There is further evidence to indicate that nitrogen applications on or near the surface tend to make earthworms feed and excrete their castings well below the surface.
Within days of a high nitrogen application, particularly on lawns, the green blades can be seen shooting forth.
The liquid nitrogen application usually takes less than a minute.
In France, the recommendation for the first nitrogen application on wheat is 6 weeks before Z30, with the second application on Z30.
ISNT represents an alternative approach to managing nitrogen application.
Excessive nitrogen application, however, appears to promote the rapid decomposition of organic matter in the soil, resulting in release of carbon dioxide.
Although CULTAN fertilization is only done for nitrogen application, injection irrigation can also be used for other types of fertilizers.
Turf growth at the time of nitrogen application has an impact on nitrate (NO3) leaching risk.
A highly soluble fertilizer, containing nitrogen in its nitrate form, such as ammonium nitrate, can create leaching three to seven times greater than United States Environmental Protection Agency (EPA) limits of (10 ppm) NO-N during a time of ten to twenty-five days following nitrogen application.
At 10 percent nitrogen by weight this would be a nitrogen application of 2 pounds per 1,000 square feet.
