Stocktake software

The Stocktake computer software has been replaced by the Stocktake Plus app, released April 2013. If you don't have a smart phone or tablet you may install and use the Stocktake software. However, please note this software will not be supported with updates, unlike the Stocktake Plus app. For best results and improved functionality we recommend you upgrade to the Stocktake Plus app when you have a suitable device.

Grazing land condition

The capacity of grazing land to respond

to rain and produce useful forage… …a measure of how well the grazing ecosystem is functioning.

slide-14
SLIDE 14

Linking it together!

Land Condition

  • Pasture condition
  • Soil condition
  • Woodland condition

Long-term paddock management Slow Overall health of the land, ecosystem function, biodiversity and long-term carrying capacity

Pasture Condition

  • Presence of 3P grasses
  • Crown cover and health
  • f 3P grasses
  • Species diversity
  • Weed infestation

Long-term paddock management Slow Part of land condition, potential growth response

  • f pasture after rain, long-

term carrying capacity

Type of change Influences: Rate of change: Significance: Forage Condition

  • Pasture quantity
  • Pasture quality (proportion
  • f green, stage of maturity)

Weather, seasonal conditions, paddock management, pasture condition Quick (seasons) Forage budgeting for stock, animal performance (LWG) and short-term carrying capacity

Adult Equivalent (AE)

A standard way of referring to different classes of animals and the amount they eat is by comparing their intake needs relative to a 450kg steer. 450kg steer = 1 AE 450kg lactating cow = 1.3 AE 250kg weaner = 0.6 AE 50kg lactating ewe = 0.14AE 50kg dry ewe = 0.1AE

*The Stocktake software has calculators for converting number to AE

Feed Utilisation

Safe utilisation rate is the maximum rate of average annual use consistent with maintaining or encouraging good land condition.

Forage Budgeting Concepts

slide-22
SLIDE 22

22

Forage budgeting

It can also importantly help you plan to meet the ground cover targets at the end of the dry season while maintaining or improving land condition. Demand Supply Regular forage budgeting is a tool that managers can use to refine stock numbers based on seasonal forage availability (short-term carrying capacity)

slide-23
SLIDE 23

Forage condition

Quantity and quality of feed available (supply) to grazing stock at any point in time.

slide-24
SLIDE 24

24

How much pasture for grazing?

Total pasture yield

Residual (Kg DM /ha) How much you want left in the paddock at the end of the budgeting period

Available for grazing (Kg DM/Ha) Detachment (%) That which will be trampled, leaf drop, insect consumption etc…

  • Avg. 15%

Unpalatable feed (%) Unpalatable species and dead material

How would you tackle this paddock?

How do we cope with all this?

slide-27
SLIDE 27

Accessible Yield:

Use a weighted average across samples:

Animal Science

For example…

High yield 15% area 3200 kg/ha Moderate yield 35% area 2000 kg/ha Low yield 40% area 1300 kg/ha Bare ground 10% area 0 kg/ha Weighted avg. yield (3200 x 0.15 etc) 1700 kg/ha Without weighting (3200 + 2000 + 1300 + 0) / 4 1625 kg/ha Not including bare (3200 + 2000 + 1300) / 3 2167 kg/ha

slide-28
SLIDE 28

28

How much will an animal eat?

Effected By:

  • Quality of the feed
  • Weight and class of animal
  • Intake - 1.5% to 2.5% of body

weight (average range) BUT good estimates require some nutritional knowledge

slide-29
SLIDE 29

29

Feed eaten as % of palatable pasture

  • Eating more than 30% of

palatable pasture reduces diet selection

  • Important from an animal

performance point of view

Carrying capacity (long-term)

How many animals a paddock can carry over a planning horizon (>10 years) without impacting on land condition. It is used for strategic planning.

slide-36
SLIDE 36

What is considered when working out long-term carrying capacity…

  • Land type
  • Average climatic conditions
  • Land condition
  • Tree density

Assessing land condition Two components:

  • Soil condition
  • Pasture condition

That affect your ability to grow grass

slide-43
SLIDE 43

Assessing TBA

  • Tree basal area (TBA)

43

The number of trees impacts the amount of pasture that can be grown and if there is woodland thickening this can be an indication of declining land condition

Practical Application

What do we record in the paddock?

  • Pasture condition

(scale of 1 – 4) +

  • Soil condition

(scale of 1 – 5 ) +

  • Ground cover %
  • Tree basal area
slide-71
SLIDE 71

101

Pasture condition

Healthy pasture:

  • Dominated by 3P Grasses
  • Good density
  • Plants healthy
  • Growing points preserved
  • Few weeds and undesirable species

Soil Condition

Healthy soil surface:

  • No visual evidence of soil

movement (eg. scalding, erosion, pedestalling)

  • No compaction or crusting

Organic ground cover

  • Protects the soil from extremes
  • f temperature and erosion
  • Minimises evaporation
  • Minimises runoff
slide-76

Assessing organic ground cover

Organic ground cover includes;

  • Pasture plants
  • Tree leaf litter
  • Twigs
  • Woody debris
  • Organic crusts
slide-77
SLIDE 77

107

Woody vegetation

Generally, trees compete with pastures for water, nutrients and light. Tree basal area (TBA) is a convenient measure of tree density.
