Manejo de Pastos: ¿Que tanta humedad hay?

Amigos Ganaderos,

Hay zonas en las que han llovido mas de 25 pulgadas y el pronostico nos indica que lloverá aun mas.

Les compartimos este texto que nos da puntos de vista de como manejar nuestros pastos.

Esperamos que les aporte buenas ideas.



How wet is you pasture?


Spring of 2011 had brought significant challenges to livestock grazing
operations. In many areas, 10 to 12 inches of rain fell from April to May,
preventing land from drying out during early spring grazing. Many times when
the spring grazing season begins, pastures are soft and wet and this year
had been exceptionally wet in many areas. Normal grazing can quickly get
these pastures muddy from damage by hoof traffic where livestock hooves are
punching through the upper sod layer.

Special grazing techniques are needed to limit damage in soft, muddy
paddocks. One way is to graze all your cattle together in one small
"sacrifice" paddock until the ground gets solid again. This technique may
destroy the area grazed and require reseeding in that individual paddock.

This works for 3 to 4 days. If more time is needed, you will need to pull
cattle to a sacrifice lot and feed hay until the ground is firm enough to
turn back out. This may create some forage maturity challenges that require
mechanical harvest. Both options can help protect most of your pasture acres
from trampling losses and should be considered when conditions are not
improving.

The worst thing you can do is graze a pasture for several days until it's
all torn up and then move to a new area. Repeated trampling over several
days greatly weakens plants and can reduce production for months, or even
years, due to subsoil compaction. In contrast, pastures muddied up by
grazing only briefly usually recover quickly. It may not happen as fast as
when the ground is solid, but it will be fast enough to minimize yield or
stand loss.

Take advantage of this rapid recovery by moving animals frequently, at least
once a day, to a new area.
