Urea – Nitrogen booster for your plants


Your complete organic source for nitrogen !

Urea has been widely used as a single source of nitrogen (N). CO(NH2)2, purity > 98%

600g of urea will yield 280ppm of Nitrogen

1kg of Urea will yield 467ppm of Nitrogen

Density : 1.32g/cm3


NPK ratio of 46-0-0

SKU: N/A Category:

Application techniques :

Method I :

For trees & shrubs, scatter 30cm away from the stem

– wet the soil before apply

– till the soil and mix well

About one tablespoon per 8″ diameter pot. Apply one per month.


Method 2 :

Dissolve in water and water once weekly.


For most adult plants, 25-40ppm of N is sufficient.

For young plants, require just half the amount.


Application note :

Dissolve 300g of urea in 1000 litres of water to get 140ppm (3g into 10 litres of water).

Water your plants as per normal, use once every week.

Use ratio to get the correct amount of urea with the amount of water you plan to use.


Work example :

Q1: You just have a 4 litres watering can. How much urea to use ?

Ans : Knowing that 60g of urea needs 1000 litres of water to dilute, for 4 litres, we just need 60 x 4 / 1000 = 240mg of Urea to get 28ppm.


Q2: I need 40ppm of N. How much Urea to use ?

Ans : 40 / 0.45 = 89mg of Urea. Thus dissolve 89mg of urea in 1 litres of water will get you 40ppm, or 89 x 4 = 356mg of Urea in 4 litres of water (your measuring can volume) to yield 40ppm of N.


Q3 : What’s the typical ppm I should be using ?

Ans: 230ppm of N is a good number to use. This translated to using 500g of urea into 1000 litres, which is equal to dissolving 5 g of Urea into 10 litres water.


Note that 240mg is NOT 240 ml nor 240cc…. there is something call density :~)
