Biological Field

The possibilities for retrofitting the Biological Field are many and varied. Every residential block has soil with a history of use and/or abuse, established plantings, some of which may produce food, and a wider ecological context of sunshine, water, wind, vegetation and wildlife that influence the site.

Part C introduces recurring patterns and proven design solutions for abundant garden farming in suburbia. It doesn’t tell you how to raise seedlings or graft a tree but it will help you select and design the best growing systems for vegetables and fruit trees, along with guidelines on what to grow to make best use of what space you have without moving to a rural property.

Like the first chapter in the Built Field, the Biological Field starts with a series of questions that should enable you to assess the potential for growing and utilising living things on your site: How to assess a garden.

Garden farming explores the different methods that are used to grow food in garden spaces, how you might optimise the available space and the amount of food that might be produced.

The basis of plant, animal and human health is good, well-mineralised soil; Building and maintaining soil fertility covers practical strategies for improving soil at a suburban scale. Managing soil contamination discusses a common issue – that of unwanted chemicals in the soil and some strategies for dealing with them.

Some suggestions on what plants to prioritise in garden farming systems are given in What to grow where and Food growing systems looks in more detail at tried and tested systems for growing vegetables and fruit in small spaces. How these plants might be propagated and distributed is discussed in Seed saving and backyard nursery.

Animals and plants have synergistic relationships in functioning ecosystems, including backyard ones. In Domestic animals in suburbia I discuss domesticated animals that are useful at a suburban scale and in Wildlife in the garden; by and beyond design I extend this discussion out to cover non-domesticated animals, including pest species that may be problematic.

Finally, in Beyond the boundaries we move out from the household garden into larger public and private spaces where different techniques are more suitable.

Biological Field Introduction
The possibilities for retrofitting the Biological Field are many and varied. Every residential block has soil with a history of use and/or abuse, established plantings, some of which may produce food, and a wider ecological context of sunshine, water, wind, vegetation and wildlife that influence the site.

Retrofitting what exists in the Biological Field may involve:

· conserving the rich organic soil created by decades of gardening

· salvaging the wood and mulch from a mature tree that needs to go

· top-working a huge old cherry plum tree back to a modest multigraft plum that will produce a bumper crop long before any new planted tree

· converting part of a garage space into a chook deep litter house

· ripping up paving or even taking down buildings to increase the space for growing.

Permablitzes, which began in Melbourne as permaculture-designed garden makeovers, are classic examples of drawing on community capacity and knowledge to accelerate the retrofitting process.

Applying the retrofitting paradigm to the Biological Field draws strongly on the lineage of permaculture in redesigning agriculture. This redesign is a long-term cultural project that has three primary expressions in suburbia:

· the use of ecological principles and natural patterns in horticulture and animal husbandry at garden farming and urban agriculture scales

· experimentation with a greater range of useful plant species, especially trees and other perennials

· reclaiming the production and processing of perishable foods back to household and community non-monetary economies.

A critical mass of suburban food producing and processing households will enable local monetary economies to develop in at least two ways:

· As households become more self-reliant in food, this will stimulate demand for property design, courses and workshops, nursery production and local seeds, and tools and equipment. Many of these services and products will be bioregionally specific, benefiting local business providers.

· Lots of people are likely to try garden farming, but not everyone will succeed (due to unsuitable site or soil, technical complexity or just plain physical effort in the sun, rain and dirt). However, those who have tried it will appreciate the work and skills required for garden farming and thus will become the logical customers of competent local garden farmers.

14. How to assess a garden

 

This chapter provides an overview of the patterns of sunshine, soil, water and vegetation that make a good foundation for a productive and resilient household economy before discussing the production systems and species that might be most useful in suburban-scale garden farming.

The value of any pattern is relative to its bioregional and market context. These patterns are most appropriate in southern Australia and more specifically southern and upland Victoria (eg Melbourne, Geelong, Ballarat, Bendigo and smaller towns). Outside of this bioregion other patterns may make more sense. These biological patterns should be cross-referenced to those in the How to assess a property chapter that frames the Built Field and the Ownership and living arrangements chapter that frames the Behavioural Field.

In this chapter

  • Balance of sunshine, soil and water
  • How deep is the soil?
  • How big is the fertility bank?
  • Is soil contamination a problem?
  • How much water can I access?
  • How sheltered is the garden?
  • What’s already growing?
  • Vision

15. Garden Farming (Permaculture Zones 1 & 2)

 

Agriculture is the basis of culture and what we call civilisation. It is the dominant activity by humans, covering far more of the planet than human settlements and other land uses. Permaculture is a sustainability and resilience design system that can be applied at any scale and beyond agriculture. However, the most common scale for the application of permaculture strategies and techniques is in garden agriculture, which I defined in 1991 as:

‘… small scale intensive production systems associated with homes and primarily providing for household needs, although tradable surpluses may be produced. Human labour rather than machines provide the major power input. In permaculture site design language we are talking about Zones 1&2 which rarely involve more than 1/2 acre.’

American permaculture teacher and author Peter Bane uses the term ‘garden farming’ in a similar way. I prefer his term and have adopted it: farming implies a way of living without the connotations of industry that has replaced culture in the common understanding of ‘agriculture’.

The desire to produce some, if not all, a household’s fresh food has been common motivation for downshifters and retrofitters. Many people start on this journey with a veggie patch and some chooks as iconic elements of household self-reliance.

16. Building and maintaining soil fertility

 

In Chapter 14, How to assess a garden, I discussed the more permanent soil characteristics that provide the foundation for productive garden farming: large rooting volume, high mineral fertility and Cation Exchange Capacity (CEC), and avoiding soil contamination. This chapter focuses on building and maintaining soil fertility. At the garden scale, this is possible even when the starting point is low in minerals, compacted, sandy or not very encouraging in other ways.

A fertile soil can be hard to define. I think of it as earth that has a crumbly open texture, storing and slowly releasing nutrients and water, hosting a teeming diversity of microbial life and with a balance and abundance of nutrients.

Fertile soil supports healthy growth of plants that need less irrigation, better cope with weather extremes and resist disease and pests. The food from such plants is minerally balanced and dense, has more complex and subtle flavours, generally sweeter tasting with higher levels of vitamins and resists decay for longer. Such food is the key to good health more than any other factor that we have control over.

  • Balance and abundance
  • Strategies to improve soil

Soil and Health Library provides free downloadable e-books, mostly out of print works, about radical agriculture, health and self-sufficient homestead living. The library’s topic areas connect agricultural methods to the health and lifespan of animals and humans – studying these materials outlines how to prevent and heal disease, suggests how to live a more fulfilling life and reveals social forces working against that possibility.

See DIY soil testing links listed under Chapter 14. Some soil testing laboratories that use an Albrecht understanding of soils include:

Pat Colby’s Natural Farming: A practical guide (2004) is a guide to balancing soil minerals in Australian conditions for livestock and human health, albeit more focused on farms than home food growing.

17. Managing soil contamination

Is soil contamination a problem? in Chapter 14 focused on selecting sites with low risk of contamination and on the potential for testing soils for contaminants.

This chapter focuses on strategies to manage known contamination identified through testing or from past history, and possible precautions against the unknown. For those prone to worry about the safety of homegrown food, it also includes general confidence-building measures. It provides some background to better understand this complex issue without becoming unnecessarily stressed about chemical hazards (see also Wood ash, charcoal and creosote in Chapter 6 for preventing contamination from wood ash).

Resources

The VegeSafe program provides a ‘by donation’ testing program for common urban soil contaminants, as well as some great advice for gardeners. Mark Taylor from Macquarie University has been a vocal advocate of lead-safe backyard food production in recent years.

VegeSafe compares soil samples to a range of Australian and international guidelines on soil contamination limits – it is interesting to note that many other countries have lower limits than Australia. Also note that our NEPM guidelines recommending soil <300ppm are based on home grown produce at <10% fruit and vegetable intake (with no poultry). Obviously many resilient households are well above this level!

Soil contamination tests including both heavy metals and pesticides are available from Southern Cross University ‘Environmental analysis laboratory’. 

ABC Catalyst’s Lead Astray episode (watch or text) has some pretty frightening research linking lead exposure in kids to violent behaviour in later life. Also features Mark Taylor discussing gardening in lead soils.

The LEAD Group raise awareness about lead risks and safety. Good general research on lead but not very detailed guidance for gardeners.

DIY lead paint testing kits are discussed in this blog.

Paul Stamets’s Mycelium Running: How mushroom can help save the world (2005) contains an authoritative overview of the principles and practices of bioremediation using fungi.

18. What to grow where

 

Priorities in what to grow are strongly influenced by the climate and soil, available space, water and sun, dietary preferences, and security of tenure. By focusing on Melbourne and central Victoria and, more generally, southeastern Australian growing conditions, we can be reasonably specific about priorities for garden farming by households committed to pragmatic self-reliance.

Although I have only given a few examples of potentially useful species for different situations, these should give a sense of the diverse factors to be considered when choosing plants. The main focus should be but on growing household food but species can also be chosen for their secondary benefits and their ability to perform well in your particular environment.

  • Priorities for suburban food sufficiency
  • Appropriate street trees
  • Multi-purpose shelter and screening
  • Summary

Suzanna Lyle has written two very comprehensive reference books on a wide range of food plants for garden farming: Discovering Fruit and Nuts: a comprehensive guide to the cultivation, uses and health benefits of over 300 food-producing plants (2006) and Discovering Vegetables, Herbs and Spices: a comprehensive guide to the cultivation, uses and health benefits of over 200 food-producing plants (2009). These are an excellent investment for anyone interested in growing food.

Louis Glowinski’s The Complete Book of Fruit Growing in Australia (1991) explores the range of trees crops for the home food producer, especially in Melbourne and similar climates, although we disagree with Louis about the need for chemical fertilisers and pesticides.

19. Food growing systems

 

We can learn the diverse and detailed horticultural skills, and gain the knowledge, to be a successful garden farmer in many ways: growing up with gardeners, volunteering, and from courses, tours and a wide range of books. A Permaculture Design Course provides the overview that you may find helpful in making sense of the voluminous information and often conflicting advice on how to grow food at the household scale. Experienced local gardeners provide both valuable information and plant stock that suits the locality and soil. However, it can still be difficult for prospective garden farmers to decide what will work best for them, not just this season but over the longer term. Soil and microclimate can vary along a suburban street, while every household is a unique context shaping what will work well and be appreciated. The permaculture principle Design from patterns to details suggests that a systems overview can help make sense of the jungle of information and examples around us.

20. Seed saving and backyard nursery

 

Selecting and saving seed is one of the hallmarks of the self-reliant gardener. When we save seed we are:

· planning for the future production of highly productive or preferred species and varieties

· reducing dependence on purchased expensive retail packets of seed or more expensive seedlings

· creating a surplus that can be gifted to other gardeners and/or contributed to more organised seed saving groups and networks.

Although maintaining seed stock of perennials and trees is worthwhile, it is the constant growing, selection and saving of seed of productive annual vegetables which is the heart of seed saving for garden farming. Saving seed is an empowering act for at least three reasons:

· Keeping the best of your own success for planting in future years gives a much greater sense of knowledge and control than selecting a seed packet based on the promotional blurb.

· The quantity of seed harvested from a few fruit or plants gives a great sense of abundance compared with the few inside a commercial packet encouraging a sense of generosity in their distribution.

· Seed saving progressively selects for plants adapted to the local growing conditions and garden farming system. In this way it naturally blends in to the breeding of new, locally adapted varieties.

21. Domestic animals in suburbia

 

In industrial agriculture, animals and crops are generally segregated, often on separate farms. This is a relatively recent development however, and most rural Australians understand that domestic animals and crops can be complimentary in agriculture.

At the suburban scale there are also lots of reasons to integrate plant and animals systems in garden farming. These include:

· the relative ease of producing animal products at the suburban scale

· the high cost of eggs, meat, dairy and fish, the and associated animal welfare issues

· the relatively low cost of bulk grains as source of concentrated feed

· the wide availability of surplus food and green waste from both the household and the neighbourhood

· control of weeds and pests by animals in the system

· yields of manures to maintain fertility

· the value of animals as pets (interest, companionship, children’s learning etc).

22. Wildlife in the Garden; by and beyond design

 

No animal ecosystems are separate from plant ecosystems. This should remind us that nature abhors a vacuum; wildlife moves into any plant system as soon as possible, whether we like it or not. Our responses to wild animals range from synergistic enhancement and aesthetic delight to teeth-grinding frustration and complicated defensive infrastructure – or respectful harvesting of nature’s abundance.

You can find a huge range of information about how gardeners can encourage wildlife into gardens, but not so much of this is relevant if you’re engaged in serious garden farming. Jackie French’s Wilderness Garden (2007) distils her decades of experience growing food in a bush landscape where the benefits and the problems of wildlife are constant factors shaping her philosophy and practice of gardening.

23. Beyond the boundaries (Permaculture Zones 3 & 4)

 

The suburban retrofitting strategies discussed in this chapter are applicable to larger areas of public and private land beyond the boundaries of individual residential lots. Consequently, their implementation may depend on community-level organisation and support of local government and/or large property owners. City farms and community gardens may be the starting point for projects that could become the models for a comprehensive re-ruralisation of our low-density cities.

Some of my proposals are still too radical to be taken seriously in the current public discussions about redeveloping urban space; these ideas will have to wait until energy descent symptoms compel society to grasp opportunities to re-ruralise the management of urban landscapes.

You may be able to apply some of these strategies and proposals informally if you are able to make opportunistic use of vacant and unused land when the notional owners and/or managers are unable to do so. Everything from urban foraging and skipping (‘dumpster diving’) to grazing, beekeeping and even forest harvesting will expand in energy descent futures. Although these activities can be seen as representing the breakdown of orderly land use planning and markets, if not law and order, they also have the potential to create new ‘commons’ that in the future will be managed by local communities using protocols and sanctions that evolve over time.
