Deep Ripping Not Appropriate for all Soil Types

A comprehensive understanding of the cause and location of high soil strength is required before undertaking deep ripping as research has shown it is does not provide an economic solution in some soil types.

KEY POINTS

  • Deep ripping of compacted soils is most likely to improve grain yields on sandy soils and where compaction has occurred on upper parts of the soil profile through machinery traffic or livestock trampling.
  • Deep ripping is less effective on heavy clay soils unless combined with gypsum on sodic soils prone to waterlogging.
  • Deep ripping will provide little benefit if other subsoil constraints such as salinity, sodicity or acidity are also present.
  • Recent advances in machinery, such as ‘slotting’ and deep placement equipment to simultaneously introduce ameliorants at depth with ripping, could increase the financial and agronomic effectiveness of this approach to managing subsoil constraints.

Tri-Cone Tree Guards

tree guards by BDPAUSTRALIAN MADE TRI-CONE TREE GUARDS

DESIGNED FOR THE WAY TREES WANT TO GROW

These distinctive, highly visible pink tree guards are made of UV stabilised fluted plastic and are designed to protect seedlings from:

  • Herbicide drift
  • Wind
  • Sun
  • Dehydration
  • Predators
  • Adverse conditions

KEY BENEFITS

  • Can be re-used up to 3 times
  • Strong and durable for Australian conditions
  • Fully recyclable
  • Easy to install with a single stake
  • Easy to remove
  • Promotes improved growth rates
  • Packs flat for easy storage and transport

The tree guards have been used at the National Arboretum Canberra to decrease wind, rabbit and kangaroo damage to saplings:

SIZES & PRICING

  • Pioneer Guard: 250 x 130 x 95 mm high. For fast-growing young upright trees (e.g. eucalyptus, casurinas, acacias).
  • Shrub Guard: 500 x 280 x 380 mm high. Suitable for wide spreading low-growing shrubs
  • All-Rounder Guard: 380 x 250 x 600 mm high. Gives greater protection for slower growing trees which need long-term protection
  • Jumbo Guard: 600 x 300 x 755 mm high, requires 2–3 stakes. Ideal for advanced trees and fruit trees which need ultimate predator protection. Will protect from animals up to the size of a sheep

Traditional sizes:

  • 550 mm x 550 mm x 900 mm (stakes/mat not included – need three 22 mm x 22 mm x 1500 mm stakes stakes and a 650 mm x 650 mm weed mat) – Suitable for orchard trees and advanced trees. This guard provides the ultimate protection against predation
  • 550 mm x 550 mm x 1350 mm which is created from one and a half 550 mm x 550 mm x 900 mm guards (stakes/mat not included – need three 22 mm x 22 mm x 1800 mm stakes stakes and a 650 mm x 650 mm weed mat) – Suitable for orchard trees and advanced trees. This guard provides the ultimate protection against predation

We can also design and construct tree guards to suit any specific purpose.

why pink tree guardsWHY PINK?

Visible light can be split into a spectrum of colours. Green leaves absorb light from the red fraction to drive photosynthesis. Research has demonstrated that the colour pink reflects and focuses the red fraction, concentrating this photosynthetic energy to enhance plant growth. (Other colours are available on request)

As you can see in the comparison here, the pink colour of the guards accelerates growth due to stimulation of photosynthesis.

ADDITIONAL INFORMATION

  • Store in a cool, dry environment out of direct sunlight
  • All guards require stakes
  • Tree Guards include a hillside fold for sloping sites, and an optional anchor pin for high wind zones is available
