Nitrate Toxicity during Drought
This summer has proven to be a tough year on agriculture. Sampson County is listed in a severe state of drought and some areas of the County haven’t seen rain since early May. With high heat and little rain pastures and hay fields are suffering. If you’re not careful your livestock too may suffer. Not from heat stress, but from nitrate toxicity.
Under ideal growing conditions plants will absorb the nitrates from the soil and convert them into plant proteins. However, during drought stress, plant growth is decreased and nitrates begin to accumulate, sometimes at toxic levels. Many animals are sensitive to high nitrates. Sheep are typically the most sensitive along with lactating animals. Nitrate levels of 0.0% to .25% are generally considered safe for all types of animals.
To determine if you have high nitrate levels in your pastures or in your hay you can do a forage analysis. For a pasture grab random handfuls of grass through out the pasture. For Hay use a hay probe sample at least 25% of your bales. A forage analysis cost 5.00 and is done by the NCDA Lab in Raleigh. Samples should be sent in immediately. The Extension office can assist in helping you take samples, fill out the paper work, and get the samples sent in. Testing your hay and pastures can save you money and damage in livestock losses during this hot dry weather.
