Making a wetland in a stony hole

Making a wetland in a stony hole

Details   Attempting to modify water holding capabilities of this stony soil by introducing water loving, wetland plants while actively removing the rocks and gravel. Pulsing diverted run off water and pigs through this muddy hole is slowly shifting the conditions and creating a new assortment of niches. Amplify the diversity!

Energy efficiency with hot water

Currently most of out hot water heating is done by electricity although we are are working on a number of strategies to reduce this component. One part of the approach is to keep the thermostat set so that the water is just hot enough.

I was having a conversation with someone about energy efficiency and hot water heating and what was the best temperature setting for the hot water cylinder.

The friend was operating under the incorrect assumption that it was better to have the cylinder as hot as possible so that when water was taken out, for a shower say, there was less cold water entering that required heating. There is a certain surface logic to this but it seemed to me that it doesn't matter what temperature the water is, when you have a shower or do the dishes you are extracting the same amount of energy (in the form of hot water) from the tank and so the energy needing to be replaced is the same.

The issue with keeping water extra hot then, is more to do with the extra energy that is required to maintain a greater temperature  differential between the temperature inside and outside the hot water tank.

According to one website:
"The ideal setting is 60°C. It is important that the water in the cylinder is this hot to kill bacteria such as legionella but higher temperature settings only increase your power bill."

Restoring China's Loess Plateau

Restoring China's Loess Plateau

Home to more than 50 million people, the Loess Plateau in China’s Northwest takes its name from the dry powdery wind-blown soil. Centuries of overuse and overgrazing led to one of the highest erosion rates in the world and widespread poverty.

Two projects set out to restore China’s heavily degraded Loess Plateau through one of the world’s largest erosion control programs with the goal of returning this poor part of China to an area of sustainable agricultural production.

Harvesting rain

Harvesting rain

It's raining today (as they said it would) and it's bloody marvellous. As a free resource, rain should be collected or focussed for use in the right spots at the right time.
One of my processes includes home made guttering, a bath, and an overflow pipe

Raised woody swale / hugelkultur construction

Raised woody swale / hugelkultur construction

Details   We used the opportunity of having a small excavator on site recently to construct 5 wood filed raised growing mounds on contour.
This technique is often called hugelkultur and exploits the ability of rotten wood to absorb and hold amazing quantities of water which is later made available to plants growing nearby.
The end result was 5 mounds about 7 meters long and half a meter high, each packed with a full trailer load of rotten willow logs and a wheel barrow of pig manure.
An assortment of fruit trees and berry shrubs has been planted along side in various locations to capitalise on the moisture, slow release of minerals and micro-climate effects of wind, shelter, sun and shade.

Fertigate with ducks

Fertigate with ducks

A simple and effective way to fertigate (fertilise while irrigating) fruit trees or other productive plantings using an old bath tub. Like all good permaculture solutions, this stacks functions by providing the ducks with a source of water to enjoy while collecting their nutrient, discharging it via gravity. It could also provide some thermal mass to help nearby plants during cold times...

Water smart design and land use

Water smart design and land use

Plan for dry and survive drought with carefully designed and implemented rainwater catchment systems built directly into the landscape. Three core elements to mitigating the effects and impact of drought:
  1. Identify and intercept water flows to keep moisture on the landscape
  2. Improve soils ability to absorb and retain water
  3. Reduce the impact of hot, dry winds
Find out how simple land use patterns and strategic planting can achieve all these benefits and more.

Living on contour - working with water flow

Living on contour - working with water flow

Water is the essence of life and as such we need to be thinking about how to make best use of what we have. The most important work we do is to implement solutions for capturing, storing, diverting and infiltrating rainwater and runoff. This helps build soil, nourish crops, prevent erosion, minimise drought and reduce or eliminate irrigation needs.
Learn about the art of land shaping for natural rainfall catchment, a practical guide to water harvesting and management.
Make the most of the water available, direct surplus water away from wet areas towards dry areas.
Use swales and terraces to halt the flow of water and nutrient off the land and allow it infiltrate and hydrate the soil.

Solar - third time lucky

Solar - third time lucky

After several failed attempts to create a low cost, low tech solar water heater I gave in and purchased a complete kit off the shelf. It's only August but we've been having some nice fine days and the temperature has been getting up to high 50's. This unit has 20 evacuated glass tubes with some kind of antifreeze that exchanges heat with water that is pumped through the header. While I would have preferred a passive system I do like the modular nature and programmable smarts of the control centre.

Sprinkling (at high pressure)

Sprinkling (at high pressure)

Details   It has been really drying out and we have been busy moving hoses to  water as many trees and veges as possible.
We have a well with a pump that delivers 25mm of water at high pressure. While I was trying to come up with a way to apply this water gently to the garden I came up with this simple circular terminus mister (click for photo).
It effectively produces a 4 meter high column of mist. Wonderful on a scorching afternoon.

Freshly created swale

Freshly created swale

Details   It's never too late to add another swale, it's just a matter of squeezing it in amongst the existing plantings, fences and other obstacles.
The swales not only do a fantastic job of capturing and infiltrating surface runoff during rainy times but also break up the land in interesting and attractive ways.

Creating a pond

Creating a pond

Having recently purchased Gaias Garden, a book on back yard permaculture, I was inspired to create a water 'feature' to extend the diversity of the local biological system.
This is an unlined pond dug by hand down into the clay and has a water depth of no more than about 40 centimetres when full.
