SOIL ACIDITY IS A NATURAL AND INDUCED CHEMICAL CONDITION OF SOILS THAT CAN:
•decrease the availability of essential nutrients;
•increase the impact of toxic elements;
•decrease plant production and water use;
•affect essential soil biological functions like nitrogenfixation; and
•make soil more vulnerable to soil structure decline and erosion.
•The process of soil acidification is a potentially serious land degradation

Spain’s “red river” is one of the most recognizable bodies of water in the country due to its
deep red color. Known as the birthplace of the Copper and Bronze Age and the origin of
Columbus’s 1492 expedition, its significance in history can’t be denied, but what caused
its crimson hue? Some say that 5,000 years of mining pollution has made the river’s waters
highly acidic (pH 1.7-2.5) and rich in heavy metals. However, the presence of chemolithotrophic
organisms in the water has led others to believe that iron-oxidizing bacteria and sulfur-oxidizing
bacteria are the true culprits. Whichever the case, Rio Tinto remains one of Spain’s marvelous
but perilously “un-swimmable” rivers.

Humic acid is especially beneficial in freeing up nutrients in the soil so that they are
made available to the plant as needed. For instance if an aluminum molecule is binded
with a phosphorus one, humic acid detaches them making the phosphorus available for
the plant. Humic acid is also especially important because of its ability to chelate
micronutrients increasing their bio-availability.
