Potassium Fertilizer Research is Reviving Potato Production in China

China is the largest global potato producer and Inner Mongolia (IMAR) is one of the country’s major potato-growing regions. Without proper K fertilization, a reduction in potato yield, quality, and farmer profitability has been observed. The IPNI China Program established a research project that helped the region’s potato farmers increase their productivity and profitability by identifying the most beneficial rates, sources, and times of K application.
