Hot, dry weather is impacting part of the state which in turn is impacting the water quality for grazing cattle.  In some pastures, the only water source available are ponds and dugouts which can contain hidden dangers to the cattle.

Blue-green algae also known as cyanobacteria blooms are caused by excess levels of nitrogen and phosphorus.  These nutrients are commonly introduced from runoff or soil erosion from fertilizer and manure.

As we progress into summer, forage quality can rapidly change depending on factors like rainfall, temperature, etc.  A good example of the dynamic interaction of rainfall and forage quality is shown in Table 1. In the Sandhills, 2002 and 2018 were drastically different in total precipitation; however, forage quality driven by forage growth and maturity in terms of crude protein were very similar in a drought or wet rainfall year.  Understanding these relationships is important in making proactive management decisions.

Annual forages are a useful tool to help manage risk. From a crop management standpoint, they can be used to manage erosion risk and build more resilient soil profiles. From a livestock management standpoint, annual forages can provide a valuable source of additional feed resources. They can serve an important role in a cattle producer’s drought management plan and overall strategy for controlling feed costs.

Precipitation and temperature play major roles in pasture productivity, and knowing how to adjust grazing to match current conditions is key.  Are you shifting your management to meet recent weather?
