Soil erosion in three grazed plant communities in northeastern Patagonia
(John Wiley & Sons Ltd, 2014-03)
Grazing has been identified as the main cause of land degradation in Patagonia. However, land degradation is highly variable among areas, even within the same paddock. This strongly suggests that different plant communities ...

Soil-geomorphology relationships and landscape evolution in a southwestern Atlantic tidal salt marsh in Patagonia, Argentina
(Pergamon-Elsevier Science Ltd, 2018-07)
Salt marshes in Patagonia ecosystem are nowadays fully recognized by ecological, pollution and phytoremediation studies but a soil genesis and geomorphology approach is currently unknown. The aim of this study was to ...
Measurement of metal-complexing ability of polyfunctional macromolecules: a discussion of the relationship between the metal-complexing properties of extracted soil organic matter and soil genesis and plant nutrition
(The Williams & Wilkins Co., 1975)
Characterization of the metal-complexing ability of polyfunctional macromolecules through the determination of stability constants of their metalic complexes is discussed along with the validity of ascribing a relationship ...
Soil fertility shapes fire activity across Mediterranean-type climate regions
(Wiley, 2023)
Aim:To quantify the role of soil fertility in the spatial variability of fire activity and to identify the mechanisms that drive this variability. Location:The five Mediterranean-type climate regions of the world.Time ...
Seed weight predicts seedling emergence, and extremely acid soil and low availability of Phosphorus are associated with poor plant performances in Lepidium meyenii Walpers (maca)
(Elsevier, 2019)
Lepidium meyenii Walpers (maca)is a Peruvian species cultivated in the high Andean region (ca. 4000 m.a.s.l.), highly praised for the nutritional properties of its hypocotyl. The benefits to human health and their relationship ...
Soil phosphorus extracted by Bray 1 and Mehlich 3 soil tests as affected by the soil/solution ratio in Mollisols
(Taylor, 2011-01)
Different relationships between soil-test methods results have been reported in several agricultural regions. Differences in the same soil-test procedure (e.g., soil/solution ratio) exist between soil-testing laboratories ...
