Soil nutrient mapping has been implemented in agriculture for the last 40 years. Ongoing economic pressures in agriculture to increase crop yields while sustaining farmer profitability demands in-depth knowledge of soil nutrients. Spatial and temporal variability of yield-limiting factors have been recognized for a long time, and, with such information, farmers have technologies to manage their fields site-specific. However, farmers still tend to manage their fields uniformly because it takes cost, labor, and money to assess and monitor soil health conditions by traditional lab-based methods. We have used a rapidly emerging hyperspectral sensing technology to assess plant-available nutrient content in soil, especially nitrogen, for the use of optimizing in-season nitrogen management.
