Potato production in Canada typically involves uniform application of agrochemicals (fertilizer, lime andpesticides) during a growing season, ignoring spatial and temporal variations that exist within fields. Uniformapplication not only increases the production cost but also adversely affects our environment (increasedgreenhouse gas (GHG) emissions, nitrate leaching into sub-surface/ground waters, nutrient runoff into waterbodies, damaging aquaculture and fisheries and deterioration of air quality).This project will address the urgent needs of the Potato Board Prince Edward Island (PEI) to find a novel andinnovative solution to direct nutrient management strategies on an as-needed basis. This project will evaluatethe feasibility and practicality of the electromagnetic induction based sensor (DualEM) to develop managementzones (MZs) for site-specific application of crop inputs (Fertilizer and lime). The main goal of this research isto: 1) calibrate the DualEM sensor in variable soil conditions across the PEI using physical soil sampling andanalysis, 2) identify the optimal frequencies of the DualEM sensor to sense/predict soil fertility status forsite-specific nutrient management, and 3) delineate non-destructive sensor based MZs to optimize crop inputson an as-needed basis. Nutrient management on an as-needed basis has a strong potential to increasefertilizer/lime use efficiency, reduce production cost, and mitigate environmental risks.Currently, there are no protocols available for Potato Board PEI to implement site-specific nutrientmanagement. This project will provide Potato Board PEI with an innovative and non-destructive method todevelop map-based MZs using a DualEM sensor. The developed MZs can optimize nutrient managementprecisely. Furthermore, this research will provide a new knowledge stream based on acquisition of necessarydata to support/implement site-specific nutrient management to improve economic and environmental benefits.

加拿大的马铃薯生产通常涉及在生长季节均匀地应用农业化学物质（肥料，石灰和肉药），忽略了田野内存在的空间和时间变化。 Uniformapplication not only increases the production cost but also adversely affects our environment (increasedgreenhouse gas (GHG) emissions, nitrate leaching into sub-surface/ground waters, nutrient runoff into waterbodies, damaging aquaculture and fisheries and deterioration of air quality).This project will address the urgent needs of the Potato Board Prince Edward Island (PEI) to find a novel andinnovative solution to direct营养管理策略基于需要。该项目将评估基于电磁诱导传感器（Dualem）开发管理区（MZ）（MZS）的可行性和实用性，以针对作物投入（肥料和石灰）的特定地点应用。这项研究的主要目的是：1）使用物理土壤采样和安纳尔分析在整个PEI的可变土壤条件下校准双极传感器，2）确定双重传感器的最佳频率，以感知/预测土壤生育状态的表面育肥状态，并确定3）DILINEATE DILINEATE非损失传感器的基于基于MZS的基础，以使基于基于的MZS构成nitucted speptsss neptssssss notectectssss notectectsss notecte notectect。在需要的基础上，营养管理具有强大的潜力，可以提高效率/柠檬的利用效率，降低生产成本并减轻环境风险。目前，PEI尚无协议，可用于实施特定地点的营养管理。该项目将使用Dualem传感器为PEI提供创新的和非破坏性方法的基于地图的MZ。开发的MZ可以优化营养管理。此外，这项研究将基于收购必要数据以支持/实施特定地点营养管理以提高经济和环境益处的新知识流。
