How Coloring Agents Improve Technical Properties of Fertilizers

When it comes to the fertiliser game, what colour is it is not the first thought that many would have. But there is a reason why coloring agents for fertilizers are actually a thing — and it is not just for the aesthetics. In fact, they actively improve the way the product performs.

Have trouble believing what you just read? Don't worry; just keep reading to understand the many technical advantages these colouring agents provide. But first, let’s talk about why colours are actually used in fertilisers.

Why They Are Used

While coloured fertilisers are certainly more visually distinct, this is not the real value that they bring to the table. The real benefit of them is through their functionality — especially for manufacturers & distributors. How? Well, they help differentiate between multiple blends, grades & nutrient types. This might not seem that important at first, but it actually plays a vital role in the process.

Still not sure? Well, let’s take a look at the example of a Urea-based fertiliser. Now, most urea would be white when just produced. On the other hand, the NPK blend could be red or green, depending on the other fertimlizer types mixed in the blend. What this does is it allows the fertilizer handlers even end-users to instantly identify the product. Typically, when urea and sulfur are in a blend, a yellow hue is imparted, marking the addition of sulfur. 

Technical Benefits of These Agents

Now that we have talked about the major benefits from these colouring agents, it is time for us to pivot to some technical benefits as well. After all, the benefits of these agents go well beyond just the identification. Many of these are even used as part of advanced fertiliser coating technology. The advanced coating agents provided by NAQ Global also incorporate dust control and caking control abilities in the coloring formulations. 

When these coloured agents are applied to granules, the result is a significant improvement in flowability. What does this mean? It means that fertilisers are easier to handle & spread.

The agents are especially helpful in humid or high-moisture conditions. How? Because in these conditions fertilisers easily get clumped together. Now what these agents do is they form a barrier that keeps particles separate & free flowing. The result? Smooth application and consistent dosage.

Another benefit of these is the reduction of dust formation because of their usage. It is quite useful as otherwise it can lead to product loss. Also, it is a health hazard for workers, and there are environmental factors to be considered.

Safety & Quality Control

We must also talk about the safety factors that are associated with these agents. It is often the most underrated benefit that comes with these. How? Simple, because they are colour-coded, it makes it easier to prevent any accidental mixing or labelling.

There is also the added benefit of easily spotting issues like moisture damage, etc., during storage or transport. This visual distinction allows inspectors to quickly identify & address any issues that may arise.

Final Thoughts

There you have it, folks — our take on just how colouring agents improve the properties of fertilisers. Do understand that these are just some of the benefits of using these. When combined with granulation additives & anti-caking compounds, they help ensure that the final product does what is expected from it.
