Unformatted text preview: occurs when the soil is saturated and the bacteria
use nitrate as an oxygen source.
NO3nitrate NO2nitrite NO
oxide Crop Uptake is the prime goal of N management
on farms. The greatest efficiency occurs when
adequate N is applied at a time when the crop is
actively taking it up. Efficient N use also depends on
a number of other factors including temperature,
soil moisture, pest pressure, and soil compaction.
In the moist Northeast climate, nitrate remaining
in the soil after the growing season will be lost to
leaching or denitrification between crop harvest
and the next planting season.
Efficient N use during the growing season and the
use of cover crops can minimize such losses. N2
gas De-nitrification is common in poorly drained soils.
