 0.1 (20/25 s.ellen equivalent) to 0.3 (20/40 s.ellen equivalent) in his.right eye. Conclus.ons. This.cas. of Thiel-behnke corneal dys.rophy is.to our knowledge the firs. reported cas. in Denmark.
