Term
some Main methods of pasture renovation
Definition
-Prescribed burning – prairies in Great Plains
-Fertilize based on soil test recommendations
-Cross fencing
-Interseed legumes
Term
some info about Prescribed burning – prairies in Great Plains
Definition
-Kills undesirable species
-Ash serves as fertilizer
-Breaks seed dormancy
Term
some info about Fertilizing based on soil test recommendations
Definition
-pH hard to adjust
Term
some info about Cross fencing
Definition
-Enable rotational stocking
-Provides plants time to recover and regrow
-Limits over- and under-grazing
-Inexpensive
Term
some info about Interseed legumes
Definition
-Improves quality
-May improve seasonal distribution
-Adds nitrogen
Term
the Most extreme renovation method
Definition
Reseeding
Term
some types of reseeding
Definition
-Tillage
-No-tillage
Term
some details about tillage reseeding
Definition
-Exposes soil to erosion
-Possibility of best seedbed
Term
some details about no-tillage reseeding
Definition
-Requires killing/suppressing existing sod
-Need good seed-soil contact – drill must penetrate thatch layer
Term
things to consider when selecting species in pasture renovation
Definition
-Which species to plant?
-Variety choice is important
Term
things to consider when selecting which species to plant
Definition
-Adapted to region
-Have knowledge of management
-Provide feed quantity and quality needed
Term
things to consider when selecting which variety to plant
Definition
-All varieties (cultivars) are not the same
-Variety selection is important
-Check extension bulletins for comparative data
Term
some details about mixtures of forages
Definition
-Can extend grazing season
-Add variety to diet
-If includes legume, brings free N
-Can adapt to wider variety of environments
Term
some details about forage monocultures
Definition
-Easier to manage
-Lack of variation can limit stability in extreme environments (e.g., under drought, insect, disease pressure)
Term
the question when it comes to the decision of whether to plant a monoculture forage or a mixture of forages
Definition
The question is whether a destabilizing force will upset that monoculture or if having a mixture of species will be better in the long term….
Term
types of forage mixtures
Definition
-Within pasture or hay field
-On the farm level
Term
some details of on the farm level mixtures of forages
Definition
-Maximize productivity of individual monocultures (or perhaps simple grass-legume mixtures)
-Minimize risk of catastrophe by planting several different species in different paddocks
Term
some types of mixtures of livestock in a forage system
Definition
-Mixtures of animals in same paddock
-Mixtures of animals in different paddocks
Term
the grazing used in Mixtures of animals in same paddock
Definition
Complimentary grazing
Term
some details about Complimentary grazing
Definition
-Different species of livestock – beef and sheep
-Eat different species of plants, or graze in different ways
Term
the grazing used in Mixtures of animals in different paddocks
Definition
Creep grazing
Term
some details about Creep grazing
Definition
-Allows calves first entry into new paddocks
-Lets animals with most nutritional needs graze first then follow with others – lactating cows followed by dry cows, for example.
