Suppression of nitrification in soil by a tropical grass
Country
Colombia
Description
[Synopsis]
In the nitrification process, ammonium-N is converted into nitrite-N and nitrite-N is converted into nitrate-N. If nitrification can be controlled, it is possible not only to increase the nitrogen absorption efficiency by plants but also to decrease nitrous oxide emission from soil.
It was found that a tropical grass, Brachiaria humidicola, suppressed multiplication of ammonium- oxidizing bacteria and suppressed the process in which ammonium-N was converted into nitrite-N.
By this function, nitrification in soil was suppressed and nitrous oxide emission from soil was remarkably decreased.
