Fertilizer & Cattle

Have you ever had cattle consume fertilizer?  It can happen, and depending on the product, can be a significant problem.  If it contains nitrate (ammonium nitrate or potassium nitrate), it can lead to nitrate poisoning.  Nitrate itself is not poisonous, but it is converted to nitrite in the digestive system.  According to Charlie Stoltenow, North Dakota State University Extension Service veterinarian, nitrite is 10x more toxic than nitrate. 

Nitrite is absorbed into the red blood cells and combines with hemoglobin to form methemoglobin. Methemoglobin cannot transport oxygen as effectively as hemoglobin, so the animal’s heart rate and respiration increase. The blood and tissues of the animal take on a blue to chocolate brown tinge, muscle tremors can develop, staggering occurs and the animal eventually suffocates.

“Fertilizer is good for plants, but not good for cattle,” Stoltenow says. 

I wonder what he thinks about using urea or urea-based feeds as a protein source in finishing cattle?

According to the article, the best way of preventing fertilizer-related nitrate poisoning in cattle is by controlling access to fertilizer. Avoid letting cattle graze immediately after spreading fertilizer and clean up fertilizer spills. Areas where the fertilizer spreader turns or areas where filling (and consequently spilling) take place may have excessive quantities of nitrate available to the cattle. Also, do not allow cattle to have access to areas where fertilizers are stored.

SuperCal 98G & SuperCal SO4 are produced from products that are commonly found in nature (calcium carbonate & calcium sulfate, respectively).  They are not toxic to humans or animals.

Nitrate Toxicity

With corn silage season coming up this is a good time to talk about nitrate poisoning. Typically associated with drought and rain after dry conditions, there are other factors to that can cause high nitrate in forage crops. High rates of N, low or high levels of molybdenum, low sulfur, and low boron, and events that upset normal plant growth like early frosts.

New pastures are known to be high in nitrate, especially the faster they grow, the more toxic they can become. Hybrid ryegrass is one of the most dangerous. If reseeding pastures this fall make sure to add edible clover which normally do not have high nitrate levels.

Nitrate poisoning has been on the rise in the past decade, this could be due to the reluctance of today's generation to lime pastures (molybdenum levels drop with acid soils), increase use of urea on pastures, and less sulfur naturally being applied due to clean air laws.

Nitrate Toxicity is aggravated by:

Excess N application in the autumn after a dry period of no growth
Rain and warmth after a no-grow period
Fast plant growth
Stressed plants, from drought, hot wind, frost, and hail
Low sunshine
Fast eating by underfed, hungry animals
Low pasture molybdenum - below 0.5 ppm, 1.6 ppm is optimum
Molybdenum levels above 4 ppm, especially if pasture sulfur is low
Low sulfur levels, below 0.25 ppm
Low calcium and phosphorus levels
Nitrate is highest in the morning, when rotating cattle wait until mid afternoon

While environment can have an impact on nitrate levels, having the proper soil nutrients in the proper levels is great insurance from nitrate poisoning. As a bonus you'll enjoy better pasture performance, and high gains from your animals.
