Cultivation of Spirulina (Limnospira platensis) using NPK fertilizer as a low-cost media and its implications for the semiarid regions of Southern Africa
Amare Gessesse
IntroductionIn the semi-arid regions of Southern Africa, livestock farming is a key source of livelihood, but its productivity is constrained by the availability of nutritionally adequate feed, a challenge exacerbated by climate change. The microalga Limnospira platensis (commonly known as Spirulina) presents a climate-smart alternative for producing good quality animal feed. However, its widespread use is limited by high production costs, particularly those associated with labour and cultivatio
