Figure 3.
A similar pattern to Ca2+ was obtained with
Mg2+ content, recording values categorised as low
(< 0.5meq 100 s-1) in most uses for both
depths. It should be noted that the nutrient content, such as available
P and Exchangeable bases, were lowest in the forest land use, reflecting
the nature of these soils and illustrating their limited contribution to
quality (Bravo, RamÃrez, et al., 2017).
The available Zn content was significantly higher (p<0.05) at
0-10 cm deep (Figure 3e). The chakras (A, B, C) recorded higher values
than the rest of the uses, ranging from 2.84 to 0.76 mg
kg-1, with a similar pattern for the subsurface layer
(10-30cm). Available Zn concentrations <3mg
kg-1 have been indicated as critical, therefore, the
values obtained ranged from medium to low levels. Finally, leaf litter
production (Figure 3f) varied significantly (p<0.05) according
to land use, defining three groups. The first group of values ranged
from 8 to 10Mg ha-1 and included the forest and two
livestock systems (Cattle_B and _C), the second group had values close
to 4Mg ha-1 and comprised Chakra_A and Cattle_A, and
the third group was Chakra_A and _C with values between 2 and 4Mg
ha-1.
