This module will cover important concepts of nitrogen management in agronomic systems for profitable and environmentally safe crop production.
This module is part two in a series of 10 that present information to help the viewer understand the principles of nitrogen management. The materials address site specific nutrient management decisions and practices through the context of 4R Nutrient Stewardship (the right nutrient source applied at the right time, the right rate and in the right place). Information is presented on basic nitrogen processes in the soil-plant system; rate determination and economic response; soil testing and rate adjustment; application timing, product and placement; chlorophyll/canopy sensing and plant sampling; variable rate technology; and, case studies in nitrogen management.
These materials were created with funds provided by USDA NRCS and The Fertilizer Institute (TFI). The educational modules were created by Iowa State University in cooperation with The Fertilizer Institute (TFI), the International Plant Nutrition Institute (IPNI) and USDA NRCS.
