Urea is the most important nitrogen fertilizer on the market, containing the highest percentage of nitrogen (about 46 percent).
It is a white crystalline organic chemical compound. Urea is pH neutral and can adapt to almost all soil types.
It is a waste product formed naturally by protein metabolism in humans as well as mammals, amphibians, and some fish. Urea is widely used in the agricultural sector as a fertilizer and feed additive.
The main function of urea fertilizer is to provide plants with nitrogen to promote green leaf growth and make plants look lush.
Urea also aids in the photosynthesis of plants. Since urea fertilizer can only provide nitrogen and not phosphorus or potassium, it is mainly used for flowering growth.
Advantages of urea fertilizer Superior nitrogen content
Low production cost as the source is natural Non-flammable and hazard free storage
Wide application range for all kinds of crops and soil pH neutral and harmless to crops and soil
Phosphate fertilizer is a natural source of phosphorus, and it is a fertilizer that provides a quarter of the nutrients needed by plants for their growth and development. It is mentioned that phosphate fertilizer consists mainly of phosphates; Which is formed after processing phosphate rock to produce phosphorus, and phosphorus is one of the three main nutrients most used in fertilizers.
Types of phosphate fertilizers
There are many types of phosphate fertilizers, some of which are liquid and some are dry; The way plants benefit from phosphorous is not affected by liquid or dry fertilizers, but the factors for choosing one of the types of these fertilizers depend on the following factors:
application method. Crop type.
According to the soil test. climatic conditions.
It is also known as “farm manure”, and it is a mixture made of animal waste, plant residues, or animal waste and plant residues together, so it is rich in nature’s ingredients, and examples of it are (bird poop, ground bone, crushed shells, wood, blood powdered dried), and it is difficult for the plant to benefit directly from the elements present in the organic fertilizer, as it is necessary for the intervention of microorganisms that analyze these wastes and liberate their elements in order for the plant to absorb and benefit from them.
Types of organic fertilizer
– Plant organic fertilizer
– animal organic fertilizers
– organic mineral fertilizers
