Variación espacial de la movilidad de Fe, Mn, Cu y Zn
(Universidade da Coruña, 1995)
[Abstract] To investigate the spatial behavior of topsoil Fe, Mn, Cu and Zn in a small
(1,8 ha) field 53 samples were taken acording to a nested sampling pattern. Metal contents extracted by 0.05 EDTA, both at pH = S and ...
Compacidad de los suelos desarrollados sobre sedimentos Terciario-Cuaternarios en Terra Cha (Lugo)
(Universidade da Coruña, 1997)
[Abstract] Using a gamma probe, bulk density has been measured for nine profiles from 20 cm depth to depths ranging from 90 to 15Ocm. The intent ofthis work was to assesss total porosity variability withinand between sites ...
Relación entre textura, pH, materia orgánica y complejo de cambio en el horizonte superior de un suelo sobre serpentinas
