Granulation Aids in improving fertiliser performance and plant nutrient uptake 

In the world of agriculture, where every seed hold the promise of a thriving harvest, the science of fertilisation plays a crucial role. Among the most important factors in this sector are granulation aids – essential elements in the fertiliser formulation that significantly to the effectiveness of fertilisers. In this blog, we discuss the role of granulation aids, explore how they revolutionise the way we nurture our crops for optimal growth and yield and also cover their impact on the future of sustainable framing, particularly lignin based granulation aids. 

Demystifying Granulation Aids

Granulation, the process of converting fine powder into granules, is a game-changer in the fertilizer industry. But what exactly are granulation aids, and how do they elevate the efficiency of this process?

Granulation aids also known as binding agents are essential elements in material science. Their function in granulation involves the conversion of fine particles into granules of specific sizes depending on application. Their role in enhancing the efficiency of the granulation process aids in improving flow of the material, achieving uniform sized particles, and adhesiveness of the particles to each other in order to form granules. Different substances can serve as granulation aids, these include; binders, disintegrants, anti-adherents, each having a specific function in optimizing the performance of the final product

There are multiple classes of granulation aids that currently exist, these include: starches, sugars, polymers and lignin-based ones.
From Dust to Diamonds: How Granulation Aids Transform Fertilizer Formulations

The use of granular fertilizer has become ubiquitous due to its controlled nutrient release capabilities, easy storage and handling, reduction in runoff, long-term soil health, opportunity to customize fertilizer, and efficiency in heavy pre-plant applications. Additionally, novel alternatives to conventional fertilizers are becoming more popular as currently used fertilizers often result in progressive soil acidification and reduced crop quality and yield. One solution to soil degradation used to be the use of magnesium-calcium fertilizers, however, this is not efficient enough. As such the use of materials with significant amounts of trace elements such as dolomite, rich in magnesium and calcium, has been shown to improve soil quality, particularly acidified soil. 

Conversely, such materials (which are in powder form), require modification by granulation to improve handling, storage, efficiency and sustainability. Moreover, granulated fertilizers offer a consistent composition, ensuring an even distribution of macro and microelements in the soil. This uniformity helps reduce the likelihood of fertilizer aging, such as the potential for phosphorus to transform into forms inaccessible to plants through volatilization.

Additionally, the use of binders aids in preventing nutrient leaching, thereby promoting environmental sustainability by minimizing the impact on soil and water quality. In essence, the incorporation of granulation aids in fertilizers not only streamlines manufacturing processes but also significantly contributes to the efficacy, environmental responsibility, and overall success of modern agricultural practices.


As we wrap up our exploration of the world of granulation aids in fertilisers, it becomes clear that these unsung heroes are instrumental in shaping the future of agriculture. From enhancing efficiency and sustainability to contributing to bountiful harvests, granulation aids are silent architects of a thriving agriculture landscape. Join us in the ongoing journey to cultivate success and unlock the full potential of our crops through the art and science of granulation aids fertilisers.
