RCF produces two grades of complex fertilizers at its Trombay unit. They are commonly known as Suphala which has almost become a generic name for NP/NPK complexes in the farming households of the country.

 Suphala 15:15:15

Suphala 15:15:15(also called S15) is a unique complex, granular, natural color fertilizer

The major plant nutrients, Nitrogen, Phosphorus & Potash are present in equal proportion(15% each). Homogeneous granules keep the nutrients in exact proportion and assure even available to the individual plants. The absorption of each nutrient is enhanced by the presence of other nutrients.

The granules are spherical, uniform(2 to 4 mm in size), and free-flowing, which facilitates their uniform application to the soil.

S15 can be easily applied by seed drill. Due to their density, the granules are not blown away by wind or mechanically washed out by irrigation water.

On application of Suphala 15:15:15, the readily available forms of nutrients like nitrate nitrogen, water-soluble phosphate, and potash are immediately available to the crops. This helps in establishing strong roots and promotes desired growth of the crops in the early stages.

The other forms of nutrients like ammonical nitrogen, citrate-soluble phosphate and temporarily held potash in Suphala keep the nutrients available to the soils for a longer period. These nutrients are released gradually which assures high nutrient status in the soil for a longer period and thereby ensures healthy and luxuriant growth of the crops.

Suphala 15:15:15 also contains secondary plant nutrients like Calcium, Magnesium, and Sulphur which are helpful for the improvement of the soil and also facilitate the efficient uptake of other nutrients by the plants.

This product has found wide acceptance in the cultivation of cash crops like sugarcane, cotton, and jute, as well as fruit crops. It is extremely effective in improving the yield of plantation crops like tea and coffee.

Suphala 15:15:15 is packed in a 50 kg golden yellow colored bag which is available with the authorized dealers of the RCF throughout the country.

Field trials on various crops in varied climatic conditions and different types of soil have proved the usefulness of this product in short and long-duration crops.

It is a concentrated fertilizer containing plant nutrients in chemical combinations which reduces the cost of application, transportation, handling, and storage.

Suphala leaves a residual effect in the soil which is beneficial to all crops.
