The different nitrogen (N)

What nitrogen to use? Discover to better understand your cultures

The  fertilizer made available for indoor growers or growers outdoor are all different in their formulation (solid fertilizer solution of gaseous or liquid fertilizer) but especially by their different compositions, as shown explanations of nitrogen below. Understand to select your fertilizer so as to obtain the best results in your crops because the goal is that they are as abundant as possible.

Some fertilizers are composed of only one form of nitrogen. This is the case of the urea (100% N urea), anhydrous ammonia (100% NH 3 ) and potassium nitrate (100% nitric N).

But most fertilizers have mixed formulas. Their composition greatly influences the availability of nitrogen to crops. Indeed, the ammoniacal, nitric and ureic forms are transformed at variable speeds, determined by the microbiological activity of the soil.

The urea undergoes hydrolysis to take the ammoniacal form. The latter can be adsorbed and temporarily retained on the argilo-humic complex of the soil or used by the microorganisms of the soil which then compete with the plant.

The ammoniacal form can also rapidly evolve to the nitric form as soon as nitrification is active in a warm, aerated and moist soil.

The nitric form is completely released in the soil solution and preferentially feeds the plant.

What is organic nitrogen?

The organic nitrogen constitutes the major part of the nitrogen from the soil.

The organic nitrogen results from soil organic matter which aggregates which comes from crop residues and animal dung.

The organic nitrogen consists of various nitrogen compounds including mineralization is highly variable and very difficult to predict. Except some single technologies as Aminoweed 56 which contains 9% organic nitrogen 100% assimilable spray because normally organic nitrogen is also difficult to predict based on the level of absorption.

What is ureic nitrogen

It is a form of nitrogen that the soil does not retain.

It turns under the effect of hydrolysis in NH 4 + (ammonium) transformation which is accompanied by very significant losses through volatilization (gaseous loss of ammonia NH 3 ) up to 40%. In ordinary practice an average loss of 15% of nitrogen is to be expected.

The urea undergoes hydrolysis to take the ammoniacal form. This hydrolysis can be adsorbed and temporarily retained on the argilo-humic complex of the soil or used by the microorganisms of the soil which are then in competition with the plant.

The ammoniacal form can also rapidly evolve to the nitric form as soon as nitrification is active in a warm, aerated and moist soil.

The nitric form is completely released in the soil solution and preferentially feeds the plant.

Ammonium or ammonium nitrogen

It results from the combination of nitrogen (N) and hydrogen (H). Its chemical formula NH 4 + is very close to that of ammonia gas NH 3 which volatilizes into the air.

This processing is faster when the temperature increases and when the pH around the granule of fertilizer is greater than 7.5.

Thanks to its positive charge NH 4 + binds to the clay-humic complex of the soil, reducing the risk of training in depth but also instant availability to plants. The microbial activity of soils consumes ammonium and transforms it into nitric nitrogen, which is the process of nitrification.

Nitric nitrogen or nitrate

It is formed naturally by combining nitrogen (N) e

Fertilizers based on nitric nitrogen act quickly, while ammonium-based fertilizers have a slower action.

As for urea and cyanamide, they contain neither nitrate nor ammonium. The nitrogen they provide can not be directly absorbed by the plant. To make it assimilable, it must undergo processes of transformation.

The nitric form is completely released in the soil solution and preferentially feeds the plant.
