“Precision nitrogen management for improving yield and protein content in wheat” with Dr. Olga Walsh.

Nitrogen is one of the most important nutrients for crops, which is required in large amounts for crop production and demands precise nutrient management methods due to its highly mobile property in plants and soils and high chances of leaching. Precise nutrient management is also important for improving the yield and quality of grains, minimizing the input, and maximizing the efficiency. Assessing the real-time plant growth, biomass production, and nutrient depletion in the soil using different precision agriculture techniques like drones, remote sensing, unmanned aerial vehicles (UAVs), and other camera-based devices helps optimize nutrient management. In this episode, Dr. Olga Walsh shares her research on precision nitrogen management for yield and protein content estimation on spring wheat and sugar beet by using different hand-held sensors, drones, and remote sensing approaches.

Tune in to learn more about

·         What values are best to look for when doing remote sensing in wheat

·         How drones, remote sensing, and camera applications are helping predict biomass and nutrient requirements

·         What yield and protein content was estimated from the sensors tested

·         How hand-held and UAV sensors compare
