Soil acidification is the buildup of hydrogen cations, which reduces the soil pH. Chemically, this happens when a proton donor gets added to the soil. The donor can be an acid , such as nitric acid , sulfuric acid , or carbonic acid .
Global variation in soil pH. Red = acidic soil. Yellow = neutral soil. Blue = alkaline soil. Black = no data. Soil pH is a measure of the acidity or basicity (alkalinity) of a soil. Soil pH is a key characteristic that can be used to make informative analysis both qualitative and quantitatively regarding soil characteristics.
Freshwater acidification is primarily caused by sulfur oxides (SO x) and nitrogen oxides (NO x) entering the water from atmospheric depositions and soil leaching. [1] Carbonic acid and dissolved carbon dioxide can also enter freshwaters, in a similar manner associated with runoff, through carbon dioxide-rich soils. [1]
Acidification may refer to: Ocean acidification, decrease in the pH of the Earth's oceans; Freshwater acidification, atmospheric depositions and soil leaching of SOx and NOx; Soil acidification, buildup of hydrogen cations, which reduces the soil pH; Souring, a cooking technique
Soils become acidic in several ways. Locations that have high rainfall levels become acidic through leaching. Land used for crop and livestock purposes loses minerals over time by crop removal and becomes acidic. [5] The application of modern chemical fertilizers is a major contributor to soil acid by the process in which the plant nutrients ...
The soil of your lemon tree needs acidity, too. "Lemons do best with slightly acidic soil, so use a fertilizer specifically for acid-loving plants," says Irish-Hanson. She recommends using the ...
Soil Preparation: If aeration is on your to-do list, do it before applying pre-emergents to avoid disrupting the herbicide barrier. Safety: Suit up with gloves, long sleeves, and eye protection ...
Soil acidification is beneficial in the case of alkaline soils, but it degrades land when it lowers crop productivity, soil biological activity and increases soil vulnerability to contamination and erosion. Soils are initially acid and remain such when their parent materials are low in basic cations (calcium, magnesium, potassium and sodium).
