The Probitas System mission statement
Deliver the knowledge, support and products needed to progress a biological farming system to natural self-sufficiency.
Reinstate a farming system’s natural soil, soil biology, plant and animal energy cycle.
Key tasks
  1. Facilitate the implementation of a pasture / animal management system that reinstates the natural soil, soil biology, plant and animal energy cycle.
  2. Facilitate the identification and removal of factors that impede the reinstatement of the natural soil, soil biology, plant and animal energy cycle.
  1. Facilitate the measurement and analysis of the natural resources and recommend the most cost effective and practical processes and products required to achieve natural self-sufficiency.
Expected outcomes
  1. Optimum forage diversity and rest / recovery time for pasture plants is created so that soil / soil biology, plant and animal energy is accumulated and not borrowed forward.
  2. The dependence on buying energy (fertiliser) to address the soil / soil biology, plant and animal energy deficiency is removed.
  3. Animal health issues that are created by exposing animals to overgrazed pasture with low true protein levels and high parasite larvae contamination are removed. 
  4. The loss of soil carbon through oxidation and the ingress of moss and weeds as a consequence of over grazing that exposes soil is prevented.
  5. The requirement for hay and silage supplements and the capital equipment or contractors and the need to fund maintenance, labour and running costs is removed.
  6. The genetic potential of the soil biology, the plants and the animals and weaning weight and growth rate opportunities are optimised and genetically superior animals are promoted.
Delivery of knowledge
The Probitas System includes a strategy of placing an economic value on knowledge, client support and technology.  This has enabled us to remove our financial dependency on product sales and thus avoid situations where a product could be promoted, to a client only to create a sale for cash flow purposes when that product would offer no benefit.   Also avoided is the situation where a decision has to be made on whether to continue to service a client for no financial reward because no products are required or being forced to end the relationship with that client for economic reasons.
Probitas System clients are offered the choice of either becoming a Probitas System member or a Probitas System non-member.   The member pays a subscription that buys at least four visits per year plus product discounts and access to the web site member’s area.  This subscription covers the cost the Agent incurs in servicing the client.  The non-member pays the Agent for time and travel but gets no other benefits.  In both cases the Probitas System Agent is not financially dependent on product sales to cover their expenses.

The Probitas Systems Five Steps Programme
The following five steps are required to create the environment that is needed to produce food that is fit for purpose.
Step 1
Create a soil environment that facilitates optimum soil biological function and plant nutrient availability.  Use the Brookside Laboratories suite of soil tests to measure if mineral amendments are required to repair the soil environment. 
Step 2
Address the soil's natural electromagnetic energy to optimise the solar energy pathway and facilitate soil, plant and animal detoxification.
Step 3
Identify and deactivate toxic and unnatural frequencies, including electromagnetic radiation from cellular networks, contaminants in electricity and radioactive and Ag chemical toxins, that are held in the soil silica that disrupt the natural energy flow and impede plant, animal and human health.
Step 4
Introduce nature's 90 elements from the sea to ensure that complete genetic sequences are passed on.  Introduce fungal mycelium species that are required to allow unimpeded nutrient cycling. 
Step 5
Introduce complimentary forage plant species that allow plant energy availability throughout all four seasons.
Adopt grazing management systems that facilitate optimum plant energy availability, optimum plant nutrient recycling, the maintenance of forage species diversity and efficient, natural buffering against climate extremes.

The Probitas System was developed by farmers for farmers



Ewan Campbell is a typical ‘kiwi bloke' who grew up on his father's dairy farm near Te Aroha and became thoroughly familiar with what constitutes poor and deficient land. He bought a property near Waihi and began farming on what was initially very depleted soils holding some of the highest aluminium levels of any soils in the world according to Brookside Laboratory. During sixteen years of observations and trials Ewan developed an eco-safe and sustainable system of farming based on complete mineral and biological balance. He also undertook a period of study of soil testing methodology with Brookside Laboratory from the United States.

Fonterra has detected traces of the nitrification inhibitor dicyandiomide (DCD) in cows milk. The following is pertinent:

Two extracts below from the "facts box" in Alan William's article in the latest NZ Farmers Weekly:


DCD was developed about 30 years ago and is a non-toxic, water-soluble compound that breaks down rapidly in the soil and leaves no lingering residue.  What research did Alan refer to when verifying this statement?  If this statement is true then are the DCD residues that have been detected in milk a consequence of:

  1. The product not being used according to the product label directions for use?
  2. The fact that the product label information does not warn the user that inproper use may lead to product residues contaminating milk (and meat)?
  3. "Treated" pastures being grazed too soon after product application?
  4. The fact that the product label information does not include a pasture withholding period to allow DCD pasture residue to be washed off the plant and absorbed into the environment?

New Zealand is the only country spraying DCD on to pastures though it has a range of uses in other countries.  If this is true then there will be no overseas research on the behaviour of DCD sprayed directly onto pasture in terms of:

  1.  its residual capability on the pasture. 
  2.  Whether it is uptaken by plants through plant roots into the leaves
  3. Its accumulation in the pasture consumers blood or milk.
What research into the above was required of Ballance Agri-Nutrients and Ravensdown by the regulatory authorities before they were given approval to release the product for general use and what research was actually done and published by these two companies?
