National Forage Week: June 16-22

The American Forage and Grassland Council is excited to celebrate the 5th Annual National Forage Week on June 16-22, 2019 as an effort to raise awareness to the importance and impact of forages. As the leader and voice of economically and environmentally sound forage focused agriculture, AFGC understands the impact of forages on the world and wants to share that knowledge by focusing our education efforts during National Forage Week.

Managing Pastures this Summer

Setting a sustainable stocking rate.  Setting the proper stocking rate, defined as animals per acre per year, is a primary determinant in grazing system success.  A stocking rate set too high will result in the degradation of the entire grassland ecosystem.  A stocking rate that is set too low will result in wasted forage and decreased profitability.  In addition, stocking rate also impacts the amount of conserved forage that will be needed.  A stocking rate set too high will result in less grazing and more hay feeding.  Stocking rate depends on many factors such as forage species, soil type, soil fertility level, and grazing management.  In general, supplying each cow-calf unit with 2 to 3 acres of grazable pasture is a good place to start.  In most cases it is better to start with a lighter stocking rate that can be gradually increased as soil fertility increases and grazing management improves.

Grazing management.  Controlled grazing or rotational stocking is a management practice that allows producers to determine how closely pastures are grazed and how long they are rested between grazing events.  Leaving residual leaf area and resting pastures between grazing events allows pastures to re-grow quicker and produce up to a third more forage in a given grazing season (Sollenberger, et al., 2012).  Some forage species are better adapted to close and frequent grazing than other.

Soil fertility.  The soil fertility can have a profound impact on both the productivity and botanical composition of pastures.  When fertility is low, improved forage species like tall fescue and orchardgrass and red and white clover become less productive and weed species that are better adapted to lower fertility fill in the gaps. Fertilizer and lime applications should ALWAYS be based on a recent soil test.  If funds are limited, apply lime if needed.  Lime not only reduces soil acidity, but also makes nutrients in the soil more available to plants.

Hay and silage remove large quantities of nutrients.  In contrast to grazing, making hay or silage removes large quantities of nutrients.  These nutrients must be replaced to maintain soil fertility, and stand health and productivity.  Each ton of hay that is removed from a field takes with it approximately 15 lb of phosphate and 50 lb potash.  In a good year a tall fescue-clover mix may yield 4 tons per acre and remove 60 lb phosphate and 200 lb of potash.

Successful pasture management requires an integrated approach that involves the soil, plant, and animal.  This means we need to select well adapted forage species and manage them in a manner that creates a healthy and vigorous sod that excludes weeds from our pastures.  When we combine this with clipping and the judicial use of herbicides, we will have a winning combination! ~ Dr. Chris Teutsch.

Broom sedge is often an indication of low soil fertility. In this photo Greg Brann discusses approached to reclaiming broom sedge infested pastures. 

 

Forage Timely Tips: June

  • Continue hay harvests. Minimize storage losses by storing hay under cover.
  • Clip pastures for weeds and seedheads as needed.
  • Slow rotation allowing for a longer recovery period.
  • Use portable fencing to decrease paddock size and increase paddock number.
  • Do NOT grazing below the minimum desired residual height.
  • Crabgrass, a warm-season annual grass, can provide high quality summer grazing. Remember crabgrass needs some annual soil disturbance to keep coming back.

 

Quote of the Month: Leaving new bales in the field is like leaving dirty dishes in the sink. Sure, it’s convenient at the time, but in both situations, after a while they begin to stink ~ Lauren Peterson

Hay will never be in a better nutritional state than the moment it is cut. It simply quotes bookdeteriorates from that point. The only thing you can then control is getting the hay baled, out of the field and into good storage conditions as rapidly as possible. However, it is important to be certain that hay reaches a safe moisture level and internal temperature before moving it to storage to avoid spontaneous combustion. Otherwise, fire can occur in hay stored outside or in a barn. Forage-Livestock Quotes and Concepts, vol. 2 is available here.

 

UK Weed Science to Host a Pair of Field Days at UKREC in Princeton

The University of Kentucky Weed Science Program will be hosting two field days at the UK Research and Education Center (UKREC) in Princeton, Kentucky in 2019.  The Pest Management Field Day will be held on July 2, 2019 and the Spray Clinic will be held on July 18, 2019.

Pest Management Field Day

The Pest Management Field Day will be a half day event starting at 8:30 am with sign-in beginning at 8:00 AM.  The field day will include field talks and plot tours covering weed science research and corn disease research.  The event will culminate with lunch and optional informal self-guided viewing of weed science and corn disease research plots.

Those wishing to participate in  the Pest Management Field day can pre-register online or by calling (270)-365-7541 ext. 0.  There is no cost to attend the Pest Management Field Day. The Pest Management Field Day has been approved for CCA CEU credits and PAT credits have been requested. Find more info here.

KATS Spray Clinic

The Spray Clinic will also be held at the UKREC in Princeton as part of the Kentucky Agriculture Training School (KATS).  The event will occur on July 18 from 8:30 AM to 4:00 PM with sign-in beginning at 8:00 AM.  The clinic will include spray technology overviews, spray equipment maintenance, herbicide application considerations, fungicide application considerations, and drift management.  Speakers at the event will include Dr. Tim Stombaugh, Dr. Kiersten Wise, and Dr. Travis Legleiter of the University of Kentucky.

Online pre-registration is required for this event.  The cost to attend the Spray Clinic is $105 and includes lunch and refreshments. The Spray Clinic has been approved for CCA CEU credits and PAT credits have been requested. Any questions about either field day can be directed to Dr. Travis Legleiter (Travis.Legleiter@uky.edu). ~ Kentucky Pest News
