Potato's Role in Sustainable Agriculture and Agroecology

As one of the most important non-cereal food crops in the world, potato plays a key role in sustainable agriculture and agricultural ecosystems. The literature review shows that potato can not only efficiently utilize limited resources and improve food security, but also promote ecosystem health and improve farmers' livelihoods through diversified planting and innovative management methods. The use of sustainable measures such as organic fertilizers, cover crops, ecological planting and biostimulants has significantly improved yield, quality and soil health, and reduced dependence on chemical inputs. Through the application of organic fertilizers in Shandong Province, China, potato has not only improved production efficiency and economic benefits, but also optimized the input structure and promoted the green transformation of regional agriculture. Innovative technologies such as hydroponics provide new paths to address climate change and land degradation. Potatoes have shown unique advantages in achieving nutritional security, ecological protection and sustainable rural development.
