Nitrate toxicity in drought-stressed corn

Drought-stressed crops such as corn and sorghum tend to accumulate high levels of nitrate in the lower leaves and stalk of the plant. It is wise for producers to test their drought-stricken forage prior to harvest.

Test to prevent nitrate and prussic acid poisoning

Many Kansas cattle operations rely on some type of harvested feed to use in the winter months. Forages in the sorghum family are prone to two different problems for feeding cattle, nitrate poisoning and prussic acid poisoning. Learn about how to test for these and key characteristics of each toxin.

Testing methods for nitrates in forages

In last week's eUpdate, nitrate and prussic acid poisoning was discussed when feeding cattle certain types of forages. In this follow-up article, we share information on the different tests available and how to collect a representative sample.

Nitrate toxicity in drought-stressed corn and sorghum

Drought-stressed crops such as corn and sorghum tend to accumulate high nitrate levels in the lower leaves and stalk of the plant. Nitrates accumulate when stresses reduce crop yields. Farmers should test their drought-stricken forage prior to harvest. High levels of nitrate can be toxic when fed to livestock.

Test to prevent nitrate and prussic acid poisoning

Many Kansas cattle operations rely on some type of harvested feed to use in the winter months and common among those sources is forage sorghum, millets, sorghum-sudangrass, and sudan. When feeding cattles, forages in the sorghum family are prone nitrate poisoning and prussic acid poisoning. Learn the difference and how to test for these before a problem occurs.

Testing methods for nitrates in forages

When making harvesting or feeding decisions for forages that have potentially accumulated nitrates, our tendency is to want immediate answers. Laboratory analysis is by far the best test of nitrate toxicity. Two types of quick tests exist, and it is important to understand the limitations of these tests when considering their use.
