How can too much ammonium fertilizers turn the soil acid? As the ammonium-N in fertilizers undergoes nitrification (conversion of ammonium to nitrate in soils by bacteria), hydrogen (H+) is released, which can increase acidity. As the percentage of ammonium increases in a given fertilizer the acidifying potential will also be increased, thus reducing pH.
Can fertilizers cause soil to become too acidic? The use of fertilizers, especially those supplying nitrogen, has often been blamed as a cause of soil acidity. Acidity is produced when ammonium containing materials are transformed to nitrate in the soil. The more ammoniacal nitrogen fertilizer is applied, the more acidic the soil gets.
How does ammonium affect soil pH? Plants can take up N in two forms: ammonium and nitrate. Ammonium (NH4+) is positively charged, while nitrate (NO3–) is negatively charged. … As a result, the net effect of taking up nitrate-N is to increase soil pH around root zones; taking up ammonium-N reduces rhizosphere soil pH.
How does ammonium affect soil? After a release of ammonia the vapors will dissipate reacting with the moisture in the air to form ammonium and eventually return to earth in rainfall. Ammonium then quickly binds to the negatively charged soil organic matter and soil clays.
