NON-GREEN MANUAL & FERTILIZER(UREA):

Urea or carbamide is an organic compound with the chemical formula CO(NH2)2. The molecule has two —NH2 groups joined by a carbonyl (C=O) functional group.it is used in the agriculture field which as many effect in the

environment.

It is common that urea is used as an fertilizing agent in the field of agriculture but when the quantity of urea increases it results in unfertile land, damaging crops etc. ,are some of the common problems but there are other problems that people

are not aware off.

The farming field which is fertilized with urea helps the plants grow but if the urea passes to the water source (remaining water from the field) it results in the growth of the blue green algae which is also termed as cyanobacteria.

Cyanobacteria/ blue green algae

The blue green algae will depletion(reduce) oxygen in the water which affects marine life , due to such causes the fishes to suffer breathing and as a result they will die due to less oxygen

Causes of blue green algae in sea plants:

The source of oxygen is obtained from the sea plants is the only

source of oxygen.When the algae grows fully they

cover the surface of the sea forming a coat in the water which blocks the

sunlight

It is difficult for the plants to get sunlight as the algae forms a layer above the water.The result is that the plants can not survival with out sunlight .

The presence of toxic blue-green algae blooms in lakes has become a commonly recognised phenomena in the summer time but scientists have discovered that exposure to cyanobacteria may have another long term effect on wildlife.

Because of the dangers associated with saline methods, other instillation methods such as hypersomolar urea are sometimes employed,  though these are less effective and usually must be supplemented by oxytocin or a prostaglandin in order to achieve the desired result.

Urea abortion

Incomplete or failed abortion remains a problem with urea methods, often precipitating the additional risk of surgery

As with other instillation techniques, gastrointestinal side effects such as nausea or vomiting are frequent,

but the most common problem with second trimester techniques is cervical injuries, which range from small lacerations to complete detachments of the anterior or posterior cervix. Between 1% and 2% of patients

using urea must be hospitalized for treatment of endometritis, an infection of the lining oft he uterus

These diseases include:Argininosuccinic aciduriaArginase deficiencyCarbamyl phosphate synthetase (CPS) deficiencyCitrullinemiaN-acetyl glutamate synthetase deficiency (NAGS)Ornithine transcarbamylase deficiency (OTC)As a group, these disorders occur in 1 in 30,000 newborns

Problems of urea :Urea can be irritating to skin, eyes, and the respiratory

tract. Repeated or prolonged contact with urea in fertilizer form on the skin may cause dermatitis.

Urea can cause algal blooms to produce toxins, and its presence in the runoff from fertilized land may play a role in

the increase of toxic blooms

High concentrations in the blood can be damaging. Ingestion of low concentrations of urea, such as are found in typical human urine, are not dangerous with additional water ingestion within a reasonable time-frame. Many animals (e.g., dogs) have a much more concentrated urine and it contains a higher urea amount than normal human urine; this can prove dangerous as a source of liquids for consumption in a life-threatening situation (such as in a desert).
