Making Regenerative Fertiliser


Building your garden into a regenerative, highly-productive ecosystem is a multiple year-long journey. But you have tools at hand for speeding up this process WITHOUT reaching for industrial fertilisers.

This video series teaches you how to create your own locally-sourced, regenerative fertilisers. These are valuable resource to increase the pace at which your soil:

  • Builds carbon
  • Balances its minerals
  • Fosters its microbial population

All without unlocking the carbon and degenerating the soil!

You’re going to learn the entire set of strategies we use here at Kōanga: biointensive compost, worm farming, ramial wood chip, biofert, different liquid fertilisers including fish hydrolysate, biochar, chicken compost, and bone & shell ash. 

If you’ve watched our workshop, Growing Nutrient-Dense Food, you’ll already understand the principles and laws of nature that underpin these fertilisers.

This workshop builds on these principles and gives you step by step, easy to follow instructions for creating these fertilisers at home.

Also, most fertilsers today, even a lot of organic natural options are unbalanced, they add too much of this and not enough of that.



  • Self-paced online workshops with video lessons and complementary reading
  • Booklets and many other assets, all in digital formats
  • Kōanga Student Facebook page for support and questions
  • Taught by Kay Baxter (Kōanga Founder)

  • Schools and educational projects looking for more resources to support their curriculum


Here’s the lesson plan



  • Learn about the paradigm shift that takes place when we stop buying fertiliser
  • Learn how beneficial it is to pair this course with the Growing Nutrient Dense Food workshop to get the most out of this journey
  • Learn how to support your plants with locally sourced minerals while you’re still working on building your soil
  • Learn that regardless of the strategies we use, the bigger picture is always about following the principles of science and the laws of nature, and reconnecting to the natural world!


Ramial Woodchip

  • Explore what Ramial Woodchip is
  • Learn how RWC feeds the soil and in turn feeds our plants
  • Learn more about how Kōanga has used RWC in both seed gardens and forest gardens and the positive changes it has created
  • Learn how RWC can be a game changing tool for local regenerative food production
  • Understand how RWC can change your soil in many ways including its fertility, aeration, and structure
  • Receive Kay’s advice on how to use RWC when growing specific vegetable crops such as: tomatoes, pumpkins, peppers, beans, garlic, onions and more
  • Explore how much RWC is produced by each square metre of tree
  • Learn that using a diverse and integrated range of strategies to create soil fertility will create the best results
  • See Kay’s garden in mid-summer and hear her final observation about the production and use of RWC


Liquid Fertilisers

  • Receive an introduction and overview of the liquid fertiliser process
  • Learn Kay’s main lessons around the whole liquid fertiliser story
  • Learn how the Biological Agriculture principles changed Kay’s strategies when it comes to making liquid fertilisers
  • Understand the importance of attaching your water soluble nutrients to carbon when making liquid fertiliser 
  • Receive step by step instructions for how to make different liquid fertilisers including Bio-fert, Fish Hydrolysate and more
  • Understand the benefits of each ingredient included in these recipes and the role they play in your garden
  • Learn how you can tailor make your recipes based on what you need in your garden and what you have available locally


Worm Farming

  • Watch Kay demonstrate how our worm farming systems work and how to manage them
  • Learn how to use food scraps to create vermicast, a valuable resource when your goal is growing nutrient-dense food
  • See the design for the wooden boxes we use in our worm farms
  • See the final result of our worm farming system: beautiful and fertile vermicast ready to use in the garden
  • Learn how you can use these same boxes to store your roots crops and save space in the garden


High Carbon Compost

  • Watch the Kōanga Garden Crew make a 60:1 compost heap in the Thorny Croft isolation seed garden, using the principles of the biointensive method
  • See how we build a heap from beginning to end using added minerals to build soil and high BRIX seeds
  • Get a visual reference for the ratios of carbon and nitrogen going into a 60:1 compost heap
  • See that building amazing compost is something anyone can do!


Chicken Compost

  • Learn that while there are other ways of making compost, the ‘laws of nature’ around building humus still hold
  • In this episode you will watch Kay create a system for her chickens to make  compost in the chicken house
  • Learn the key things to keep in mind to ensure this method is capable of being useful in the garden or forest garden



  • Watch Bob describe the pattern language of a steel biochar kiln, noting the angle and shape of it in order to replicate this with a whole in the ground
  • Learn more about the relationship between biochar and humus building process, and different ways to activate your biochar before using it in your garden
  • Get advice on how to choose sources of wood to be used for the biochar burn, RWC or rocket stove fuel


Bone & Shell Ash

  • Learn how to use a bonfire to burn bones and shells and make an excellent source of nutrients for your garden
  • Watch Bob placing the bones in a bed of embers in such a way that all bones get hot enough to be easily crushed in the next day
  • Learn the this bone & shell ash is particularly high in calcium and phosphate which are both essential for plant growth
