What is the difference between prilled and granular fertiliser?

What is the difference between prilled and granular fertiliser?

Prills form smaller, more monodisperse particles, where no additives are needed. Granules on the other hand form bigger and stronger particles, which are more resistant to wear caused by transportation and can homogeneously be blended with other granules based on particle size.

What is prilled fertilizer?

Prilled is a term used in mining and manufacturing to refer to a product that has been pelletized. The pellets are a neater, simpler form for handling, with reduced dust. The material to be prilled must be in a solid state at room temperature and a low-viscosity liquid when melted.

How do you use prilled urea?

Application and Management On alkaline and close-to-neutral soils, urea must be embedded in the soil no later than 2 to 6 hours after application or applied directly to a depth of 4-6 inches. This will help reduce nitrogen losses in the form of ammonia as a result of hydrolysis and activity of urease soil enzymes.

Can urea and NPK be used together?

Stimulation by the fertilisers improved the DO level by 76, 75 and 77.8% respectively for wastewater treated with urea, NPK and a combination of both respectively. Generally, the best results were obtained when both fertilisers were used together.

What is the importance of Prilling of urea?

The prills formed a smaller and softer substance than other materials commonly used in fertilizer blends. Today, considerable urea is manufactured as granules. Granules are larger, harder and more resistant to moisture. As a result, granulated urea has become a more suitable material for fertilizer blends.

What is granular urea?

Granular urea, with a 46 percent nitrogen content, is a solid nitrogen fertilizer product. Produced from ammonia and carbon dioxide, it has the highest nitrogen content of any solid nitrogen fertilizer.

Can I mix urea and complete fertilizer?

Urea can be mixed with most other fertilizers but fertilizer mixtures containing urea should be applied immediately after mixing. Do not store fertilizer mixtures containing urea. Ammonium phosphates and super phosphates should not be mixed with lime, slag, rock phosphate or CAN.
