Volcanic soils are extremely productive thanks to their particular characteristics. Therefore, even though they represent <1% of the soils worldwide, they are very important for global and local agriculture, as they account for >60% of the arable land of Chile. However, studies evaluating their soil quality are still scarce. Subsequently, soil quality indicators have not yet been established...
The unique features of Andisols differentiate them from other soils and influence their management and use, which should be specific for each soil within the general concept of Andisols. Since it is difficult to determine the type and amount of clay in these soils, validating simple, cheap, fast methods capable of differentiating among volcanic soils is essential for site-specific management. Thus,...
Considering the importance of acidic conditions and Al toxicity in arable soils of Chile, 2 field experiments were conducted in the 2005-06 and 2006-07 growing seasons in Valdivia (39°47′18′′S, 73°14′05′′W), Chile in an Andisol. The objective of this experiment was to quantitatively evaluate the effect of different soil exchangeable Al levels on grain yield, and above-ground and root biomass of Al-tolerant...
