Asaase Hene: Transforming Cocoa Farming in Ghana with Polysulphate

Asaase Hene: Transforming Cocoa Farming in Ghana with Polysulphate

Cocoa farming is a cornerstone of Ghana's economy, contributing significantly to export earnings. As the world's second-largest cocoa producer, Ghana's agricultural sector continually seeks innovations to enhance yield and sustainability. Enter Asaase Hene, the local brand name for Polysulphate, a multi-nutrient fertiliser by ICL, now making significant strides in Ghana's cocoa industry.

What is Asaase Hene (Polysulphate)?

Polysulphate is a naturally occurring mineral fertiliser extracted from the polyhalite layer over 1,000 metres beneath the North Sea off the UK coast. Deposited 260 million years ago, it is rich in four essential nutrients:

  • Sulphur (SO₃): 48%

  • Potassium (K₂O): 14%

  • Calcium (CaO): 17%

  • Magnesium (MgO): 6%

These nutrients are in sulphate form, ensuring they are readily available for plant uptake. The fertiliser's natural composition allows for a gradual release, aligning with crop nutrient demands over time.

Application and Benefits for Cocoa Farming

Field trials in Ghana have demonstrated Polysulphate's efficacy in cocoa cultivation. Applied at a rate of 375 kg/ha, the fertiliser increased dry cocoa bean yields by an average of 13.6% compared to standard fertilisers and by 70.8% over unfertilised plots. Key benefits include enhanced nutrient supply, improved soil health, and sustainability. Certified for organic agriculture, Polysulphate supports environmentally friendly farming practices.

Collaborative Efforts with COCOBOD

Demeter Ghana Limited, in collaboration with the Ghana Cocoa Board (COCOBOD), is actively promoting Asaase Hene across cocoa-growing regions. Recent training sessions led by agricultural experts from ICL and COCOBOD have equipped farmers with knowledge on sustainable farming practices using Asaase Hene.

Asaase Hene (Polysulphate) is proving to be a game-changer in Ghana's cocoa industry. Its natural composition, coupled with demonstrated yield improvements, positions it as a vital tool for farmers aiming for sustainable and productive cocoa farming. Through strategic collaborations and farmer education, Demeter Ghana Limited and COCOBOD are paving the way for a more prosperous cocoa sector.
