Nitrogen

NITROGEN


In order to understand Nitrogen fertilizers a quick back ground on the Nitrogen Cycle is in order.

Green is the major components of Nitrogen and where they exist in the environment.
1. 70% of the air we breathe is Nitrogen
2. Nitrogen is the component of Amino Acids.
3. Amino Acids are the building blocks of DNA.
4. DNA is the building blocks of protein.
5. DNA and protein are the building blocks of all life Plant and Animal
6. 10 ppm of nitrate in water makes it un drinkable..

Blue is the way Nitrogen gets into the different components.
1. Reduction is the process of taking on electrons in chemical terms.
2. Redox Potential is the ability to receive those electrons

Red is the way Nitrogen leaves the major components.
1. Oxidation is the loss of electrons in chemical terms
2. In order for Oxidation Reduction to occur Oxygen must be present and this is called an Aerobic reaction.
3. A reaction with out the presents of Oxygen is called Anaerobic reaction.



Now I am not a PhD or even an Agronomist. Therefore a full understanding of the Nitrogen Cycle is not necessary. I offer it only as a start to discussing Nitrogen Fertilizer. A simple knowledge of the Nitrogen Cycle will help us understand how our fertilizer works. I have been asked by members of this form to start this thread. PLEASE I NEED HELP. The only way it will work is with input from many others. I have tried to make the Nitrogen Cycle as simple as I could and I have and will make mistakes. Please feel free to correct me or help.

If Nitrogen is successful then we will discuss Phosphorus and the Potassium etc.

Nucleic Acids are building blocks of DNA
Amino Acids are building blocks of Protein

DNA holds all of the protein making information though for the RNA to come and copy to make more protein.

Ric,

I like your statement about

I think a working understanding of N will be important, and probably most important to N management is the forms that N exists in, that is the primary NO3- ion, and how this interacts with the CEC and AEC in soils, and the need for exact nitrogen management in lawns to prevent run-ff and pollution. We can compare N to P as it is held by the soil particles, its availability, and solubility, and this will help all of us, including me, to better understand the management of N.

I have been an agronomist for the past years and N management in crops is often the number one way to boost yields, so we know it must be crucial for excellent turf grass management as well. I hope to contribute and help with this thread, although much of my knowledge is biased in the way of row crops and forages, but I am happy to help.

Let's get it on...

EG

Ok Lets get it on. But let us keep it simple and then build.

70% of the air we breath is N. Lightning is an oxidizer. Therefore a Thunder storm will oxidize N and rain will have a small % of N in it.

What are some other ways N gets to our plants from the air???

Fertilizer is the last thing we will talk about in the Nitrogen cycle.

Thanks for the first of many corrections.

Big One: Nitrogen Fixation by legumes, possibly over 100 lbs/A from clover. Or, I mean 2.32 lbs per K.

A thunderstorm can produce about 0.4 lbs N per K as well, but is usually less. Does that sound right Ric? That's why things often seem green just after a thunderstorm I think.

As far as thunderstorms go the only data I have heard of claims New England gets about 0.5 lb N per K per year. The prof who gave this data said a good study for a Masters degree would be to do this in Florida. Florida is the Lightning capital of the USA.

Nitrogen Fixation by legumes is one of the big N sources. As a kid I lived in Penna. and my daddy planted Clover to help keep the lawn green. Do people still do this??? What is a legume and how does it make N ????

Legumes are noted for the relatively high protein content of their seed and high nitrogen concentration of vegetative parts. Apart from their distinguishing flower characteristics, legumes are also noted for their capacity to live symbiotically with bacteria in their roots, resulting in the fixation of atmospheric nitrogen by the Rhizobia for the plant use.

I think we are still at the 8th grade level. however hold your hat because with a little help we will get to Nitrifiction, Nitrosomonas, and Nitrobacter. And a whole bunch of other words you never heard of in high school.
