I am writing with my good wishes for 2024, and to share some highlights of progress made  during 2023 by HJA Africa’s OFA liquid fertilizer for all crops.

First,  thank you for your interest, support or  partnership with us at HJA Africa. So many people have helped us  make this a year of significant progress for OFA, and we appreciate you all.

Our mission is  to catalyse  doubling net  farm incomes across Ghana and then Africa sustainably, and so transform the continent’s development.


In 2023 we have made some early strides towards this, by adding up to $10m to farm profits in Ghana, and by building  foundations for   greatly increasing  that figure in the  coming year in Ghana and its neighbours.

We have increased our sales close to 3 times compared to 2022, helped by a  significant advertising  campaign including recruiting Anim Addo, who is Ghana’s best known agriculture journalist, to become  OFA brand ambassador.

We have  demonstrated some significant Unique Selling Points for OFA for the key crops of rice and mango.

For rice, field trials showed OFA to be more effective against rice blast disease than synthetic fungicides costing more than twice as much,  on top of OFA accelerating time to harvest by ten days and giving substantial yield increases.

For mango,  OFA is proving effective in many farmer trials against the most serious problem for most mango farmers in Ghana, BBS (Bacterial Black Spot) as well as assisting flowering, reducing flower drop, dealing with mealybugs, helping solve anthracnose,  and generally substantially increasing yields, all at low cost.

For cocoa, we are getting excellent feedback from the  growing numbers of farmers using OFA across Ghana.

OFA won awards as Outstanding Ghana-made fertilizer in the 2023 Ghana Agricultural and Agro-Processing Awards, and  African organic fertilizer of the year at the 2023 African Agricultural Excellence and Leadership awards. We are grateful for this recognition of our growing impact and success.

We continued  partnerships with several research institutions including CSIR SARI who published important journal  papers  confirming OFA’s outstanding  cost effectiveness for maize and for cowpea, based on three years of field work results. We are  also starting new research trials of OFA with the West African Centre for Crop Improvement, to demonstrate  how OFA can cut production costs whilst increasing yields  for vegetables.

We  completed registration of OFA for use  in Togo and made progress on  registration in Burkina Faso. We also registered with Ecowas for import tariff  free exports of OFA within West Africa, ready to expand OFA  sales into Ghana’s neighbours in 2024.

We made significant improvements to  our production facilities, and now have capacity to produce 1.5 million litres a year of OFA, sufficient to treat up to 3 million acres of crops for the  growing season, and more than enough to meet Ghana’s fertilizer requirements.

We strengthened some of our internal systems and are continuing  work on others, including a new Monitoring Evaluation and Learning system, to ensure we are well prepared for further growth in both impact and sales in 2024

We are very grateful to GIZ for awarding us a grant in 2023 which has significantly assisted our progress.

Once again, our thanks to all of you who have helped us in ‘23, and we  look forward to achieving much more in ‘24!

Wishing you a very happy and healthy new year
