Precise management of agricultural inputs (fertilizer, pesticides, irrigation, etc.) is one of the most significant challenges that the agricultural production system is facing. Currently, crop management practices within potato fields are implemented uniformly with inadequate attention being given to substantial variations in soil, crop, potential yield, climate and topographic features. Uniform applications not only increase the cost of production but also pose a serious threat to the environment (increased nutrient runoff to water bodies, sub-surface/groundwater leaching, volatilization and greenhouse gas emissions). This situation emphasizes the need for increased crop production, profitability and environmental protection, but this cannot be achieved if the fields are managed uniformly.

精确管理农业投入（化肥、杀虫剂、灌溉等）是农业生产系统面临的最重大挑战之一。目前，马铃薯田内的作物管理做法是统一实施的，没有充分注意土壤、作物、潜在产量、气候和地形特征的重大变化。统一施用不仅增加了生产成本，而且对环境构成严重威胁（流入水体的养分增加、地表下/地下水沥滤、挥发和温室气体排放）。这种情况突出表明需要增加作物产量、利润和环境保护，但如果对田地进行统一管理，就无法实现这一点。
