Variability of Soil Types in Wetland Meadows in the South of the Chilean Patagonia

The wetland meadows and pastures (vegas) of the agricultural zone of the Magallanes Region and the Chilean Patagonia are productive and intensively exploited ecosystems. However, there is scarce data about the typology and the physical and chemical properties of the soils that determine the agricult...

Analyses of bulk and particle densities, capillary water capacity, pH (H2O), pH (CaCl2), texture, organic material, C:N ratio, electrical conductivity, effective cation exchange capacity, N, P, Ca-Mg-K-Na, exchangeable Al, extractable Al, sulfur SO4(2-), B, and micronutrients (Cu-Zn-Mn-Fe) were carried out.
