Which consequence results from excessive soil acidity prevalent in some areas during early maize cultivation terraces?

💡 Explanation

When soil acidity is high, phosphate ions become less available because they bind to aluminum and iron oxides prevalent at low pH, reducing plant uptake. Therefore reduced phosphate absorption by roots results, rather than increased nitrogen fixation, enhanced potassium uptake, or greater water retention, which are favored by neutral or alkaline conditions.
