Africa is considered a global hub for the production of cocoa and coffee. Millions of smallholder farmers and consumers worldwide view these two crops as integral parts of their lives. In the African continent, some countries, such as Ivory Coast, Ghana, and Nigeria, are leading producers of coffee, whereas Ethiopia and Uganda also grow coffee to a substantial amount. Given their share of nearly 70% of the global coffee market, African farmers strive to improve their crop production. But the dilemma is that they must face various challenges of low yield, pest and disease attacks, poor soil fertility, and other challenges that lead to low productivity and bad quality of crops.
There are many ways to handle these challenges, but one of the best is Sulphur WDG (Water Dispersible Granules). This is a Sulphur-based fertilizers that can effectively improve nutrient uptake and crop health. With the help of this article, we will try to explore how Sulphur WDG can improve the farming of cocoa and coffee for enhanced productivity and sustainability.
The Importance of Sulphur in Plant Growth
Sulphur, an essential nutrient, helps plant growth and aids in the formation of proteins, enzymes, and vitamins. For cocoa and coffee farming, Sulphur aids in:
Protection of disease: Sulphur helps plants protect themselves from fungal infections, which are common in humid environments.
Nutrient consumption: Sulphur helps coffee and cocoa plants grow by enhancing uptake of nitrogen and phosphorous.
Increase in production: When crops are cultivated with an adequate mix of Sulphur, the plants become more productive and produce beans of higher quality. African soils and cocoa production areas are deficient in this nutrient, although Sulphur is so useful in growing them. Farmers have been farming intensively for years with these depleted Sulphur levels, and they don’t realise the inclusion of Sulphur.
What is Sulphur WDG?
Sulphur WDG is a potent Sulphur-based fertilizer that is in the form of water-dispersible granules. When combined with water or applied as foliar spray during irrigation, these granules tend to break down easily. It is this water-dispersible nature of granules that are evenly distributed over the crops.
When compared to traditional Sulphur fertilizers, Sulphur WDG offers a distinct advantage.
Simple application: Small-scale farmers can effortlessly apply this WDG solution using a conventional irrigation system.
Gradual release of nutrients: Granules typically release slowly. This is how plants get Sulphur WDG in a steady way throughout the growing season.
Safe for the environment: When farmers use Sulphur WDG, they should keep in mind that they are not doing harm to the environment, as this fertilizer reduces the risk of leaching and any type of contamination.
Cost, efficiency, and sustainability: The biggest advantage with Sulphur WDG is that it is not expensive in comparison to chemical-based Sulphur fertilizers. Sulphur WDG is simple to apply, so one can get long-lasting results with fewer applications. One can be guilt-free as this fertilizer is environment-friendly. Moreover, its slow release mechanism minimises runoff and reduces contamination.
Coffee Yield Improvement with Sulphur WDG
Sulphur is useful in maintaining yields and ensuring high-quality beans. About 15 to 20 kg of Sulphur is required for every metric ton of clean Arabica coffee. On the other hand, a variant Robusta needs about 20–25 kg. This nutrient is vital for the growth and development of coffee plants, especially for the size and flavour of coffee beans.
1. Yield Improvements
Coffee farmers face a challenge of low coffee yield as the soil is not nutrient rich. By applying Sulphur to soils, they can enhance the production of coffee and subsequently reach their full potential. On an estimate, production quantity was found to be between 1 and 1.5 tons per hectare under optimal conditions with proper application of Sulphur WDG.
2. Quality increases
Sulphur is also used in increasing the flavour of coffee beans. This increased quality of coffee decides the price of coffee in international markets. Thus, inclusion of sulfur WDG is also vital in the speciality coffee industry, where quality has a major significance.
Cocoa Yield Improvement with Sulphur WDG
Cocoa farming is done at its best with sulfur. African cocoa farmers face the same old problem of low yield when they don’t pay attention to poor soil health and nutrient deficiency. The crop potential is much more than 150 kg per hectare that they are growing currently. On the other hand, when farmers are using sulfur in their soils, the yield rises dramatically. There is research that suggests that farmers are able to grow about 800 kg per hectare when they apply Sulphur and other nutrients in a justified manner.
1. Nutrient management and yield increases
The use of Sulphur WDG not only boosts cocoa yield but also results in healthy, larger cocoa pods. For example, when proper soil fertility management was done, pod weights increased to an average of 486.2 grams per pod. On the other hand, the number of pods per tree has risen to around 56.87. Seeing all this, one can say that farmers are able to increase their turnover and start earning more.
2. Disease control and improved soil Health
Boosting yield is one benefit. There are many more. Sulphur WDG use saves the crops from the hazards of black pod disease too. In coffee, the disease that affects coffee rust. These diseases can damage the crops if they are not checked. So, to tackle them, farmers use chemical fungicides, which are often expensive for smallholder farmers. At the same time, if farmers use natural sulfur WDG fungicide, they can get relief from costly treatments.
Soil health can also be restored by sulfur in a few other ways, as it increases the soil's ability to retain other nutrients such as nitrogen and phosphorous. Certain regions in Africa, including Ghana, Ivory Coast, and Cameroon, experience soil depletion. Here, we can use Sulphur to help restore soil structure, thereby making the land more productive and nutrient rich in the long run.
Practical Considerations for African Farmers
To get and see the benefits of Sulphur, WDG farmers are advised to apply it correctly and during the right season. Here are some tips:
Timing: Sulphur WDG is advised to apply at the start of the growing season or during critical growth phase so that Sulphur is available to the plant when it is needed most.
Application rates: Apply 15–25 kg of Sulphur per ton of clean Arabica or Robusta beans for coffee. Apply Sulphur regularly for healthy pod development and overall yield in case of cocoa.
Conclusion
Cocoa and coffee farmers in Africa are becoming more prosperous by including Sulphur WDG in their practice. With this, they can improve crop yields, maintain better flavour, and use environmentally friendly farming methods. As there is Sulphur deficiency in the soil of Africa, by including Sulphur WDG, they can get a 15 to 25% yield increase, reduce the chances of disease, and enhance the quality of their beans. As the demand for high-quality coffee and cocoa is increasing, farmers in Africa are following effective and innovative farming solutions.
