Aluminum toxicity limits plant growth in acid soils. Because of their advanced state of weathering, acid soils of the tropics also tend to be deficient in nutrients. A realistic assessment of plant adaptation to these soils would therefore require Al-toxic conditions under which growth is simulta...
Phosphorus (P) deficiency and aluminium (Al) toxicity are widespread in Oxisols of the tropical savannas of eastern Colombia. A field experiment was conducted to determine the effect of Al toxicity and P deficiency on plant growth and nutrient uptake of two Brachiaria species. To examine the infl...
