Urea fertilizer application on Cold Soils.
I recently came across an article that discusses urea application on cold soils. These studieswere conducted in Montana by Rick Engel and Clain Jones through the Department of Land Resourcesand Environmental Sciences at Montana State University. With the price of f ertilizer, some of you maywant to change how and when you apply your fertilizer. Urea broadcast from mid-fall to early spring onsoils at or near fr eezing was historically considered fairly safe from ammonia loss to the atmosphere,termed volatilization. Not so, according to recent research in Montana. Engel and Jones found that up to44% of urea surface broadcast between October and April was lost to volatilization.
The three year study measured ammonia volatilization loss from surface-applied urea and ureaamended with a urease inhibitor designed to decrease volatilization on producers’ fields in southwest,central and north central Montana. In 8 of 13 field trials, peak urea volatilization loss occurred when soilsurface temperatures were below 41°F. Cumulative ammonia losses from urea varied, but averaged
about 20% of applied nitrogen.Surface soil moisture was a major contributor to overwinter urea volatilization on these fields. The
largest nitrogen losses (30-44%) occurred when surface applications were made to moist soils followedby at least 2 weeks with no or little precipitation (less t han 0.2 inches). Even when the soil surface wasfrozen at the time of application, volatilization losses were high. In one trial, urea was applied on January27 to a calcareous soil covered with approximately 5 inches of snow. As the snowpack disappeared, theammonia losses picked up and peaked 5 weeks after application. By early April, 24% of the appliednitrogen had been lost.
The lowest nitrogen losses (<10%) occurred when urea was broadcast on dry soil followed by atleast ¾-inch rainfall. Light rainfall (<1/3-inch) on dry soil resulted in nitrogen losses of 10-20%. Ureabroadcast on dry soils should have at least ½-inch of rain or irrigation in one event to move urea deepenough into the soil to minimize volatilization and yield reductions associated with nitrogen loss.If a producer wants to make an application onto cold soils, Urease inhibitors can be used. They are oneclass of chemical compounds that can be added to urea fertilizers to inhibit transformation to ammoniumand ammonia. The most common urease inhibitor is N-(n-butyl) thiophosphoric triamide (NBPT), used inAgrotain®. NBPT can reduce ammonia volatilization for 2 to 10 weeks. In general, its longevity declinesas soil temperature and moisture content increase. In this study, coating urea with NBPT (0.1% byweight) reduced cumulative ammonia losses by about 2/3. Volatilization protection lasted 2-3 weeks onacidic soils (pH 5.5-6.5), and more t han 7 weeks on an alkaline soil (pH 8.4).
This study demonstrated that significant ammonia losses f rom surface-applied urea can occurduring cold weather months. Ideally, broadcast urea should be incorporated by tillage, rainfall or irrigation.Coating urea with NBPT can help protect surface applied urea for several weeks to allow time forincorporation by tillage or by at least ½-inch of water in one event. An alternative for dry land no-tillproducers who do not want to rely on unpredictable rain events is to double-shoot, or sub-surface band,urea into the soil at seeding.

The 310 Permit applications are also
available on the Powell County
website. It is a link to the DNRC that
will give you instructions as well as a
fill-in 310 form to submit to the
Conservation District.
A 310 permit is REQUIRED if you
are planning ANY project that
physically alters or modifies the bed
or banks of a stream. The purpose of
the permit is to minimize soil erosion
and sedimentation, protect and
preserve streams and rivers in theirnatural or existing state, and to
prevent damage to the lands and
property immediately adjacent to
streams and rivers.
