The restoration of a structurally degenerated soil

, : The restoration of a structurally degenerated soil. Soil Sci. Soc. Amer. Proc, 21: 131-134

Compact soil cores were prepared by moulding and air-drying puddled soil with and without addition of 0.5% (by weight) of lucerne meal, or of limestone to raise the pH from 5.6 to 7.0 + 1000 lb/acre of 5-20-20 fertilizer before puddling. A fourth type of core was prepared by puddling with a chlordane emulsion instead of water. The cores were buried for two years under forest, grass and clean cultivated soil.

It is unknown whether transplantation of bone marrow mesenchymal stem cells (BM-MSCs) can repair spinal cord ischemia-reperfusion injury (SCII) in a rat model through an anti-apoptotic effect. Adult rats were divided into untreated or sham-operate...
