Welcome to HJA Africa’s website. We make OFA ( Organic Farming Aid), which is an organic yield enhancer increasing yields by up to 100%, offering farmers incredibly good value for money. It is also a fungicide and controls soft-bodied pests.

For example,  a peer reviewed research study showed a typical farmer could spend the equivalent of just $5 on OFA to treat a hectare of maize, and increase the value of their yield at harvest by $200!

OFA is effective for all crop types. We get excellent feedback from our wide range of farmer users (see some testimonials on our facebook page), and have strong backing from a range of  independent research studies including peer-reviewed ones.

OFA  can be used on its own or in combination with other inputs.

HJA Africa is based in Ghana (West Africa). We are happy to supply bulk orders anywhere in Africa, working through local importers.

OFA is environmentally friendly, and is safe for farmers and consumers.  It is registered with Ghana’s Ministry of Agriculture PPRSD section (PPRD/PR/19/216-1) and Environmental Protection Agency (PCL/20266/1639G)
