As soon as urea dissolves in the soil, it forms around it a zoning 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.W
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.
In case of 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 increase4s 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.
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.
During storage, make sure that it is never stored in the vicinities of ammonium nitrate.
Never use small, fast-moving augers to move the urea.
- Maximum width for application of urea should be 50 feet and not more than that.
- Keep away from corn seeds and never enhance their direct contact as the results are not favorable.
- When urea is applied on acidic soils of higher pH i.e above 7.5, it should be incorporated into the soil as soon as possible.
- Urea is a high moisture absorbent therefore it should be stored in sealed and well enclosed bags.
- Avoid direct contact with urea fertilizer as it may prove to be hazardous to skin and when inhaled might cause severe allergic reactions.
