This year has been a weather rollercoaster with multiple spells of drought and flooded conditions. These adverse growing conditions can cause unforeseen challenges with the forages you have stored away. We have had multiple reports of high nitrate levels this year. The first reports of high nitrate levels were in June harvested oats after the early season drought. Recently we have had additional reports of dangerously high nitrate levels in millet hay with the recently dry weather. Producers have also told us that they are struggling with excessive silo gas coming from corn silage.
Plants readily take up nitrates from the soil, even under cooler conditions. Once in the plant, nitrate is converted to nitrite, then ammonia, and finally into amino acids and plant protein. Any environmental stress that significantly slows down plant photosynthesis and metabolism can lead to excessive nitrate levels in the plant because the nitrate uptake from the soil will be faster than its metabolism into plant protein. Such stresses include Continue reading Keep Forage Nitrate Toxicity in Mind This Year
