Response of irish potato (Solanum tuberosum L.) to the application of potassium fertilizer in acidic soil: A review

In Ethiopia, it has long been assumed that Ethiopian soils are high in K and that there is no need for its application, based on a 40-year-old research conclusion. However, due to continual mining, leaching loss, soil erosion, and other factors, shortage in K is likely to develop in some soils over time. Soil acidity is a severe concern for crop production in the highland’s areas of southern Ethiopia, and it is usually linked to K shortage. Many experts have stated that the results of soil chemical analysis data of samples revealed that the available K content for plant growth and development is fairly low. According to various researchers, the application of K enhanced potato tuber yields significantly when compared to the control in acidic highland soil.
