Ephemeral gullies: to till or not to till?
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
While the perceived magnitude of ephemeral gully
erosion may be masked after gullies are repaired, the action
of plowing in these channels reduces topsoil thickness and
crop productivity over a much wider area than the ...
Ephemeral gully headcut development and migration in stratified soils
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
The objectives of the current study were: (1) to quantify
the effect of an erosion resistant (ER) soil layer placed at
various depths within a soil profile on headcut development
and migration; and (2) to assess the ...
AnnAGNPS ephemeral gully erosion simulation technology
(Universidad Pública de Navarra / Nafarroako Unibertsitate Publikoa, 2007)
info:eu-repo/semantics/conferenceObject,
Tillage-induced ephemeral gully erosion has been shown to
be a significant and sometimes dominant source of sediment
within a watershed. An approach has been developed within
AnnAGNPS to assess the impact of conservation ...
