The global agricultural sector needs to implement good soil management practices, in particular prevent erosion and improve water-retention capacity. introduction of tillage techniques along theoretical lines, called keylines, can make a significant contribution improving the crops. keyline system has been around for less than 100 years. With this preliminary work, we performed comparative anal...
The piñon (Pinus edulis Engelm.)-juniper [Juniperus monosperma (Engelm.) Sarg.] woodlands of Bandelier National Monument are experiencing accelerated erosion. Earlier studies suggest that causes of these rapidly eroding woodlands are related to an unprecedented rapid transition of ponderosa pine (Pinus ponderosa C. Lawson) savanna to piñon-juniper woodlands as a result of cumulative historical ...
Soil erosion is a complex phenomenon which combines the deterioration of their surface layers and the movement of the eroded materials that make it up. It is a constant issue for foresters, in particular in the management of new or restored forests. In metropolitan France, we spontaneously think about the restoration of mountain terrains (RTM), implemented from 1860 to stabilise degraded mounta...
OBJECTIVE While gingivitis and caries continue to be prevalent issues, there is growing concern about dental erosion induced by dietary acids. An oral hygiene product that protects against all these conditions would be beneficial. This study investigated the potential of two anti-erosion dentifrices to inhibit plaque. METHODS This was a randomized, three-period, two-treatment, double-blind, c...
