The Macadamia Farming Program

Macadamia farming
Tree crops like macadamias benefit greatly from the inclusion of Petrik Soil Technology high-grade biological farming inputs in the nutrition program. Our macadamia agronomists consistently find that pest and disease pressure, nutrient demand and water stress can be managed far easier in a system functioning to its biological potential.

Soil Inoculants for Macadamias

The soil inoculants Digestor, and activator Green Manure Plus, have a dramatic impact on root health, root volume and root depth in tree crops generally and specifically with crops like Macadamia that have soil health and compaction limitations.

Improving Soil Health

Digestor transforms the soil health and whole structure, bringing back vital humus into the soil system and utilising the organic matter that is there through a process called in-ground composting.

Most growers do everything to keep a flat surface under the trees. This creates ease in picking, but long term is detrimental to soil health.

Our soil inoculants play such a major role in these systems:

  • improving soil health
  • increasing nutrient unavailability
  • breaking down compaction through humus creation
  • improving water infiltration and rooting depth and quality

Reducing Soil Compaction

Soil compaction is a significant limitation in plant performance in Macadamia farming. Digestor addresses the compaction problems. It works to convert organic matter through to humus and rebuild the soil profile.

Biological Support at Flowering

At the flowering stage, biological support with Setbest provides powerful stimulus, helping the plant through this important stress and growth period.. In Macadamia trees this flowering support is particularly important to increase fruit yield.

It is a common problem to have lots of flowers and only keep a small percent of the fruit. Supporting the plant through these phases makes a major difference.

Integrated Solutions

Soil inoculants support the work of IPM. When the macadamia plant gets its nutrition from its own plant driven fertile system, less nitrogen and other inputs that attract pests are in the system.

Through the use of biology we can maintain peak productivity with lower nitrogen inputs that are known to light up pest activity.

Phosphorus availability is highly linked to proliferation of specific phosphorous solubilising biology. When phosphorous is supplied to the plant via this mechanism the supply of phosphorus becomes plant driven, meaning nutrient supply increases at the stages the plant demands it.

Digestor
Digestor

A microbial soil inoculant
Digestor is a live biological soil inoculant. Its unique combination of multi-strained microbes, fungi and beneficial bacteria build humus, improve soil structure and boost crop performance. It contains species of biology that work in conjunction with both monocot and dicot plants. Digestor is formulated for Horticulture, Orchards and Broadleaf.

Green Manure Plus
Green Manure Plus

The microbial activator
Green Manure Plus is a vital activating blend of kelps and core biological essentials that is applied together with our soil inoculants Digestor or Evergreen. It contains essential “growth food” for microbial proliferation providing vital support during the initial establishment.

Setbest
Setbest

A powerful quality and health stimulant
Setbest improves flowering, aids fruit setting and boosts the overall health and sizing. It optimises nutrient availability at critical stages of plant growth and supports root system mycorrhizal colonies. Setbest builds plant resilience, helps plants recover from damage and is highly effective in all crop types.

Impulse Foliars
Impulse mineral foliars

Rapid uptake of nutrients
Impulse Mineral Foliars supply plants with a highly available form of minerals to increase crop performance or enable rapid recovery from mineral deficiency. Contain biologically complexed minerals combined with microbially digested plant material. This combination provides maxiumum mineral uptake and unsurpassed bio-availability for the plant, meaning smaller amounts of the total mineral content have a greater effect.
