5
15
25
35
Which of the following factors impact nitrification?
Population of nitrifying bacteria
Soil Temperature
Moisture
Soil pH
All of the above
Why does the ammonium form of nitrogen remain at the root zone?
Positively Charged
Negatively Charged
Denitrification
High Temperatures
Over 35 years of university trials demonstrated a _____% yield advantage to using N-Serve with anhyrous ammonia
0-2
3-4
5-7
8-9
How do I determine the amount of N-Serve I apply?
Depends on the amount of Nitrogen applied
Always 32 ounces per acre
Always more than 50 ounces per acre
Always close your eyes and guess on the amount
Why does fall applied N-Serve and anhydrous ammonia still work in the spring?
Magic
90 day period of effectiveness does not start until soils are warmer than 40*
Nitrogen does not leech until the spring regardless of the soil temp
Use N-Serve to ensure you have an adequate nitrogen supply, which allows for the following benefit(s) in the corn crop. Select all that apply
Greater standibility
Heavier test weight
Higher protein content
Lower moisture content
DCD is _______ and can leach away with the first significant rain.
Water Soluble
Water insoluble
Oil
Nitrapyrin is ____________, remaining in the root zone protecting your nitrogen from losses due to rain/water.
Water Soluble
Water insoluble
Oil
___________is the only nitrogen stabilizers proven to optimize yield potential of corn when used with anhydrous ammonia
Instinct
N-Zone
Centuro
N-Serve
Environmental benefits of using N-Serve include
Increased soil nitrogen retention by 28%
Decreased nitrogen leaching by 16%
Decreased Greenhouse emissions by 51%
All of the above
N-Serve and Instinct both work by ___________
Adding additional nitrogen to the soil
Slowing down the population of bacteria that converts nitrogen to nitrate
Keeps nitrogen in the form of nitrate
Allows nitrogen to burrow and hide deeper in the soil that it would naturally
N-Serve protects nitrogen underground, where up to __ of nitrogen loss can occur.
40%
50%
60%
70%
