Which outcome accelerates if legume root nodules decompose?

💡 Explanation

Nodule decomposition releases fixed nitrogen as ammonium (NH4+), which soil bacteria quickly convert to nitrate (NO3-) via nitrification. This increases soil nitrate concentration locally because nitrification accelerates rather than causing decreased fixation or a symbiotic breakdown, therefore accelerating nitrate abundance.
