Workshops and Courses

Small Microscope


This is a practical workshop to supply the participants with the skills to conduct qualitative assessments on their compost teas or compost inoculum. It includes training on how to use your small microscope and recognition of the following groups of organisms: bacteria, fungi, protozoa and nematodes. Attendees are supplied with a manual describing in detail the workings of their microscope, colour prints of microbes and qualitative assessment template/sheets.

The day –long course is primarily aimed at first time users; farmers making their own compost inoculums or teas, and input suppliers producing inoculum on a commercial scale. The cost is $150.00 plus GST per person.

As the training is quite intensive and hands on, each student must supply their own microscope with the following specifications:

  • 3 objectives (4x, 10x, 40x) many microscopes also have 100x objectives).
  • Binocular is recommended. (2 10x eyepieces).
  • Its own light source and adjustable light condenser.
  • Fine and course focus ability. • Fully adjustable stage and slide holders.
  • They may interface with computers and have built-in cameras.
  • Slides and coverslips may be purchased from the Soil Foodweb Lab.

These microscopes are easily obtainable in NZ and range in cost from $750.00 to $1400.00.

Workshops and Presentations to

Farmer and Industry Groups

Here at the lab we have created a specific series of workshops that are delivered in layman’s terms to enable attendees to easily grasp the concepts and readily put them into practice in their production systems.

Our tutor, Cherryle Prew has had 25 years experience in the biological production methods and has practical ‘hands-on’ experience for most agriculture and horticulture systems in New Zealand. Her teaching method is informal and  interactive, with a strong focus on encouraging a sustainable conversion to biological practices. Her mission is that the farmer-grower moves into the new biological regime allowing their soil and systems to progress at the same rate as their mind set and confidence levels.
