Many of us are looking forward to warmer weather and longer
days. If you manage a pasture for
horses, or are planning to plant one, now is the time to make those final management
decisions and plans. What you do now
will ensure spring pasture growth starts off right and leads into a productive
summer.
For those wanting to plant a new pasture or hay field, your
first decision will be what to grow. For
those who live in the Coastal Plain part of NC, bermudagrass or another warm season
grass may be what you choose to grow and/or manage. Are you interested in growing hybrid
bermudagrass, or maybe a seeded variety?
There is a difference, starting with when and how to get this done. Hybrids spread and reproduce by stolons
(above ground growth) and rhizomes (below ground growth). Any seeds seen on a hybrid plant are sterile,
so we must start a field by planting “sprigs” which are small plants that have
been dug from an established field and then re-planted to a new field. Hybrid bermudagrass, such as Coastal, Tifton
44, or Midland 99 should ideally be planted anywhere from mid- February to mid-March. There are sprig suppliers in the area that
sell and will deliver sprigs to your field.
Extension can assist with contacts to sprig suppliers if this is your
choice. Seeded varieties of bermudgrass
are also available and may be a better choice for small acreage locations or
the flexibility of later planting dates.
Of course, there are other forage choices you might decide
to plant. Bermudagrass is a perennial
plant, which will grow throughout the spring and summer and become dormant
during the winter months but come back again the next year, and that is one
reason it is often preferred. However,
there are annual grasses that could be planted, such as pearl millet or crabgrass,
and these will grow well and provide plenty of grazing throughout the warmer
months too. If you want the flexibility
of planting something new each season, an annual such as these may be a better
choice for you.
Either way, if a soil sample has not been taken in the past
2-3 years, it’s time to take one. Ideally, a soil sample is taken prior to the
growing season, but anytime is better than none. Soil fertility changes over
time and may not always be optimum for forage growth. Both establishing and
planting forages for new pastures and maintaining fertility on existing
pastures require soil sampling.
Pastures in southeastern NC will need to maintain around a 6-6.5 pH for
maximum productivity. Soil pH tends to
drop off over time and additional lime may need to be applied in order to bring
these levels back to normal. The soil sample will provide useful information
with both lime recommendations and fertilization needs. Stop by the Extension office
to pick up a soil test box and instructions on sampling.
Another important step to starting off spring growth is
fertilization. Meeting the needs of the
plant will allow for the optimum production of the crop, whether for grazing or
hay. Fertilization for warm season
grasses should be applied in split applications throughout the growing season,
generally with the first application in April or early May. Again, the soil test is a handy tool in
knowing what the nutrient needs of your pasture are, being based on what is
currently available in the soil and depending on the type of pasture you are
growing.
Along with the spring growth of our pastures, comes the
growth of various weeds. There are
several products on the market to help with this. Emerging warm season weeds, such as pigweed,
dogfennel, bitter sneezeweed, sicklepod, and horsenettle can be effectively
controlled as long as they are treated while still immature. At the same time, chemical herbicides
generally work best when applied in moderate temperatures (60 degrees or better).
A precaution to note: some herbicides are damaging to neighboring crops, such
as tobacco and cotton, so be careful to select a safe product if these crops
have been planted close by. Choosing to
apply herbicides during calmer days or times of the day is also a good idea as
wind will carry these chemicals farther than you might think.
In addition to controlling broadleaf weeds that invade our
pastures and hay fields, there now are more options for grass-type weeds. Many fields battle competition from crabgrass,
bahiagrass, goosegrass, and vaseygrass just to name a few. Once you’ve identified the weed or weeds you
are dealing with, a selection can be made of the most ideal, appropriate, yet
economical method or chemical to achieve this goal. Your county agricultural extension agent will
be glad to assist you in decisions to get your spring pastures started off
right.
