Know about Urea fertiliser

Urea- The white, crystalline solid comprises of a proportionate compound mixture of more than one nutrients and contains 46% nitrogen. Farmers have identified with this chemical fertilizer as a great ladder to huge success in agro revolution.

Chemical Introduction

Urea is identified as an organic compound in the worldwide. Urea is known worldwide by a variety of names like carbonic resin, carbonyl diamide, and carbonyldiamine.

Urea is a soluble compound and easily gets along with water. The chemical structure of urea helps it to be soluble enough as the hydrogen bonds with water molecules, each forming two bonds with oxygen. The planar structure further enhances its astonishing molecular point symmetry. Commercially it is manufactured with the help of ammonia and carbon dioxide.

Agricultural usage--

Extensively used as a chemical fertilizer, urea releases nitrogen into soil which is thereafter taken in by the plants.

On a commercial basis, urea is available as prills or as a granulated fertilizer. The large granules are crystalline white and are highly resistant to moisture and thus facilitate long time storage as well. Today these granular shaped crystals of urea are blended with most of the fertilizers.

 Urea operates in the soil When applied as a foliar spray or even as granular spread above the soil layer, urea gets dissolved simultaneously owing to its reaction with air and water.

When properly applied, urea results in effective crop yields as it is an excellent source of nitrogen and nitrogenous compounds.

Once applied to the soil, urea undergoes vital transformations and breaks up into ammonium form and this total process is dependent on soil moisture.
As soon as urea dissolves in the soil, it forms around it a  layer of high pH and ammonia concentration turning the soil to be acidic and toxic at the same level. Though most of the soil types kill the toxicity by making it neutral.

Taking into effect all these effects it is highly advisable to broadcast urea immediately into the soil and should be kept at a distance from the seeds.

Keep an alert while applying so as to urea fertilizer should not touch the seeds. And especially the corn seeds should never be placed with urea and its components.

Application of Urea
Urea can be applied in various forms, it can be spread in bulk alone or can also be mixed with other fertilizers before application.

However Urea should be preferably spread alone so as to avoid unevenness in the field.

If Preparing blended mixtures with other fertilizers the best ones to suit its density are monoammonium phosphate (11-52-0) or diammonium phosphate (18-46-0). When blended together, these are easily spread uniformly across the cultivated land.

Advantages of Urea Fertilizer
When applied in measured proportions and through precise methodology, urea works wonder for all crops and increase 4times  the yields by great proportions.

As urea comprises of 46% N, it can be easily stored, transported and handled safely. There are no explosion hazards caused by urea fertilizer

The nutrient composition rendered by urea enhances the productivity of the soil and enriches its nutrient constituency. Providing each plant with relevant elements needed, urea sustains plant life.

Disadvantages-
Urea releases harmful pollutants during its manufacturing process. The manufacturing involves emission of pollutant gases in the air.

It exerts higher concentrations of ammonia in the soil making it even more acidic and thus retards the soil of its natural fertility.
