In a stark contrast to 2019, this year’s growing season was drastically drier which meant that participants in the Testing Ag Performance Solutions (TAPS) program had to focus more attention on their irrigation and nitrogen management decisions this year.
Fertilizer-N is a big investment for crop production in Nebraska and elsewhere. After harvest, growers tend to plan their fertilizer-N management for the next year’s crop. But the question is how much nitrogen can they apply to get the most profit from their fertilizer-N investment?
Biomass production, N uptake, and C:N ratio vary widely across the United States. The N in cover crop biomass will be released within a few weeks after termination, however, decomposition varies with soil moisture, soil temperature and C:N ratios.
