Kay’s Garden Blog August 2016

Spring is around the corner and I haven’t written a garden blog for a while, I have a new greenhouse /garden shed about to be ready for use and finally after months of agonising I’ve decided how to cut down the number of hours I require to spend in the garden to keep it looking incredible and producing large amounts of high brix food.


Our garden is 200m2 plus 50m2 of perennial beds. I’m leaving the perennial bed as it is, Purple Asparagus, Purple de Jesi globe artichokes, sea kale, Hong Kong 3 rhubarb, Multiplying spring onions, Welsh Bunching onions and day lilies (edible flowers) All of these crops are highly productive, taste fantastic and are ready to eat just when we need them, Spring.

The rest of my garden feels too big now, we have come a long way in 5 years in terms of building up the soil and I feel as though I can grow just as much food in a smaller area, The biggest challenge of all is to stop bringing in fertiliser to keep the process of regeneration maintained in the soil and the health of the crops. This is a graph showing just how much we have built the soil in our home garden …. .. using the following strategies, over the past 5 years

graphics new

  • Learning to make compost that is actually useful, adding balanced EF fertiliser, plus clay, biochar, seaweed and clay shards
  • Using Environmental Fertilisers based on Reams soil tests

Utilising Biointensive practices whereby we grow 50% of the garden in compost crops each season

  • Growing carbon crops in the garden that unlock needed nutrients eg lupins and oats

I have decided that this year is the year I’m stopping buying fertiliser… and that feels like my biggest challenge ever, I’m also totally committed to growing soil and high brix food and I want to grow as much food on less area to save time.

When we came here the brix of the grass was 2, way too low to maintain our human health or for the soil processes to be regenerative.

This season I’m committing to going the extra mile to close the loops, now that we have got our brix levels up and soil building happening fast (and we’ll keep testing to watch what happens) my strategies are going to change a little… as follows:

  1. Continue to make high quality compost using carbon crops from the garden and compost heaps with a 60:1 carbon ratio and high quality ingredients (as described below)
  2. Begin consciously and carefully using all of our urine and humanure in the vegetable garden. It seems clear from the research (see below) that 1 person’s urine for 1 day is an appropriate amount to return to 1m2 of garden bed or soil twice a year. That means you could feed 175m2 of garden per year using 1 persons urine (balanced with the composted humanure as well) With 2 people in the household that means we can feed an area roughly 350m2 which is exactly what I have worked out that we need to grow all of our vegetables and grains in our soil this year. That means I can take 6 beds out of my rotation, 2 beds out of blocks 2 and 4 and 1 bed each out of blocks 1 and 3 in the rotation. Those beds I’m going to plant in the best perennial crop I know that can be regularly harvested throughout the year to make compost or mulch beds such as the perennials and the tomatoes and peppers and pumpkins
  3. Grow perennial alfalfa in 6 of my previous garden beds. Alfalfa is a serious contender for our most valuable dynamic mineral accumulator especially for unlocking and recycling calcium and phosphate which are the key minerals we need to be bringing into our soils.

A piece of research that has helped me take this step is the paper written about recycling human urine and humanure (READ HERE)

After reading this and having watched the Kotare Village work through designs for recycling human urine and humanure for all toilets in our houses and the village and Koanga I now feel able to use the urine and composted humanure in ways I can talk about publicly and recommend.  Kotare Village is in the process of putting these plans through the Hawkes Bay Regional Council so when we have them approved, I’ll let you know.

In the meantime it goes something like this (it is very simple) collect the urine or most of it separately, in a urine only bucket or have a urine separator on the toilet system. It must not have fallen down through the humanure bucket, (it must be just urine) and then add a carbon source to it such as vermicast, sugar, humates, or biochar.  Adding a carbon source holds the nitrogen and means it stays in the root zone of the plants available as a slow release fertiliser, rather than being water soluble and washing into the water ways with the first rain. I don’t want to have to buy anything to do this and we are making biochar/bonechar on our house site twice a year, 200 litres at a time, so we are collecting the biochar/bonechar, storing it in barrels and then adding urine to charge the biochar/bonechar and lock up the nitrogen.

I’ll use that in place of fish fertiliser or a pick me up for all heavy feeding plants. The humanure we collect in buckets, which contain humanure plus leaves, a little dirt and a little wood ash and some urine so that it is moist. These 20  litre buckets are then tipped into a larger barrel. A house of two people will need 2 of these larger barrels. And after you fill up the first one put a lid on it and keep in a warm place while you fill up the second one. It will take 6 months for the first one to become friable compost ready to go on the garden and then swap over again. I’ll plan this so that the barrels of compost are ready to use either straight onto the garden at planting time or bed preparation time or into my usual compost heaps.

Either way the nutrients will be retained for the garden because we don’t let our compost heaps go over 50°c holding the carbon in the compost to be returned to the soil in the form of humus. (see Koanga Composting Booklet (LINK) for more details here). One of the amazing things about our urine is that it is not only a fertiliser but it is a communicator through the microbes and the soil to our plants showing them what we need, to improve/balance our health. This may sound farfetched but Ayuvedic medicine as practiced in India for thousands of years recognizes the value and healing properties of our own urine. Our own urine on our own garden soil will communicate to our ecology in a way that is a vital part of the process of coevolution (part of the process of creating a regenerative ecology) it’s amazing, it’s free and we all have access to it!

So I’ll continue making compost, I’ll continue adding bone char and biochar to the compost as well as clay and pottery shards, seaweed,  and as many ingredients as I can that contain high levels of phosphate. The calcium will be the burnt crushed egg shells plus the bone char soaked in soldier fly liquid which unlocks the calcium and the phosphate

I’m sure we can do it, grow soil fast, grow high brix food and reclaim our health and that of the ecology around us. I’ll spend the rest of my life fine tuning this process and enjoying the journey…… stay tuned …. It’s exciting stuff!!!

I’ve used the Koanga Garden Planner to redesign my garden this spring to ensure I have the rotation systems in place, enough carbon crops to know I will be able to make enough compost to grow my soil, and the right balance of crops to ensure we have a balanced diet year round!!!

If you find all this stuff interesting then would love to know more please join us for a workshop or two this spring, Some of you might enjoy staying over during the week in between 2 workshops so you can do both workshops and have a good look around while you are here. Talk to Trena if you are interested in this at [email protected].

If this feels like your life journey, something you want to know more about to take back and teach and continue learning then maybe the last spot on our Spring Internship is for you!

Organic vs Nutrient Dense Food

Organic Food

  • Cutting out all the nasty chemicals (not using pesticides, herbicides & fungicides)
  • Only using natural products that come from the environment (not synthesised) on your garden beds and plants
  • If you start with an already degenerated environment (which we mostly are) then you will be recycling the same deficiencies that exist in the natural products your fertilisers and plant applications are sourced from
  • It’s possible to be organic and degenerating the soil (I did it)

Nutrient Dense Food

  • Highest potential of mineral energy available to the plant
  • Use natural products but discover missing gaps in minerals and supplement them, not just focusing on a few, but all 84 minerals
  • Measured by Brix testing which tells us the solids per 100 units of plant sap – this allows us to test and see if our fertiliser program is effective
  • Increasing nutrient density of our plants is inseprable from increasing our soil and sequestering carbon and hummus in the soil
  • Learning to grow nutrient dense food is a journey of regeneration

‘Apple Tasting’ is the new ‘Wine Tasting’

This week Kay held a tasting at afternoon tea for our Koanga Institute Staff. We compared some of the apples in our collection and learnt a bit about their cultural heritage too and how they came into the Koanga Collection. Next year we’ll incorporate it into some an open day so you call can discover your favorite apple variety before planting your fruit trees.
If you would like to know more about our fruit trees we send out full info on cultivars in our July Catalogue each year. To get the catalogue become a member here: http://buff.ly/23w8Jx7
