There has been a lot of interested in testing drought-stressed corn for nitrate levels. Rightly so! Nitrate poisoning is a real concern for livestock production. Under normal growing conditions, nitrate is quickly converted to nitrite, then to ammonia, and finally into plant proteins and other compounds. When plant growth is slowed or stopped, nitrate can accumulate in the plant. Drought, frost, cool, cloudy weather can cause nitrate to accumulate. Rainfall following an extended dry period may cause an immediate increase in nitrates for 2 to 5 days until the plant can concert the nitrate to protein.
