Alkaline and saline–alkaline soils impose severe restrictions on plant growth. Panicum coloratum var. coloratum is a perennial C4 forage grass widely used in tropical and subtropical environments. Published information on ...

Aim: A major limitation to plant growth in acid soils is the prevalence of toxic Al3+. Most genotypic variation for acid soil-tolerance in wheat is linked with the Al3+-activated efflux of malate anions from roots which ...

There are plans to vegetate soil of the former lake Texcoco and use wastewater sludge to provide nutrients. However, the Texcoco soil is N depleted, so the amount of N available to the vegetation might be limited and the ...

Besides the ecological importance of extracellular proteases in the acquisition of nitrogen-rich organic compounds, these enzymes have also interesting biotechnological applications. Particularly, alkaline proteases represent ...

An investigation was made of the influence of alkaline extraction on the characteristics of humic substances extracted from Brazilian soil samples. Humic substances (HS) from seven different soils samples collected in ...

The Flooding Pampa is a plain, covering around 90,000 km2 composed of eolian and alluvial deposits. It is characterized by its geomorphology, with low (0.1–0.01%) slopes and elevations, including the coastal flat. A ...

Soil alkalinity is a significant limitation to agricultural productivity and it is associated to several soil features, among them, Fe deficiencies. In this work, we explored the hypothesis that alkalinity tolerance in ...
