Fall applications of manure have the potential for high nitrogen (N) losses. Cereal/grass cover crops have been shown to take up fall applied N. Similary, using nitrapyrin (Instinct) has been shown to prevent loss of fall applied N. No studies have been conducted to evaluate combining these tools to prevent N loss. This experiment was performed in 2016 and 2017 on a well-drained and somewhat poorly drained silt loam soils. This study was conducted to determine if using Instinct and spring wheat (Triticum aestivum) with fall applied manure could improve nitrogen availability to corn (Zea mays) due to a synergistic effect.
