Sinusoidal Flow Explained

Guy Swanson Discusses Sinusoidal Flow VIDEO

Something you did not know about NH3.  Look inside the nutrient band.
Aqua Ammonia 20-0-0 application as compared to pressure reducing NH3 application 82-0-0 has always been a mystery.
Aqua Ammonia applicators in the PNW and California apply about 30% to 40% less N and produce similar yields. Why?
It is not the manifold accuracy so much...It is not always the change in bulk density of the NH3.  Test plots prove that even with high accuracy pressure reducing NH3 manifold systems using freezing delivery lines.... high nitrogen performance cannot be achieved.... Exactrix is always much better at considerably lower rates of applied NH3.
The major difference of the application technique is the liquid stream flow of Aqua Ammonia....no hot spots....no globs....no steady by jerks application. The Aqua Ammonia stream flow can be targeted and low tillage openers can be used.
Remember NH3 is 100 times more concentrated as a liquid than as a gas. Pressure reducing NH3 systems deliver globs of 100 times more concentrated liquid.  The band has passages of gas state NH3.  This is one reason why producers must wait a good deal of time before planting.

The enclosed article also applies to Urea......steady by jerks application. Urea must be liquefied to provide better performance and a lineal uniform band. Not an easy task since Urea alone as a liquid drops to very low analysis of about 21% and salts at 60 degrees F...and AN added to urea increases the chance of loss to environment with mobile nitrate.  UAN and URAN has no pH shift so micro-nutrient availability is reduced.
Plus the nitrate assimilation by the plant is a two step operation to form amino acids.  The crop prefers NH3.  This is why starter fertilizers never use a nitrate based nitrogen source. Ammonic nitrogen is preferred by all commodity crops.
The lineal concentration of the nutrient band is the major key in Exactrix Pressure Increasing liquid delivery of NH3.
Time proven in test plot after test plot....Exactrix liquid NH3 is superior over any other approach.....Along with the pH shift of the applied NH4 band of 9.5 to 6.5..... freeing up critical micro-nutrients....NH3 is always the winner.
Sinusoidal flow can also be illustrated with squeeze pumps delivering 10-34-0 to the seed row....resulting in damaged corn seed and poor germination due to concentrated hot spots in the 30" seed rows.  Steady by jerks application allows the per acre rate to be achieved....the band rate is achieved....but the lineal band uniformity is poor to exceptionally bad resulting in lost yield.  This is why squeeze pumps should never be used to deliver APP to the seed row.
Now you can understand the rest of the story.  The competitive advantage is with Exactrix NH3.
Sinusoidal Flow of NH3, gas and liquid state results in "lost nitrogen". Exactrix builds a uniform lineal liquid band for immediate plant hair root access.
Single disc openers do build better plant useable NH3 bands since less area is disturbed.
Shank openers build poor bands with 8 times more soil disturbed area.
Less damage to the soil microflora occurs with Exactrix single disc opener application.
Exactrix bands remain more stable due to band size or exposed surface area.
Remember....Corn, wheat and barley are commodity crops that absolutely prefer ammonic state nitrogen.....not nitrate and not non-converted urea.
Urea can never be delivered uniformly whether surface or band applied.  The band variations of urea applications are seldom competitive when compared to Aqua Ammonia 20-0-0 or Exactrix Liquid NH3, 82-0-0.
The band of urea, 46-0-0 can only be improved if the urea is liquefied into a low analysis liquid solution.
The liquid fertilizer salesman said, "My more expensive liquid fertilizer is more crop available"......Wrong and Right at the same time. 

What the liquid fertilizer salesman forgot to say as properly corrected by scientist....."There is no difference in the crop availability of placed nutrients when comparing such materials as liquid APP, 10-34-0 and dry MAP, 11-52-0.  The advantage of my liquid fertilizer is that it can be more uniformly applied and therefore less is required to get the same results".  But why would the dealer want to sell less and get paid less?  The fertilizer salesman wants to sell "Tons" because he is on commission with a high margin product. So the P application rate generally remains the same at 25% more cost to the producer. 
Yes it is true.....the fertilizer salesman was right in a certain respect but the fertilizer salesman did not explain that uniformity of application makes the liquid APP more available.... not the chemistry.  Also the position or geometric location to the plant root system makes the biggest difference.....geometric location of the band to the seed row is a machinery issue just like uniformity of application is a machinery issue. The fertilizer dealer can not control the application machinery. The producer is in charge of machine and the management.....  controlling the application uniformity, the timing and TAPPS chemistry.
NASD/SEC regulated Stock Brokers are dropped from the business for not putting the investor client first.....so regulation of the fertilizer industry is imminent since so many producers are "too soon, too late, too smart". You might want to avoid a commission fertilizer salesman....always work with an independent agronomist that puts your interests first.
One exception regarding chemical nutrient availability is the use of Micro-nutrients which when properly mixed with APP....the liquid Micro-nutrients are more crop available than dry forms of micro-nutrients or other liquid P forms. Zn is an outstanding example.  Dry forms segregate at the mixing and delivery to the band and other types liquid phosphate (Ortho Phosphate 11-24-0, green acid) reduce the effectiveness of Zn as compared to APP.
Do not forget that Aqua Ammonia application always outperforms pressure reducing NH3 application on Yielder Drills.  Aqua Ammonia equipped drills will produce the same crop yield with 30% less nitrogen applied as compared to the NH3 drill.  Drills set up to apply dry Urea Vs pressure reducing NH3 are a push......Prior to Exactrix application of NH3....if the producer wants top yields and lowest cost and would like to stop and fill every 15 acres Aqua Ammonia is the winner.  Aqua Ammonia is traditionally applied with a flooded manifold using orifice plates with a 6% to 10% CV and.....there is no Sinusoidal Flow with liquid Aqua Ammonia.
Now you understand the rest of the story....reducing and stopping Sinusoidal Flow is a very key point in making nitrogen work better.
