Fertiliser
Products
Loongsyn’s fertiliser products are formulated to supply essential nutrients required by crops at different stages of growth.
Each range is developed with declared nutrient composition and practical field application in mind. These fertilisers are commonly used for oil palm, paddy, rubber, and other agricultural crops.

Our Promise to You
We do our best to ensure every bag contains the correct percentage of nutrients as declared. We do not use urea as our nitrogen source due to its volatility. Instead, we use non-volatile, ammoniacal nitrogen sources. For phosphorus, we use water-soluble phosphate (up to 80%) in selected series. We do not use coating or inert fillers, as they do not provide nutrient value to the crop.
Non-volatile Nitrogen
Nitrogen supplied in non-urea form.
Water-soluble Phosphorus
Used in selected Supreme, Raja, and Royal series formulations.
No Inert Filler
No filler materials added that do not contribute nutrient value.
