South Africa's post-apartheid Black farmers commonly referred to nowadays as "emerging farmers" need knowledge support to be successful in agricultural productions. Web-based learning enables knowledge users and knowledge providers to actively engage interactively and provides a dynamic platform of knowledge support with unparallel flexibility and convenience. However, this technology is yet to be adequately harnessed to the benefit of South Africa Black emerging farmers, who urgently requires knowledge support that could enable their transformation into market-oriented farming. In this study we present a model to solve this problem. The research revealed that weakly on-demand knowledge support, lack of requisite formal agricultural education, management skill and knowledge for market-oriented farming will remain a major setback to the transformation of Black emerging farmers. The researcher proposed an agricultural knowledge support portal-model. Knowledge support portal holds apromise to enhance agricultural knowledge acquisition and utilization, for the transformation into market oriented or commercial farming.
