Wetlands provide ecological and economic benefits

Wetlands come in many different forms. They can be tidal zones, marshes, bogs or swamps among many other types. However, they all share characteristics that make them wetlands. They are areas where water is present above or near the surface of the soil for at least a portion of the year, and the soil and vegetation present is determined by the presence of water. Some wetlands need to be dry for part of the year to maintain their hydrologic cycle. Wetlands provide several ecosystem services such as reducing erosion, recharging aquifers and providing habitat for several wildlife species.

Grazing affects plant root growth

Over the years I have seen many grazing operations in many parts of the country. I have seen places that never seem to grow as much grass as they should, and I have seen places that always seem to have lots of grass. Likewise, I have seen places that have been hurt by the extreme weather of the past several years, and I have seen places that have tolerated the extreme weather quite well. The places that have lots of grass and are doing well don’t necessarily have better soil or get more precipitation, and they may not be stocked lighter or rested more days per year. So what is the difference? Roots and the effects that management has on the roots.

Cattle nutrition rules of thumb allow quick estimation

Rules of thumb can be dangerous because they are simplified, generalized algorithms that we use instead of a more detailed, accurate calculation. Many times, however, rules of thumb are very useful when you need a quick estimate of a quantity or relationship. Rules of thumb in the cattle business can be developed from cumulative years of experience from many producers and are often verified when they are evaluated with replicated research studies.

Key steps facilitate formation of associations

With the increased publicity regarding controlled burning and wildlife management associations, some people have expressed interest in forming an association but do not quite know where or how to begin. There are many ways to form an association, but there are some important steps to consider.
